Not functioning correctly after replacing broken screen. Help! - JAMin, XDA Neo, S200 General

A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.

I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.

SOS - Hermes works fine just that there is NO screen!

Really need help here,
My hermes suddenly decided that visuals are no longer needed.
That means the screens stays off all the time (yes even in bootloader mode).
It works, receive calls and flashes roms but in no situation can I see anything on the screen (pitch black screen).
I've got no warranty so I took it apart and checked each cable and connector - no issues were seen. I tried changing SPL-s, RUU, Roms all worked but left my tytn with that black screen.
Did anyone see this happen or has any advice?
This sucks big time :-(
No one? Oh man, I guess it's dead then :-(
Last bump before giving up and throwing it away - please?
send it to me if your gonna throw it away : - 0
I've given up on mine as well. It has white screen though. Where do I dump this thing?
If it is out of warrenty, I would take it apart as is sounds like the hardware, check the connections to the LCD. Does the backlight still work, or if you put it in strong sunlight, can you see the LCD working?
My Hermes had a white screen also. I found that if I squeeze the bottom right hand corner whilst resetting it would sometimes work. It seems there is a chip on the switch board that needs the right ammount of pressure on it. I think it was a design flaw as the herm200 and 300 are different. If applying pressure works and you are confident enough take the hermes apart and put a couple of small pieces of plastic or paper between the front buttons and the small square chip on the switch board. This worked for me.
The service guide is available if you google. Let me know if you need more info.
As for the black screen that sounds more serious sorry not seen that one.
what are you guys willing to sell your pdas for? Mine fell in a puddle and i need one for parts. The white screen might be fixable the first couple of times but then it dies off for good, the black screen i've never heard of.
So if you want to sell for a reasonably cheap price let me know, i can buy a new keypad online for $50. So around there would be nice!

I just tested this on mine and actually got some results.
mines the opposite though, it will NOT work with any pressure. I left all the screws loose for that board under the buttons, and left the LCD assemble screws out on that end and it works, But if I press the keys it whites out again and won't come back until I repeat the dis-assemble/re-assemble
I had a similar problem but this was after someone dropped mine on the floor. The screen would just be white screen, while everything worked. If I pressed the bottom right of the phone it would sometimes come on and stay on for a little while but would eventually always go to white screen.
I did manage to use the phone but had use a program called Net Control which allowed me to control the phone over WIFI with the phone screen shown on the PC. Got the phone replaced in the end by the people who dropped it.
i got the flex cable and my phone still has the white screen problem....wtf///

Cracked LCD or whitesreen?

I have read a few posts about the white screen issue and some seem to pertain to my problem and others don't. My screen is white 100% of the time from power on to power off. So I can't seen anything when it first boots or comes out of standby mode or any thing else. The only way that I can get the screen to be anything but white, is to hold it in my left hand with the keyboard slider bottom left corner of the phone pushed up against the base of my thumb muscle and my other fingers pushing on the bottom right corner or the phone on the screen slider. Sometimes if I hit it in the bottom right corner then squeeze it I can get it to work without tiring myself out from squeezing after 1 minute.
Seems to be a pressure and angle thing i think. The phone has been dropped on more than one occasion. Ten tops. Sometimes when I squeeze it i get lines from left to right, then fade to white.
If I put the phone on 65-90 degree angle from my eyes I can see a little black mark at the top of the screen under the C of HTC. That is what had me thinking that it was a cracked LCD.
Any help would be greatly appreciated. Phone is still under warranty, but would rather not be without it for the 6 -8 weeks I was told it would take, only to find out it was a cracked lcd and they won't fix it.
I believe you have to open it. Try to connect every single connection again.
I Had This
I had this problem when i dropped my Vario 2 the screen cracked and was all white, when i went on ebay and bought a new screen I took the vario 2 apart and replaced the screen BUT the ribon connector that plugs into the board was not quite in so when i re-assembled it i just got power and white screen.
There are a couple of little lugs on the ribon cable and i though that once they were butted up to the connector on the board that it was in properly. BUT the lugs actually needed to be pushed that little bit further and slide under part of the connector. BANG it worked fine.

Either send back and keep warranty or try the several solutions posted. I myself am pretty sure I found the correct solution and I posted it in the appropriate thread.
Thanks guys, I think I'm going to try my luck with sending it in. Will probably add a link to the main whitesrceen thread so hopefully I get no hassles. Will post back When I get it back.
I had a similar problem and voided my warranty because I don't have a spare device... anyway, here is where I found my solution.. http://forum.xda-developers.com/showthread.php?t=321163
Good Luck... My phone is still working fine....

Touchscreen doesn't work anymore

Well, plain and simple is that my touchscreen doesn't response to any touch reponse but the screen is working and everything else
I recently bought a white G1 housing kit on ebay and decided to take the risk of opening up my G1 to replace the housing of my black G1 to the white one, but turns out the white case for the screen / menu buttons arent correct so i scraped those and just changed the keyboard and menu button keys to white and put everything back together properly and exam each part and etc.
so i put everything back together and turn on the g1 everything works fine but the touchscreen doesn't work, is there anyway i can fix this?
life is hard using the G1 without a working touchscreen lol
thanks again and i don't think my screen is defective just wondering why it doesn't reponse to my touch
thanks
Once I was walking around in the heat with my G1 in my BDU pocket for like 4 hours, and it obviously got really humid in my pocket, and my touchscreen stopped responding. I let the phone just sit off for a while and after about an hour sitting in my room, it started working again. But I've had several instances where the touch screen has been less responsive/not responsive.
My guess based off my experience would be that some ambient moisture may have gotten into the phone when you opened it up. How long has it been since you put it back together?
Any update on this?
you said you had 2 g1s, right? so take the phone apart again and replace the touch screen.
the touch screen is separate from the LCD, so that wont affect it.

White screen all the time. What should I buy?

Hello,
for first I've already read some topic covering the white screen problem. I have the white screen every time on my Hermes since booted. Going into bootloader also shows white screen. I don't see any signs of misalignment.
I've already taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws by it. I see there's nothing else I can fix without replacing any parts (or am I wrong?) What should I buy? Do you think that the actual screen may be faulty? Or maybe the flex is damaged and I should buy it? (well I think that some chip is connected to flex so I don't know if it can be replaced anyway). My main question is: if the screen is all white, is it possible that the actual screen be faulty?
It could be a number of things which could amount to $$$$ by throwing parts at the phone - may be cheaper to just buy another. Before the completely all white screen did you have occasional white screens with increasing frequency? First try some of the fixes for correcting whitescreens - pressure on the dpad - etc. If you still get nothing the chip could have come loose - but who knows?!!!! Need some more information - history etc.
Unfortunately don't know the history... bought cheap off ebay hoping it can be easily fixed already ordered the screen, if no luck, will send as spares/repair in my country - should earn something anyway.
i have a fault with mine some times (well a lot now) when i open it or close it all the way i get a funny fuzzing on the screen and some times it just ends up going black, move it back and forth a bit and the screen collour is inverted. i have to press the power button twice once for off then back on and it stays normal collours till u move the screen again. is this called white screen?
Not really - yours should be an easy fix. Seems like the flex cable is either loose or cracked slightly. It only occurs when you slide the keyboard out right? Any problems with the front keypad - with the unit closed?

*POSSIBLE* fix for Newton Rings

Okay, so lately my screen's becoming more and more out of alignment. I've basically had to use the black frame on the right hand side of the phone to click anything on the right that needed to be clicked.
Then last night my phone froze while rebooting, wouldn't show the boot animation, just the welcomehead image and froze there. Needless to say I thought something's up. Long story short I checked everything that there is to check and ended up having to hard-reset.
While flipping my phone around through all possible dimensions, i noticed the oily looking stain that is the well-known Newtons Rings problem.
I wasn't willing to be without my beloved Blackstone for a warranty repair and was about to jump on eBay to look for a replacement screen and digitizer, when I remembered something that fixed the touch screen in my old Sony Ericsson P900. So here's what I did that has so far fixed my newtons rings and returned the more soft-touch feel of the screen.
WARNING do the following at your own risk!!! I will not be held responsible for you killing your already dead, Newton Ringed screen
* First, be sure you have a screen protector on. I have a feeling that not having the protector on will damage the screen further.
* Grab your trusty $2 Bic cigarette lighter.
* Hold your phone on such an angle that the oily-looking Newtons Rings are visible. The right amount of light, from the right angle will show them up like the dog's proverbials.
* Ignite the lighter and hold it so the flame is lightly touching the area that has the problem.
--You won't see the rings disappear, more like they will start moving--
* Move the ignited lighter until you have moved, or removed, the oily looking problem areas.
EDIT 29-07-2010:
* Try not to hold the lighter too close for too long, otherwise you may end up needing a new screen protector
NOTE: I do NOT guarantee this will work for you, however, in my particular case, the rings appear to have gone, the screen is now once again soft to touch and the alignment seems MUCH better. It has now been approximately 12 hours since I did this, and so far, so good. All problems are still gone, no visible rings, and the screen is still far more responsive, almost like new.
Newton Rings
So did it fix the issue permanently?
Well, it sort of has succeeded. While my screen still has a huge patch of Newtons Rings (approximately an inch and a half long, by about three quarters of an inch across, they came back after about a month or two) the screen is still functioning, the "soft touch" I mentioned in my first post has nearly dicipated, but it still works. Every now and then the screen will act as if it's stuck down towards the bottom of the screen, but simply rubbing it with a cloth and some mild pressure (just like when I clean it) is enough to bring the screen back to working.
At the very least, it has given me time to save up for a new screen. But I won't be replacing it until such time as the next big change pops up in WM6.5 builds and I cook a new ROM. At this point I'll be completely disassmbling the whole phone for a thorough cleaning. While I'm at it I might as well replace the screen and keep the N.R one for a backup.
To put it simply, the screen is still working and I have no need to replace it as yet.
P.S I'm no longer using a screen protector, I don't care if it gets scratched up now, because it will be replaced, but not until it 100% needs it. I will however put a new screen protector on, if I have to do the lighter trick again.
Thanks Swarvey, got newton rings and helped remove the with the lighter, however i will hav to replace the screen protector.
Cool, glad to hear it wasn't just a once-off that it worked.
I never burned/melted my protector by doing it, but you might have different results with the much higher temperature you subjected yours to.
Keep us posted as to how well it works for you.
In fact I know a less dangerous way to eliminate those rings. I was exactly in the same situation with my HTC Touch HD. I just used some Scotch tapes on the screen, pull the screen to me , and with a lot of patience, everything as desapeared.
It works again !!
