Hey everyone,
Firstly this is my first post and so I am not quite sure whether I am posting in the right place. Accept my apologies if I have made a mistake. I own a Htc Tytn which I purchased this January 2007. I read in several forums that some users are experiencing certain problems with the device like screen allignment etc. I was very glad to find out thart my device was a very stable one. Surprisingly it never froze. I did perform some soft resets at times just to ensure everything stays all right. I also did not have any keyboard or allighnment issue. Today when I was speaking on the phone suddenly my Tytn shut down. When I restarted it the screen went white. Firstly I tried performing a soft reset which didn't work and then a hard reset which didn't work as well. Then i thought of entering the bootloader mode so that I can install the ROM again but it wouldn't go into the boot loader mode ( I did press the right sequence of buttons for the hard, soft reset and for entering bootloader mode). Even the htc logo doesn't appear. Whenever the power button is pressed the screen goes white. Also whenever I tried the different reset and tried entering bootloader mode the screen went white as well. My device had almost full charge when this happened. Also one more thing, as the screen goes white the green button( send/ receive)button blinks( weird!!!!) but the red button is not lit and doesn't blink at all. Lastly I think I have made it clear that I was not trying to upgrade the ROM or anything when this disaster happened. I WOULD reaaallly appreciate if somebody could help me sort this problem out with my Tytn before I am forced to send this device back to HTC for repair( which I don't want to). Thanks everyone.
Check the TyTn Wiki:

There's a section in there on the solid white screen, phone doesn't boot. I think it's in the "Common Upgrade Problems" section but the advice there may be applicable to your situation. Good luck!
ok guys actually two problems here:
1. my wizard works fin no problems at all until i go to use the keyboard for txting or emailing, sometimes its ok other times the screen goues fuzzy and then a lot of lines appear?? any ideas is it hardware or software problem??
2. ive recently tried flashing a new rom to my pda actually a few bu everytime i flash its the same rom that comes up as before ive hard reset after flashing also soft rest but its still the same rom any ideas?
Have you CID unlocked your device?
I'm having the exact same problem with my keyboard, although it doesn't *only* happen with the keyboard. Every now and then--more and more often now--the device just stops responding for five or ten seconds, and then the lines appear, and the screen fades completely white after a few more seconds. Sometimes it reboots itself, but not always. It never responds to any input after that.
It really sounds like a hardware problem to me, but I have no idea what to do to fix it. A friend of mine who is very much into (read: addicted to) ROM flashing said that a re-flash would solve the problem, and suggested I go back to an official ROM first, just to be safe. I did exactly that, and it did nothing at all to help the symptoms. I've gone so far as to start using a Blackjack II for the moment, because I can't deal with my phone locking up randomly all the time. Any help would be very appreciated.
I too have a similar problem, except its just with my screen that occassionally i get lines down the screen then it fades to white, putting it into standby and back on again gets the screen back. My device still responds however.
Sounds like hardware issue. I have come across quite a few threads with similar problems
yes my device is cid unlocked i used to have no problem flashing roms but now it just doesnt happen all it does it resets the standard rom and all the tmobile gumf loads up
**also does anyone know how to get rid of the tmobile stuff permanently?
Hi,
I just bought a HTC HD 2, French and unlocked version.
I have a big issue with my phone: The device start, I use it 10 Minutes then lock it (stand by).
When I push the wake up button, the phone seem to work but the sreen turn ON and stay Black... By saying the screen is ON, I talking about the backlight
I tried a Hrad reset several times but the screen is black at boot.
Can this black screen issue is caused by a software problem? Beacuse the screen work well for some minutes...
Thanks for your answers
If there isn't even a boot loader splash screen i would say its something major. If you have only just got it then i would take it back or have you flashed a custom rom or used goldcard to flash a different stock rom. If you haven't I would take it back.
I have had my HD2 for about three weeks now. It came with 1.43, but have later on upgraded to 1.48 and now Im running 1.61. Two days ago I started to encounter a really annoying problem.
When I wake up the screen and slide the button the home screen appear but after one second, the screen turns off back to lock. Then I can unlock again, and again one second later the screen is off and back to lock. This often continues until I remove the battery.
Have you experienced the same problem?
Optiknerd, Thanks for your answer. I called UPS on 24 December, they're coming today.
I was just hopping there was a solution...'cause it's hard to quit this phone....
I never installed a modified ROM. The firt black screen apaired 10min after my first use. Even at boot I can't see anything and I have to Push ON/OFF more than 20 times to wake the screen up....

Did you install any software when the phone was working okay?
Also, when you get the black screen, hold down the power button and see if you get anything. I've had mine go black screen on me and that brought up the quick list. I selected lock and it worked fine after that.
See this please http://forum.xda-developers.com/showthread.php?t=606093, let me know if you have the same problem as me,cuz I havefigured out a solution and it works for me at least 2 days.

Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method
CM7.1 RC1
Clockwork Recovery
Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

A. They don't care if its rooted.
B. You can root stock Gingerbread.
Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...

I found on ebay: HTC-Desire-Z-T-Mobile-G2-A7272-Slide-Flex-Cable-Ribbon
or I found also with the chassis for a bit more.
Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.
