Blank / White screen but everything else works - MDA III, XDA III, PDA2k, 9090 ROM Development

After upgrading to WM6, every works perfectly. But then, it seemed randomly, the display is blank/ all white, but I can the phone is still functioning, because i can tap on the screen and get the tap sound. Soft reset and hard reset doesn't work. I'm doing the hard reset blindingly since the display is showing nothing, guessing the key push (i pressed record-camera 3x then mail button). I'm pretty sure it did the reset because after about 30 secs I get the beep that comes on when the screen is showing Tap to setup your device.
I figured it might be a loose lcd cable, but if go into the bootloader, power+record+reset. The display works fine! Showing Serial V 2.07.
I took apart the BA anyways and made sure the lcd cable is firmly attached. It didn't work.
Sometimes the phone would go back to normal randomly, or if I let the backup battery drain, but not always. When it goes back to normal, the clock is always reset to 2004 12:00 AM.
Can anyone help me? Is it possible to have a loose LCD connector which won't be able to show normal display, but can show the bootloader normally? Or is it caused by something else?
Here are other things about my BA that may or may not be related to the problem:
-Can't use DOC_Repart to resize storage, I'm getting the FL_IOCTL_FORMAT_PHYSICAL_DRIVE failed as described here http://forum.xda-developers.com/showthread.php?t=255585
-When upgrading the upgrade program can't detect my current OS version (showing blank under "Your device is about to be update from:"), but otherwise the upgrade works fine.
-I tried Helmi R0, PDA Viet , and xplode's 6.00 roms. They all give me the same problem
Thanks.

I am also experiencing the same issue... currently phone is at white scren, but using My Mobiler i can see my desktop and see that the phone is fully functional, just white screen so cant use...

Mine too. I can see the display working perfectly using SOTI pocket controller pro. So the phone seems to be functioning except for some reason the screen is showing all white screen.
cubangt, are using an extended battery or the standard battery that comes with the phone?

Have you tried flashing with a different rom??

Sorry, I fear my message won't be useful at all for you, but I'll post it just for the record. I hope you can find the solution to your problem anyway!
My BA now can't show anything but a white screen because of what I think is damage to the screen cable (while sliding the display the backlight goes on and off...).
But the cable is not loosely connected, it is sort of strongly bent at one point, and maybe some contacts got kind of cut. Now it does not work anymore, but some time ago switching it off and the on again used to do the trick: the display would be readable again (even though with annoying colours, stripes and so on). I don't think this is your case, but I'd like to warn the newbies like myself that they should care not to lose any piece while changing the LCD on their BA: I think I probably forgot about some sort of protection which could avoid damages to the cable in its movement.
As for the missing version number when upgrading, the same has always happened to me.. I think.
Ok, sorry for my English, I would have had some troubles with exposing these few silly things even in my mother tongue... bye... and good luck.

I tried 3 different WM6 roms. And if I remembered correctly this also problem also occurred for a brief while I downgraded to WM2003SE while trying to resize the storage(which failed).
Yeah I'm not sure if mine is a hardware problem, since I can always go into the bootloader and the display works fine there.
I have new info to add though. I found out I can reliably get rid of the problem by draining the backup battery. Now I have a new question, since draining the battery takes a while, is there a way to reset the phone as if the backup battery is emptied (and return my display to normal)? If I can find a way to simulate this, then I can actually use my phone again, even if I have to do this once a day.
Obviously soft reset doesn't work. And I don't wanna do a hard reset either. Maybe the experts here now what kind of data is reset when all batteries are completely drained.
Thanks for the help

hmmmm
quick thinking.....i was working on my phone tonight and came across this thread.....if not grounded properly it could be that you statically fried a component in the process?

Bought a Qtek 9000, first impressions & questions

I bought a Qtek 9000 a couple days ago and I'm pleasently surprised. I heard all the bad stories about the MDA PRO, O2 Exec, ... so I kind of feared the worst. But I took a chance and bought it anyway and the Qtek doesn't seem to be as bad as the other versions.
It does ring when I get called and the ring isn't late. I didn't notice any difference with my previous phone. So that's positive, I didn't change the ringtone on the other hand, so I don't have a large mp3 as ringtone.
Second, it is stable. Haven't had a crash, hangup, program error. Nor does it crash when I receive a SMS. I have received about 10 SMS'es though, not alot i know. The device is pretty snappy, I never have to wait a few seconds when opening programs or changing the screen-rotation. Also when I bring it back from standby, I don't have to wait at all...
I did a soft reset after setting the regional settings and the phone has been on for allmost 5 days. No major RAM issues, although the free RAM is shrinking, stopping applications in the memory-settings does free up some RAM, but not all. When I first booted the device I had just over 30MB free, and it has slowly decreased to about 18-19MB. I haven't installed any extra programmes on it.
So I might consider a soft reset when it reaches 10MB or so. But my question is, is a soft reset bad? Because you can't really shut the device off, you can only put it in sleep/standby. So rebooting it like a normal pc isn't possible. Does a soft reset damange any programs, settings... that's my main question.
Also, what's the best way to keep the battery in top-condition. Charge it when it's at 20% when the device tells you to charge it. Or charge it when you can, because it doesn't matter when you charge...
And one last thing, MSN Messenger doesn't draw the conversation window that well... Sometimes the part of the screen where your received/sent messages are shown is really small (about 3 lines high) and there is a large whitespace under the field where you type your message.
Thanks a lot to the guys at this forum for providing me with the most reliable info about the device, so I knew what I was getting.

PS: I ordered a Brando Screen Protector Plus, any comments, things I should know before I put it on the screen?
This is a good post to read first: http://forum.xda-developers.com/viewtopic.php?t=32218&start=150
Here you will have an is\dea of what to expect between a QTEC and an O2 NEW ROM version have to offer.
Thanks for the link, but I wasn't really looking for a new ROM. As I'm quite new to the Universal, I prefer getting to know the device itself better, before I start doing the more 'professional' things. Besides, I don't have any major issues with the Qtek ROM at the moment.
I just wanted to know a little more about soft-resetting the device and how to charge your battery for best longterm performance. Because I find the manual quite minimalistic.
To soft reset: YOU RETAIN YOUR SETTINGS.
1) Just press the small pin hole found at the back of the Universal right beside the USB plug.
To hard reset: YOU LOOSE YOUR CURRENT SETTINGS. BACK TO FACTORY SETTINGS.
A) Method One
1) Go to Start.
2) Go to Programs.
3) Go to Clear Storage.
4) Type in the code: 1234
5) Press YES.
6) Wait for the automatic reset.
B) Method Two
1) Press and hold the two keys with this mark (-) at the same time found at the top most part of the keyboard.
2) While pressing these 2 keys, press the pin hole found at the back of the Universal for 1 second.
3) You will notice a reset and a blank screen will appear.
4) It will prompt you to either press X or 0.
5) Just choose which one you prefer.

1) No, a reset both hard and soft does not damage your Universal. A soft reset to clear out the memory is good to speed up things better.
2) The best way is to leave it charging for more than 16 hours the first time. Unplug and use it till it drops to around 15% then charge it fully again, this time it does not need the 16 hours. Just wait for the green light indicating a full charge. After following these first two, just keep it plug-in before going to sleep at night making sure you got a full charge for the next morning.
3) I don't know about Brando's screen protector but I used Proporta's screen protector which included a wipe cloth and a screen spreader. I've had my screen protector on before I started even charging and using my phone. Another tip is to use a small peice of tape to take off some dust or specs that might have stuck on the screen before applying the screen protector. Sometimes even with the wipe there are still dust residues. You can also use the tape to clean the side of the screen protector that is going to stick on the screen.
Isn't a soft reset similar to pushing the reset button on your desktop? So couldn't you loose cached data that is in the RAM, because it wasn't written to ROM yet?

I had never lost any data after a soft reset. It free up unused memory that was being kept by the system for faster processing. Plus WM5 has persistent memory now. May be that was the difference?
So in fact, you can't shutdown a Qtek? You can put it in standby modus, but the phone is still working then. And resetting it, is just rebooting it. So if you want to take out your SIM card, you have to take the battery out while it is actually running?
You actually can turn you device off, with a little help of some small programs, like PsShutXP for example.
Hmm, thanks for the info. I will look into that one, but at the moment I'm still very hesitant to install any third party applications on my 6-days old precious.
One other question, does the led blink orange when you receive a SMS. Because now it doesn't, it blinks green, like normal. But I seem to remember the first I got it, it blinked orange. Or am I confused.
@emmerman
You are right you can lose data. I have lost emails and other users have reported loss of WEP keys etc. But I have never had this problem with Symbian devices.

Can anyone answer this one.
Go to Start>Settings>Sound and Notifications>Notifications Tab>Choose the event you wish to correct.
The changes in any settings never occurred on mine nor any type of freezes. Something I am glad about.
What I did when I first turned on my device, off from the box or right after a hard reset, was to go through those settings and made sure they are all configured the way I want them to notify me. This is the only difference I could possibly think of why others have disappearing settings on notifications.

Dead jamin

Hello all,
I have recently killed my Jamin. Im not sure whether it is permanent or not. Personally it looks like a rom failure with the video bois, but I am far from experienced with windows mobile#.
I have searched the forum and can not find anything similar.
(Story)
To cut a long story short, I picked up my Jamin while it was connected to my pc. Catching a gimps of WM5 and the battery fell out (while still connected to my vista pc). So it turns off and I put the battery back in and turned it back on.
(What does work)
This is kind of hard to explain, but from what gather, everything seems to be running fine except the screen. Basically it still syncs up (can access files) and the Bluetooth led turns on after a minutes or how ever long it takes
(Problem)
The problem is that the screen is doing something weird (This is the hard part to explain). I do not get anything out of it even the "htc" pic at the start.
It has these blue horizontal lines about a pixel wide running down the screen. They change like the screen is trying to display different things but it is as if it does not know how to use the screen.
Im thinking re-install the rom? But I do not want to make things harder for myself if I am wrong.
Any help would be greatly appreciated.
Tryed Flashing.
Well If anyone is interested, I tried Re flashing and I still get the same problem. My next PDA will not be an Imate, too many problems.

Touch Response Problem

I have a Sprint Touch [Vogue]. It has served me very well up until recently.
One day, I was using my phone normally when the battery died. No big deal right?
Well, I charge my phone and reboot it. For some reason, Windows is EXTREMELY slow and unresponsive. I figure that something vital had been corrupted by the battery's death, and that it was nothing that a hard reset couldn't fix.
I performed a hard reset.
I let the utilities for the first boot run to customize the phone. Everything seemed pretty much normal. I configured my settings, re-added my contacts, etc. Then I turned the screen off [with the power button].
I turn it back on later to do something. I touch the screen. It immediately and accurately detects the touch's location, but it continues detecting a touch. For 20-30 seconds, after the input has stopped.
It was strange, so I soft reset the device. It booted, with the same problem. So I performed another hard reset. I did some configuration [the response acting normal at this point], and then turned the screen off. Turning it back on brought the same problem back.
This problem still exists on my phone, even after numerous hard resets and even ROM flashes.
A better description of the problem: When the device is first turned back on [meaning brought out of standby], its touch response is messed up. It will immediately and accurately detect any touch input, but it will continue to detect the input for up to 30 seconds AFTER it has been released, as if you were holding it the whole time.
WHY is this???? My phone is almost unusable because of this!!!! I can still place/ receive calls, using the navigation buttons and the red and green buttons. But the touch response is screwed!
Can someone please shed some light on this problem I'm having?
Phone specs: Windows Mobile 6.1, HTC / Sprint customized. Minimal third party software is currently installed.
[I've already determined that third party software is not the problem, because i haven't installed any!]
Possible solution
Hi,
today I experienced something similar to your description - no touch response when I tried to pickup a call. The strange thing is that last night everything was working and no settings were modified nor programs were added/removed. The screen suddenly 'died'. At the moment I am using it through a program MyMobiler which brings the mobile display to the PC and I can use the mouse to control the phone (it is like VNC for the phone screen, the phone is connected with ActiveSync).
This is temporary solution untill I finish my backups of files, programs, settings. I didnot performed hard reset yet, hope this will solve my problem
In the following link there is a 'magical' solution - to remove the screen protector:
http://www.htcwiki.com/thread/1112981/LCD+or+Touch+screen+not+working
P.S. I had removed the screen protector and voilá - the screen is now touch responsive. The root cause of the problem obviously is the dust between the screen and the protector which results in constant screen pressing - and as a result no accepting my finger presses.
I hope this will work for you and others with similar problem.
I had a similar experience with an old Vogue.....In my case, there was no battery death precursor, but it just started acting up. Not too long thereafter, I noticed the screen/digitizer was forming what looked like an air bubble between the digitizer and the LCD on one place of the screen. The screen was becoming defective. I eventually had to buy another Vogue from a friend who didn't have a clue of the 6900's potential, and didn't want his anymore, so I got it cheap.
Sounds like your screen/digitizer may be on it's last leg.

display turned white

hi all
my htc touch elf (P3450) display turned to white with black patch at one place & some lines all of a sudden. it was working all fine. i was charging when a call came. i disconnected recieved the call. after that the screen turned white
Tried restarting but no result.
I can hear the notification of a message coming. but no ringing tone when i tried calling from other number
Please bail me out.
regards
Hardreset could be the solution
not resolved
i cannot see anything on the screen except white screen with black patch.
i tried hard reset with imaginary screen but not resolved
i see no visible screen cracks
how to check if screen is crack?
It may be that the LCD is cracked, thats what it sounds like to me, anyways. Check the connector as well though to make sure it is all connected correctly.
The white with black patch does sound broken to me though (Sorry!)
Stu
Hi Stu, I just received my friend's ELF. His display turn white, but the device still be able to receive phone call. trying to enter bootloader, all I get is white screen with some black-horizontal-thin lines. Tried to hard reset, now it seems the device is on phone setup position so I can not get anything.
Is this LCD issue? Could it be broken? FYI, before this happen, there's already one dead pixel on the screen.
BTW...is it possible that upgrading to cooked ROM can bring LCD broken? may be, unsuitable ROM?
regards,
Bom81
Not sure if flashing a cooked rom would kill the screen - although I would say thats very unlikey.
It does sound like the sceen is broken, theres one way to find out - If you don't mind giving it a go - you could always try your screen quickly in his phone - I'd imagine you're fairly familiar with the internals by now
(I do have a spare screen laying around now - JTAG is no longer able to pick up my bricked elf at all - full battery etc how I was doing it no longer works - guess it is dead for sure now!)

Hahaha..LOL, Today I did want to put my LCD on my friend's elf. but I forgot to bring the opening tools to my office. guess I'll do it tomorrow and see how it goes. I'll let you know after my experiment with this thing.
A little bit Of Topic on this thread, I think so, your device has problem
so even the JTAG method will not be able to connect to the processor. Too bad you're in england, otherwise, the spare screen could be very useful here. LOL
UPDATE
ok..confirm the LCD is broken. I've changed the LCD with mine, and the device is working fine. i guess the dead pixel is the cause of the problem.
Should be able to find one cheap enough on ebay - I do seem to find it cheaper to buy another faulty one (maybe even bricked) as long as the screen is working
Need help on my HTC Touch
Hi Guys,
I really need your help badly. I have an HTC Touch (Elfin), I presume (128/256MB). The problem is i have downloaded the official windows mobile 6.1 rom and extracted the .exe file using Winrar. After which, i copied all the files to the sd card and renamed the .nbh file to ELF0IMG as instructed in the forum.
I put back the sd card and pressed the camera button and the power button at the same time. When it booted up it says reading from SD card and I can see that it is extracting the roms and ext roms. Afterwhich, there was a progress bar and then soon after a while screen turned to blue and then white. Currently now, as I am tying this the screen is still white. Please advise me asap in what to do? Thank you very much.

Ur display screen has been broke as simple as that..
Ok. Here is the thing.
I've droped my phone down, straight on the screen, no problems. 5 minutes later, when my brother was trying to play on it the screen turned white, with no stripes.
After 1 month i even forgot i had an htc, found it in my office drawer, and i thought of reinstalling the rom. But before that i pushed very hard on the screen, i took the battery out, pushed it in the battery space and after i started it worked like a charm.

TMobile S8 works fine, except the screen won't turn on

My brothers TMobile S8 screen randomly stopped working. It has no signs of damage anywhere as well. Weirdly, I managed to get the screen to go on one time by pressing some button combos to try to follow a guide to get it into recovery to factory reset it. Upon the phone booting, the battery had 3% and when I went to show him, it was dead. Now after letting it charge, the screen does not work once again and I can't seem to get it to come on in the same way it did before, the bright blue recovery screen.
Is there any software I can use to just attach the phone to it and factory reset it? I mean, I've seen bad phone screens before that have still had images show up on them, even if heavily damaged physically or it no longer responding to touch and showing dim lights. But this one simply doesn't turn on, except the one random time it did, and it was perfectly fine, showed no sign of damage. Any thoughts would be greatly helpful
Is the battery known to be good?
If not replace it. The system will not boot if there's not enough current. It takes a fair amount of power to boot up. A charger can't provide enough to do so...
It boots up fine, I can hear the initial TMobile boot audio as well as the notification sound the phone makes when it gets to the lock screen. I also had it stop charging @80% not too long after buying the phone on release, with some custom ROM I installed. Ofc its a possibility its battery related, since I can't see anything on it, but it was taken care than the average person I am sure
With a custom rom all bets are off. Makes troubleshooting much harder. Possible rootkit.
Firmware and malware aside if it's booting but no display, possible loose ribbon connector, failed display or mobo. That's assuming the battery is good...
Well I did disable/uninstall Superuser from the phone, and I used it for a couple years before giving it to my brother to use. That is a good point about the cable, I will search for images, maybe I can squeeze a few spots to just see what happens

Sometimes just reseting a connector is all it takes. Those are low voltage lines and a perfect contact is needed.
If the battery is more then 2-3 yo it's probably at the end of its usable service life.
Thanks for the input, I will open it up if nothing else works and I will report back if it helps
