No screen Backlight - G1 General

OK i'm playing with a G1 and the screen backlight seems to have went out on it. Initially i thought it was a bad flash because i was able to boot but it had some problems. oh yeah to see the screen i use a mag light aimed at it to navigate etc.... anyway i finally was able to get it to reset so i reset it. still no backlight. finally i unrooted/reset to factory default via these instructions at google and still no backlight. any suggestions as to what to test next it almost seems like it is either a flexcable which i do not think it is because if it were i don't believe any of the screen would work. or a bad lcd that needs replaced.
any help would be greatly appreciated.
thanks

I had this happen for a few days intermittantly, i just joceled the phone a bit and it got working

tried messing with it and such, no luck really. any other ideas?
thanks

You could get a really bright flashlight I bet that would work.

Help With 8525!?!?!?!

So Yesterday for no reason at all my 8525's screen went white. i thought it had frozen or some thing but it didn't snap out of it. I pressed the ok button on the side and could hear noise. I decided to restart. Nothing. Did this like 7 times. Finally I let it sit without the battery for like an hour. I worked but the colors were all messed up. Reset and it worked fine. So i set my alarm went to sleep and woke this morning to an email and a white screen. Turning it on and off a couple of times did it and I was already frustrated.
Then I read on a forum about Activesync automatically opening throughout the day to try and connect. So I tweaked that to manual connections. Still the same. So I decided to take advantage of the warranty but I needed to set back my rom b/c as you already know, it voids it. Also thinking that re-flashing might get rid of whatever it was failing in. No, still the same, and now worse. As or an hour ago, my navigation pad doesn't work either. It actually works for about a second when I turn it on and then after I press anything on the pad or surrounding buttons, it's gone.
I really would like to fix it myself at least for now and use the warranty exchange at about 11 months but if theres nothing I can do, I guess I can go get a new one. Also, I don't know if it has anything to do with it, but I downloaded Google Maps to my phone yesterday on the road (through 3G) and that was the only new program installed( I think it mightve been this).
Has this happened to anyone else?
Any help would be much appreciated. I hope I explained enough for anyone to respond. Thank you in advance to anyone with anything really.
Actually if you do a search under white screen you'll find many entries. Any attempt to fix yourself will void the warranty. If you are lucky it may only be the d-pad connector that is loose. This it is possible to check yourself but if have a warranty then I suggesting using it.
Otherwise see the link to my site in my signature for dismantling and service manual guides.

Thanks. You know I think I will take advantage of the warranty sometime this week. I don't know what happened. But I'm to update my situation. It now seems as though my directional pad seems to be the problem. it glitches on and off and using it sometimes creates the fade-out to white screen. I have to let it go to standby on its own to get my screen back or play around turning it on and off for a bit.
Also, once i re-installed me ATT rom with no applications, my screen seems to be off. I have a 1/32th sliver of the bottom of the screen at the top of my touchscreen. Even in landscape it shows my scroll bar and everything. I didn't even drop it but it is now slightly skewed down. Any input on this?
I also found this website talking about the same problem having with and unorthodox solution (which I tried to no avail). Here's the link if anyone want to check this out. http://www.htcwiki.com/page/AT&T+8525+Display+issues:+Display+is+dim,+blank,+white,+has+lines,+etc.?t=anon
Anyways, I'm gonna call ATT about this see if they can help but I think I will replace, I just didn't want to so soon.
Thanks again for the quick answer.

Everything they suggest on that site you have tried I guess, the soft and hard resets etc.
I agree with you about the d-pad (directional buttons). Those with this problem often report that the d-pad or it's connector are re;lated to this issue.
Pleased you have chosen the warranty route. You see evn if you opened it up, it can work for a short while and then return again. Also push hard for replacement not repair. They may do this automatically but if not try to persuade them. The reason is that quite a few folks have reported that even after an HTC repair the problem can come back. Actually I think there may be more than one physical cause of this issue and sorting one thing does not mean it won't come back via another route.
The good news is, if you get a good one as I did on the second attempt, I never had white screen or alignment issues - despite heavy use.
Mike
Once again, thank you Mike for all your input. I will be issuing an order for replacement instead of repair. Being at work all day today I've seen that it hasn't "whited' out, if you will, but has actually kept working. Ever so often the d-pad goes but comes back in a few seconds. It may be due to the WM6 i had on it so for now i will keep the original ATT upgrade of WM5 and try to hold off on the warranty as long as I can before it expires. That way I can enjoy a healthy new 8525 longer.
For now I will keep looking around in these forums and see if there ever is a solid solution. Thanks again, and good luck with all.

Screen "vibration" (flicking?)

Hi all,
as my signature says... yes, I sent my X1 to repair (cracks, as always). When I got it back, it seems to be perfect. Outside. Switched it on and it seemed ok.
As soon as I came back home, I noticed that the lower part of the screen "vibrates" (I can not define it in a better way... I suppose the right verb is "to flick"). At sunlight I did not noticed it, but at home and in the dark it is really really visible (and annoying, on a 600€ brand new phone).
Does someone ever had the same issue? or does someone know how to solve it (apart from sending it again to repair).
Thanks!
P.S.: searched the thread and foud nothing. Searched in google and just came up with a "refresh" problem, that does not apply to our X1... or can we change the refresh rate?!
I did once experience what I believe was the same issue, the flickering screen. The problem was still there after a soft reset and power cycle, but then after leaving the phone for a few minutes it turned back to normal.
Unfortunately I don't think I be of much help here as I don't recall doing anything special to get the screen back to normal.

HELP desire z screen wont turn on

Hi everyone, I got my desireZ back in November and it has been working perfect ever since, i have it rooted using VISIONary and everything was perfect until today. The phone was in my pocket and i was lsning to music, i looked at my phone and all i saw was a white line going from the top of the screen to the bottom, i pressed the power button to turn of the screen, then i pressed it again and now all I see is a black screen with the back light on.
I have tried to soft reset the phone, took out the battery sim card and left the phone for a while, came back turned it on and still the same thing black screen with the back light on... The touch screen works fine i still hear the phone receiving txt msges and emails, i can even receive phone calls, and answer them by sliding my finger across the screen like usual.
I am trying to do a hard reset of the phone but i can't do that cause even when i turn on the phone while holding the volume down key i still dont see anything on the screen
any help would be appreciated.
EDIT - after trying to open the keyboard a couple of times, now the screen turns on white... when i press the power button to turn of the screen and turn it back i see a fading effect where the screen slowly turn on from left to right (fades from black to white) and then stays white till i press the power button again....
Since i have rooted my phone, i dont belive i can take it to bell to fix it the way it is... and since i can't see the screen to perform a hard reset to remove the root (i dont have s-off) ... does anyone know of another method for doing this? maybe with connecting to a computer?

There is another thread on the forums about someone having the same issue. I believe there is a solution using adb on your PC to connect to the phone.
Not sure how 'tight' your service provider is, but if the screen is dead, and you are still under your warranty period, they may simply swap the device for you after doing some 'basic' tests and dump it into the bucket that goes back to the factory for refurb. The fact that it is rooted won't be discovered until much later, if ever, so it may not be an issue.
Good luck!

Any idea on the location of this thread, can't find it anywhere.
I am suffering the exact symptoms as the OP with my Desire Z which is rooted with visionary rom flashed - I would really like to know how to use adb to resolve this !

[Q] My screen is not responding any touch input

My Nook Color is brand new. It was 1.2 and i used manual rooter 4.6. It was working fine until today. Now it does not responds any touch on the screen. I tried restarting, shut down and power on several times without any luck. Does any one knows this problem...
Had that happen a couple of times after got some greasy fingers or other such stuff on the screen. Power down and give it a real good wipe down. Get right up to the edges and everything. Clean it so you can't see any blemishes at all and try powering up again.
Only suggestion I got...good luck!
Unfortunately i tried that couple of times... but thanks any way... i hope someone has other ideas...
A new dimension on this problem
I opened my nook color. I disconnect touch screens connections. Then assembeled it again. Screen started to work for a while. Now it is dead again. I couldn't get the problem but it is probably a hardware issue. Does anyone nows anything about it.
Might try backing up your data and reflashing.
I tried it already.
it doesn't sound like a screen calibration thing but more of a hardware thing. if i was you i would re-root and reset to factory setting and take it back to B&N and get a new one. good luck
Yes. If i was in States... A friend of mine bought it for me from states and it is going to be a real pain in the ass to send it to another friend to change it...

Phone works but backlight of the screen doesn't

Hello,
As you can see my issue is related to the screen... backlight always worked until some days ago where it failed somehow.
It started to fail when I flashed Stock Kitkat with the recovery but I don't think that it could be related...
My question is simple, did anyone faced this issue and resolved it?
My guess is that it has to be repaired but if there is a small chance it can be repaired from my side without opening it I'm willing to try it, otherwise it goes to reparation
[EDIT]
Apart from this issue the phone is working just fine, I mean it boots correctly, can enter in download/factory reset mode if I want too.
The only thing is if I adjust the brightness on the phone from Android nothing change, the phone is still dark and can hardly see what's in the screen.
[/EDIT]
Thanks in advance!
