Grey Screen (NO REACTION) - Please help me out guys - G2 and Desire Z General

Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg

C'mon guys:-(

So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)

Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that

sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance

No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com

you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it

How much would the last option cost?
And how much do you guys think HTC will chare to repair it?

something like that if its the ribbon cable.... but that gives you the whole kit

thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one

Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.

looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey

Done
And thanks again for your help.

alrite glad i could help, if you get stuck or if the warrenty doesnt work come back

hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?

Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Well it's just like it was when I bought it, 2.2.1, only google apps, had to configure sim again no sms, etc.. But my phone is definitely now new because there are my scratches on the back of the phone.

I didn't quite understand your reply, lol sry, but I did see one big clue....2.2.1. Which means you should have no problems rooting again.

I don't have any problems with rooting again, I was just saying that I was confused that I got my device repaired for free, although they unrooted my phone.

Touch screen broke

Hi! I Love ( D ) my TD2... to bad my touch screen broke already (2 months after purchase) without dropping it or whatever.. Screen and phone works normal.
Im just curious if there are other people having this problem jet?
Do you guys think im f*ck'd? or does htc replace touchscreens within warranty?
if not; Does anybody know what the costs may be for replacing a touchscreen? And is it possible to replace only the touchscreen or must the whole screen be replaced?
A lot of questions , i know.. hope someone can give me answers.
Thank you!
new screen
see here, a similar discussion: http://forum.xda-developers.com/showthread.php?t=537654
if the screen broke and it was not your fault, warranty should cover that ... it seems that buying a new screen and putting it is easy ...
thnx for reply georgeono! guess i'll try warranty first.
same here...touch screen cannot sense any form of touch
Hm.. to bad man. when i put my phone under a bright lamp or in the sun i can see some kind of liquid under the screen(so i know its definitely broke..), same at yours? did you contact warranty jet?
i guess the screen is just not that strong, cause i have treated this phone much much better then my old htc touch and that touchscreen is still working..
my batt went flat...
I go home and charge it..
before full charge, I sms and it is not working anymore..
Soft reset or hard reset no use..
Next day, I see the "liquid" screen under sunlight...
I also take care of it well as this is my first pda and most expensive hp i ever bought...
Going to sent in on this coming thursday...
How about ur warranty, void or consider under warranty??
havent found time jet to send it in but i'll send it tomorrow so i'll let you know. .
I have had the same problem. I sent it back last Friday and have had notification on Monday that it arrived at HTC, but the tracking details they gave me don't seem to do anything. They say it'll be 5 to 10 working days before I get it back.
The engineer on the phone pretty much straight away described the problem as 'LCD Leak' and that was also stated on the postage label they sent through to me.
I found a short term fix for the problem before i sent it off: When you see the touch screen has the patch of liquid inside, use a piece of sellotape or other sticky tape and gently pull the touchscreen outwards away from the phone and it becomes usable again as long as no fluid is touching the screen any longer.
Hope this makes sense.
edit: I got my phone back and the same problem was still occurring - it looked like they had simply take taken the screen off and put it back on again. It has gone back again, but hopefully this time they will actually look at it.
hm i tried your fix but it didnt work for me ..thnx for the tip anyway!
Same like here I think:

i had the same problem and i can tell you this is caused by too much pressure on the screen. it seems the screen does fall into the phonecase and therefore free itself from the glass. take care with that phone in the pocket!! also the manual says, take out the phone of the pocket when you sit down!! i was shocked when i read that... i mean.. wtf.. what is the idea of a mobile phone which you cant have in your pocket???
haha , and they used to call it a pocket pc! too bad i havent read the manual BEFORE i bought this fragile peace of sh..

Your just a very unlucky man...
I really love my TD2 and it's working as it should be.
I do not use a case and have it just "naked" in my pocket (without keys and other stuff in my pocket) and its no problem, no scratch...
And i don't call it fragile, ok... it can break easier than a rock in your pockey but still..... I don't know how your TD2 is but mine cant bend a 1/2 mm, it's pretty though.
Phone fixed.... For now
I have received my phone back after a second trip back to HTC and it appears that they have replaced the whole frontage of the phone as a tiny scuff on the metal bit and a miniscule scratch on the screen have gone. The internals of the phone are the same as it has the same serial number and IMEI number.
Its all working so far, I've had no evidence of the fluid in the screen as yet and hope not to again!
Send it back and it will be mended eventually!
Had a similar problem, after 20 days the display broke (not on the surface but under it) because of...who knows, maybe direct sunlight since it was on the seat of my car.
Now, after reading the post, I see it's not a singular problem but also other lucky customers are dealing with it.
The real problem is HTC service. I contacted HTC Italy and they told me to take the PDA to a collection point along with a letter describing what happened since I asked for the warranty cover. After 20 days they told me I have to pay 126€ to repair my D2 because the service decided that it was due to my manomission (aka : you have lied to us). After some enraged mails I sent to them, they replied me I should contact HTC in UK to have the warranty. I decided to pay to have my phone back quickly but until yesterday no answer.
Today I sent another email and HTC replied telling me that the service center is closed for holidays until 24th...
I let you imagine how disappointed I am with HTC and they call it HTC Service Excellence.
Ok, it was my fault...I knew I had to buy the spare part on my own and change the LCD but I trusted the HTC name...big big big mistake!
Just consider those experiences in case you think to send your phone back to HTC service...I will never do this again!
Thank you guys, now I know for sure it was not my fault.
I have my TD2 now 3 month and I recognize the problem others mention. Although this problem is a fault, the system is not broken.
When the phone blocks, look for the "liquid" below the screen. It can be very small to fingertip size. The screen is not broken but the touch screen sticks to the display screen. It occurs by applying some force while using the touch screen. Of course this should not happen but it locks the phone or results in unpredictable touch inputs. IT IS NOT BROKEN.
It can be easily solved. Just wipe, with some pressure, with your thumb over the touch screen starting from well below till above the affected area. The touch screen detaches from the display screen and everything works again.
The solution would be a mod by HTC to prevent the two screen from sticking together.
I hope this helps by preventing people to send their phone back and foreward unnescessary.
Just send in my TD2 today for the same reason. Hope they wont simply "lift the surface up" and send it back to me.
repaired!
i had to wait a long time, but i got a message today that the phone is repaired within the warranty by an external repair service. Hopefully the problem is solved now, but im very glad to hear its not gonna cost me 200 euro's or so!
for the dutch : ondanks alle slechte verhalen over dynafix (volgens mij de gebruikelijke repair service voor een htc telefoon in nederland) is het toestel gewoon gerepareerd zonder onzin over drukschade etc. !
update
got my phone back yesterday , in fact they replaced my old phone with a brand new one! Totally free of costs. So i'm a total htc fan again!

Are you sure it's new? I thought they replaced mine as well (after a LOT of phone calls and hassle), but the serial number is still the same.
The counters had been reset, so at first I thought it was a brand new one...

I think my screen is dieing

When I try to wake my phone from standby the screen lights up half way then becomes interlaced and sometimes gets filled with bars of color. If I keep pressing the power power essentially taking the phone out of standby and putting it back into standby the phone will eventually wake up from it's slumber and everything will be just fine until it goes back into standby again.
SO, before I scrap the phone I was hoping the wonderful people on this forum would have a magical solution. I'll post a vid of what's happening tonight when I get home if needed.
BTW
my phone is running
cyan 4.04
Danger SPL (I think that's what we're still calling it)

Well it's similar but not the same. Mine does sometimes go completely white but not often it usually displays half the screen for a second and then goes completely black with the backlight still on. Mine happens whether I press any buttons, slide it open, or any other way to take the phone out of standby. My phone has been doing this for awhile now, how long I'm not entirely sure it's just recently become an annoyance that I will no longer put up with.
I've tried using a new battery and a new sd card neither seemed to have helped. Now my only ideas are [A] the phone is just f'ed (meaning mainboard issues) it's a side effect of the danger SPL.
Does anyone know if it is possible to flash hard SPL or reflash the danger SPL on a phone without bricking it?
maybe you're having the ribbon issue as described in the link below.

To the naked eye my ribbon cable seems to be alright, a bit dusty but alright. It doesn't have that white piece protecting it but other than a little dust it seems to be fine. Should I be able to see the problem?
Edit:
I'm not sure if this will help but I do seem to have better luck waking up the phone by sliding it open rather than by pressing a button.
Edit 2:
I've pretty much given up on this phone I'm just going to buy a Motorola Cliq when it comes out. Hopefully the wonderful people at XDA will be able to root in in a reasonable amount of time.
Does anyone want to buy an unlocked rooted white g1??? It works but have to play with the screen sometimes.

Nope. It's made by motorola and this XDA is a HTC only forum, many many people have asked Flar and others to add sub-forums for other popular smartphones and the answer is always no. You will have to find either a good motorola forum or one of the android forums because I can tell you with 100% certainty they won't support it here.
I am in the same boat as you though, my screen is all f'ed up it turns on when it pleases and sometimes it won't at all. I was able to send it to HTC for like $30 and they are fixing it and shipping it back so thats not a bad deal. Also, I would advise against the cliq as its gotten some pretty bad reviews (boygeniusreport.com) and the screen is a tad smaller then the G1. If you can hold out another month or so then get the sholes, also made by motorola. It will be for high end users where the cliq is entry level, sporting a 600-800mhz processor, 512mb ram/rom, 5mp camera, 3.7" screen, qwerty slider, 8gb sd (comes with), gps wifi bt and all the other good stuff. Will only cost 199 with a 2yr contract from verizon and if you prefer gsm it will be coming to att soon after it debuts on vzw.
Ya I was thinking of getting the sholes but I thought it was only going to appear on the Verizon network. I'm also contemplating whether I should just buy another g1. For awhile there it looked like support for the g1 would be dwindling. but with the two open-source android projects gaining momentum and both being focused primarily on the g1 it looks like the phone will have support for quite awhile still.
I'd love to be able to send it into HTC to get it repaired but I don't know if it's under warranty still (I bought the phone used) Any idea how much it would cost to get it repaired if it's not under warranty??
It should be, I think it is still less then a year old isn't it? You can call them and they will ask for the ESN, worst that happens is it's not under warranty but if it is then your all set.
Well it is also rooted and has a custom spl on it .. the danger one to be exact. Would I just have to throw on an unrooted rom or would I have to roll back the spl .. and if i have to roll back the spl would I be able to seeing as it is the "danger" spl.
And thank you for all your help so far, i really appreciate it.
this seems to be a more popular thread than mine, since you've actually gotten replies. I'm not trying to hijack it or anything, but I noticed tonight, since it was my first actual phone call, since my screen went screwy, that around the ear piece speaker gets REALLY hot immediately when I picked up the call.
I completely disassembled my phone, and put it back together. Thus reseating all the connections, and that didn't help mine at all.
Current state of mine is when the screen slider is closed, the display is jacked. Either just a full white screen, full black screen, or white with thin RGB (red, green, blue) lines horizontally across it. If I open the slider in that state, it stays the same, but if the screen is locked, and I slide it open, it displays fine. If the phone is locked, but the slider is open and I unlock the screen, it displays fine.
So I have no idea if it's the slider mechanism, a ribbon, or the board. I know mine is not under warranty, plus as soon as I cracked it, I voided the warranty.
Is it worth getting a full housing + slider from ebay for $55 and take the chance that it's the slider mechanism and not a ribbon or board? or go the extra $100-$150 and just get a completely new phone?
Hopefully this link doesn't violate the "no external links" policy, since it's to ebay, and not another HTC dev forum.
http://cgi.ebay.com/OEM-HTC-DREAM-B...ries?hash=item5ad1b3cd14&_trksid=p3286.c0.m14
Any thoughts would be appreciated, and might even help the fellow who started this thread.
Edit: When I close the screen 90% it switches to portrait, and when I tilt it, it goes to landscape and back just fine, but when I close it that last 10%, then it goes all funky.
really? nothing?

[Q] just purchased a g2 for $30. screen doesnt turn on

The phone definitely boots up because the lights on the buttons flash on then turn off after some time. The keyboard also lights up. You can tell the backlight turns on on the screen, but there is no picture.
Anyone have any idea about what I should do? Thinking about trying to restore to a stock Tom somehow tonight. Then I'm thinking about looking for screen replacements.
I was curious if anyone has had this issue before.
Update 07/14/11
So I got the screen and switched the old one out for the new one. This one also only has the backlight turning on, but I noticed when I put a part back on, there was a little bump in the middle of the phone. Haven't had a chance to fix it, but I noticed it's a piece hitting this rubber piece that seems to "transport" the sound for the mic from the bottom of the phone to the actual microphone module within the phone.
Removed that rubber piece, and I'll try installing it later. I was getting some blue and red visible in the middle of the phone. Anyone know what's wrong?

How sure are you it's the LCD screen? Replacement screens cost more than what I bought the phone for...lol
it's mostly the physical connection to the screen.
and on your note about it costing more than what you bought the phone for... there are tons of parts on the phone that will cost more than 30bucks. not much you can do about that since you got it non fully functional.

Never had to do it myself, but there is a cable connecting the two parts of the phone. That is usually where this problem originates from. It's not easy to fix though if your not familiar with fixing electronics from what i have seen.

I've taken apart my laptop completely and put it back together before. Completely as in taking the lcd off and different chips and wireless modules and stuff. I think it may be something I can handle. I'm going to take a look at it now. Restoring wont do me any good because not even the boot screen shows up.

So I completely tore apart the phone, got to the point where if I had another LCD screen, I could have easily switched it out. But I don't, so I just put it all back together. I really hope this new LCD will fix the issue. I really hope it's not some other motherboard issue. If all else fails, it goes up on eBay for $70-$100 as is for the phone. If I fix it, I just got myself a phone that goes for $200 used for only $57.
sure. goodluck with it. if you can do it then you're all set. good luck

Sorry. After some searching on eBay, I found some sellers selling it for a few dollars less than 30, e.g. 27.
But I decided to go with a seller who sold more than 200, who claims the screen is an OEM screen, and who is top rated. He sells his for $32. Which makes my phone $62 after all is said and done.
The housing has some scratches on the top and bottom though, which decreases the value a bit, but hey, if it works I'll probably keep it as a backup. Currently have the HD2, but I got a Vibrant with original box and accessories for $100, so I think I'm going to sell the HD2.
That was kinda off topic, sorry
LCD screen should be here by the 13th.
Updated OP
someone help =|
I don't own a G2 but I still think this could be a similar issue to what we get over here on the HTC Droid Incredible. First, what makes you believe its still a screen issue if it lit but just didn't throw picture? Usually thats the symptom of having the wrong recovery version for the device hardware version. Normally for us what happens is we will get somebody who is new and rooting for the first time and they'll end up flashing the wrong recovery or freak out because they don't realize the root process takes a little while and yank the cord. End result being exactly what you've explained above. Phone starts but no screen. So we end up having them do the ruu or a second option which we call a "blind install" where you drop whatever your p file(ours is PB31IMG.zip) so whatever it is for the G2 drop that on the SD and reboot to hboot and do the update process by simply knowing how long to wait between key presses and what keys to hit without useing the screen. Its a unique process and all very magical. Haven't lost a single Inc yet because of this issue.
Anyways bud just a thought...

It doesn't seem to be a ROM issue.
Update 7/18: Sold the G2 on eBay and still made a good lump of money. I was very happy, until another G2 popped up with the same exact issue. Got it for a steal as well, and I tried the OEM screen I got from eBay, and it was still having issues, and it seems to cause the phone to overheat while charging. Definitely a defective screen and someones getting a great deal on a decent condition G2 because I already took the payment after I figured it was the screen I got.
I'm going to try to get a replacement from the guy that sold it to me on eBay, but I already left him positive feedback thinking it was the phone's fault.
Will update probably late July or early August when all of this gets sorted out.
TL;DR: bought 2nd g2 with same issue, turns out replacement screen didn't work in the 2nd g2, too late to not sell the first g2, getting another replacement screen to fix 2nd g2. First g2 was in better condition though =|

Just installed the second screen that I ordered, and it works PERFECTLY. Phone is perfect nowwww yay. I can't use it right now though, previous owned put a lock pattern on the phone...
Wipe the system and the data and start over.

Replace lcd screen or motherboard?? Maybe? Maybe not??

Ok this one goes out to all you cool smart guys out there. I currently have two mt4g's. One is working perfectly fine with the "bad screen", as they call it, and the other is bricked, or no it has a failed pu is what someone told me, but it has the "good screen".
Anyway while just minding my own business on the internet one day I came across a video which shows you how to replace a lcd screen in a mytouch 4G! I was hooked. I could do this I said, it looked so easy! Sure you need some patience, which I got btw. So I was determined to do this, even ordered the tools from repairsuniverse. So about the fourth time watching the tutorial I began to wonder if it would be possible to just swap motherboards instead of disassembling all the way to the screen. Mostly because I still need a heat gun so i could remove the digitized then lcd screen.
So i guess my question is will swapping motherboards solve the pu problem in the mytouch with the good screen? And while I got you here has anyone ever replaced there lcd screen?? Is it worth it??

Yes, if you put the good motherboard in the case with good LCD, you'll get one good phone.
Thanks for the response! This will make the job so much easier

sorry to piggyback you post but i had a similar question....
a friend of mine is giving me their broken mytouch 4g. it was working perfect but then she dropped it on her kitchen tile (bottom right corner hit i'm told) and now it will not turn on at all.....no cracks or anything, just a scratch in the corner. she says she tried a new battery and tried plugging into AC but no lights, nothing.
i've taken apart enough phones so once I get it i'm not afraid to do some swapping of parts.
my question is, those of you who have worked on this model, any indication where you think would be the problem? i'm hoping the lcd/digitizer is fine since its not cracked but we'll see....and i figured maybe i would just need to do a motherboard swap worst case? is there any other components you think could be shot after the drop? from what i've been able to find its just the 1 main mother board , correct? (meaning there is not 2 parts)
thought MAYBE i'll get lucky after opening it up, and verifying all the cables that possible some cables got jarred loose and thats why it wont respond but not holding my breathe on that.
thanks for the help!

T9193 stopped working...

I´m so freaked out with my T9193, she stopped working... It has made me so sad, I really love my little jewel...
First I suffered the infamous unresponsive screen issue, but I had it repaired, actually it has a new OEM digitizer and LCD, but there is no output at all: the screen keeps blank (black). You can tell the phone is on because of the bright of the screen, the starting vibration an charging orange light...
I know it works because I Task29 it and flashed original shipped ROM (Telstra´s), and everything went ok as I could see in my laptop.
The main idea was to sell it as parts or very cheap in order to buy an Inspire 4G, but.... well you know what: it is a HD2! and even more, it is a T9193! Bought directly in Australia and shipped to my country... I feel like part of an elite jaja...
So, my question is, what do you think: an Inspire 4G or another T9193?....
Thnx
have you tried entering the bootloader? Maybe you should get it repaired. I suspect something is wrong with the motherboard. Alternatively, it could also be the case that the LCD is not working. I had the exact same problem with my Touch HD last time around. I sent it for repair(it was on warranty) and HTC changed the motherboard. Im sure repairing it is cheaper than getting a new HD2(unless you are going for a used one). Besides, you might wanna consider getting the evo 3d/galaxy s ii instead of the inspire 4g?(its your personal preference...but im just saying...) Hope your phone comes back alive in full glory! I know how it feels when your treasured device is in a coma. I experienced it with my Touch HD and i also experienced it with my HD2 recently, when it spun for 10 mins in the washing machine.But everything is ok and its breathing fire now!
Thanks for your comments kawshigan.
Actually I was able to flash it entering to bootloader (pressing volume down while turning on), but I couldn´t see it on the phone screen, so it seems to be just the LCD....I think...

well,if you were able to flash it,there is a high chance that the motherboard and the flash is working. So,it could be either the LCD or the BUS. But for the latter, if you send it to HTC for repair, they will still replace the whole motherboard regardless of a broken BUS or chipset...its just a way of making money...but if that can revive your HD2, you should go for it
