i am faced with the same issue too. hope someone is able to assist.

This sounds suspiciously like the DSOD problem that plagued the Sprint and Verizon 6700 Units. DSOD = Dark Screen of Death After much research the problem was found to be caused by the SD Card. More specifically having programs installed to the SD card, it seemed power managment was not properly implemented or something and often times when something was accessed on the SD card while the unit was in suspend it would exhibit the same symptoms you described.
There is a long forum post about it here.
http://pdaphonehome.com/forums/ppc-6700-xv6700/79197-regedit-i-have-made-make-6700-more-stable.html

my screen washes out white sometimes

Mine will turn the backlight off randomly when I start to enter a text message or an email... it turns back on after I press a button however.

DSOD? Yikes sounds terminal! As for the SD issue, the screen went dark after a hard reset / rom reflash with no sd or sim card in.
I'm going to send it back to HTC Europe, hopefully they'll swap it? Anyone had any experience with an RMA to these peeps?
Thanks

SOD and White Out Screen
Guys:
Let me share this with all. I got the white out screen of death on my TyTN about a month after I bought it. I would take the unit out of sleep, it would momentarily flash the good screen then fade to white, then black. I thought this was a software issue with something I had installed, so I re flashed the phone a couple of times and the problem persisted. This problem is an issue that needs repair, I'm afraid. I tried contacting HTC about this through their website and got no response. I guess they don't talk to peons like us. So, a week later, I contacted the place where I bought it in the USA, networkingrus.com, since it was still under warranty and they gladly issued an RMA...return merchandise authorization for repair. They said this was a common issue with many TyTNs and I was surprised at their high level of customer service with these guys in contrast with the ignoring I got from HTC directly. Once they received my phone here in the US, they forwarded it to the US agent/wholesaler who then sent it to HTC Europe in the UK for repair. The turn around time for my situation was about 6 weeks, but it was during the holidays, so figure normally it would take about 4 weeks before you get the phone back under normal conditions. They repaired it very well and it works flawlessly....however, they do flash the repaired phone with the oldest firmware HTC has, so you'll need to do a firmware upgrade for your area/country when you get the phone back from repair, as I did. That's my 2 cents on this issue. So, yes, it is a repair issue.

i have this problem when i open my keyboard and in the same time i play some file in media player. then when i want to write sms, document or something my screen blacks out when i stop typyng

Got the same issue, not resolved yet. It happens most of the time while I am typing on MSN over wifi. As MSN is yet quite buged he may be the culpit; I may try to investigate a little more this issue.
EDIT: In fact my screen does not turn completely black; it just loses the backlight.

I have kind of the same problem. A while after I've installed official WM6 only the backlight turned on when I woke the device from standby. And sometimes the hardware buttons stops working, when this happends the lights in the green and red call buttons are on, even when I set the telephone in standby. Sometimes when this happends the orange charging light also turns on, and I get a bright blue flash in the bluetooth light(much brighter than the actual bluetooth light).
I've tried to turn of the standby, now the device never get black screen(it seems that the black screen only happends when I wake the device from standby). But still the buttons locks up randomly during the day...
Now I've downgraded to official WM5. The telephone was ok for a while, but now it shows symptomes of the same problem.
Is this a hardware or software problem?
Anyone else have this problem?

HD2 touch screen doesn't work

Hi guys,
This evening something wring happened with my HD2. Suddenly without any visible reasons touch screen stopped working. Actualy screen itself is working but it doesn't react on any touches. I did hard reset - no luck, screen is working but touch surface isn't, so basically my phone is almost dead :-(
Have you seen this behaviour ? Is there any possible way to fix it ? The only thing that comes in my mind which could cause something like this is static electricity shock, but if it kills HD2 screen I want my money back.
I guess now I should use warranty and this is just after 1 month of usage....

Just a stupd question
Don't be offended by my question, I just want to rule out the obvious.
You're not wearing gloves due to the cold outside?
Greetings
chuelibrueder

No, I'm not using gloves with HD2 :-(

I have the same problem. I believe that the connectors under the screen became loose.
I have send an email to htc and they told me to contact the retailer to check if they can replace the device and if not to contact the service center in Cyprus.
There is another thread about this issue here

i`m sure that warranty will solve it.. just contact your retailer.. good luck

Hmmm,
Yet another one having to go back due to hardware problems....
WB

I loose the touch screen today and the hardware button exept Home i think, i had to remove the battery and i waited 30s put it back and everything went in place, the phone had called one contact when i had the bug.
The only thing that happened before screen doesn't work and buttons : i received an MMS strange, i'm not sure i can rely on my phone
I only installed the 1.48 rom and the 3 patches (audio, sms and sd card)

I contacted the service center in Cyprus and they offered to repair it but they don't have spare parts right now. I've also send an email to the retailer and wait for their answer.
Seems i have to wait after Christmas for a repair or exchange.
The good thing is that by pressing the screen with my palm or giving it a few solid taps it works for some time.

bBeware keyboard layout!
I had suffer bye used hadwritting layout sometime it cause screen doesn't responds
try change keyboard layout not hadwritting

Just had the same thing happen with mine, powers up but the screen wont respond anywhere i press. I have tried hard reset AND soft reset, nothing!
Have just restored factory ROM, and deleted hspdl and dropped off at vodaphone in town. Im gutted!!

really seems to be a production problem: i had to send my hd2 back to htc for screen replacement just 4 weeks ago... same fault as yours: the touchscreen wasn't responding to input anymore!
the last weeks i noticed that many people had this problem too...

wow.. keeping a close eye on this.. guess the same problem from the HD is creeping up to the HD2..

Well im hoping vodaphone dont turn around and say its not covered under warranty etc, I had to [like most ppl] sign up for two years to get this phone, i aint gonna be to happy if i have to spend the next 21 months of my contract without the handset i wanted!

Yikes , yesterday my screen didn't respond either (for the first time). Soft reset didn't work. After taking the battery out and leave it out for > minute it still didn't respond. I pressed the screen a little and then it worked again. Not sure if it was because of pressing the screen, but it did look that way. I hope this will be the last time this happens!

tnx!

Well, it's been a few weeks now and I've had this problem several times again and worse, even after a hard reset; and almost each time I could fix it by pressing the screen/hardware buttons, but that shouldn't be the way, because I don't think it's good for the hardware, so I searched the forum and I think I found the two culprits (maybe a combination of the two):
1. The problem occured exactly the same day I began using my 16 GB card, class 2. It once happened that when I had the locked screen problem I took out the card and it immediately unlocked. But every now and then the phone still froze, even when I took out the SD card if the problem occured.
2. Then I have put off the automatic light adjustment settings and guess what; no more freezes!
It looks like a combination of power settings and use of SD card. I'm not very technical, but even when it looked like it was a hardware fault at first, it now seems it's a software fault after all.

Touchscreen doesnt work
Well F4CK my screen will not respond to touch at all anymore seems that this is a problem that is not well addressed tmobile is sending out a new one but the question is when will the touchscreen stop working on that "new" one.NOT happy at all.

Well this has now happened to me....no touch response but hardware buttons working, screen still displays-- off to JB HIFI as soon as I can to replace.

OOOKK I had this problem when i just flashed my phone with a costum rom. As far i remember my phone fall down once or twice but not something bad. I have the silicone cover and screen protector. If it was a hardware problem i believe that it shouldn't work at all even if you had to use the hardbuttons. Which that was how i would have to use to unlock the screen. I will go back to the factory rom and settings to see if there is any difference. My current rom is AthineOS 3.14 and Radio 2.15.50.14.
If for any reason you want to access your cellphone and you don't have time go through troubleshooting. I Suggest you download mymobiler which connects the phone and you can use it through your pc. Make sure you take the sd card before you connect. Here is the website www.mymobiler.com

In my case, my phone was RIP. The touch screen stopped working after installing a custom ROM. I installed the latest official ROM from T-Mobile and my phone and came back to life

my hd2 go in deep nap

It's a known issue. Sometimes a long press of the end-call button will bring up the display, but that's rare. It normally needs a soft-reset/battery out to reboot the phone.
It's obviously a software issue as the buttons light up when you press them, then turn off when they time-out, and then light up when pressed again, so the OS is still running happily in the background.

during my search and tries for applications and tweaks for the device, i remember i saw something that assign a display wake up on the long end press, and something that wake up on shaking the device, is there any confirmation if these tools solve this issue?

Nope - try them. You could be the hero that confirms it

Today was my turn to have that issue. Unfortunately :-(
I 've been looking for an answer, but there is no solution. Just a thread that talk about that the issue is caused by SD-card, corrupt files, formatting issue...
Please, do we have any solution for that issue? it started this morning and I have it 4 times today.

hmm. happened to me today. don't know what caused it.

I had this problem today as well for the first time. I thought it was to do with having the animated weather wallpaper and having rain. Today for the first time I had it predicting rain and my Leo kept saying "Loading touch sense" when coming out of lock. It's never done that before.
Then after an hour of lock it refused to wake, despite the physical keys lighting up.

I had this problem also today as well for the first time! But twice, so basically the first time and second time
First time phone wouldn't go on, touching the screen, hitting the spot where the lockslider was (in the dark), pressing short or pressing long on hard-buttons. The phone didn't respond at all.
Second time the hard-keys would light up, but phone refused to wake.

I had this problem.
Solution: Download an app called MemMaid and use the settings in post #75:
forum.xda-developers.com/showthread.php?t=596484&highlight=settings&page=8

For me it was the Disable Auto Device Lock.cab (in combination with windows exchange server) that caused the frequent HD2-doesn't-wake-up problem.
I uninstalled it and it is working fine again.
Have a look here, the exact same problem was discussed :
http://forum.xda-developers.com/showthread.php?p=5386344#post5386344

Aaargh. Just happened to me again. So that's twice today.Locked it with Opera open. Went to toilet. Came back and Leo wouldn't come back. Again the physical keys were lighting, but the screen stayed dark.
I'm running standard ROM that came with phone, 1.48.405.2 and then official hot fixes on top. Only using apps that came with the phone too.
Not done any tweaking besides cosmetic through the standard phone options.

guys let's try to focus here, we all have/had this issue. So let's try to remember what's the last things we dis so we can find the common cause so we can identify it.
Well I said in my post above, I read (don't remember where! ) that the problem is related to the microSD card.
Was logical for me, because I kept copying, deleting, copying tow large files large files in parallel, I mean I stressed my microSD. By the way it's the one provided by HD2 with the copilot in it.
What I've done, is that removed the microSD for a while and there were no freeing again for like 4 hours, and it was with screen off for like 1 hour and half, come back from the fitness, and it's ok.
Once back home, I backed up all my MicroSD to my computer, then formatted it with HD2. After that I copied back all my data to my micrSD. So far so good.
hint: what's the official SD Card Storage Cards hotfix from HTC for?

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.

Bricked Hd2?,I am a noob

So, my aunt gave me a hd2 she found yesterday and i currently have no idea on how to fix it and to make it usable. Currently the phone is able to charge with an orange light poping up. However, when i try turning it on, It vibarates once and only a black screen lights up. I tried googling the problem and so far, trying to hard reset or run bootloader only results in a black screen. Is the phone fubar or is there any hope of fixing it? thank you in advance.

plug it into a usb on PC with WMDC installed & run a rom updater & see if detects device.
Some links for HTC roms can be found in wiki & also the hard rest & bootloader key sequence ...
Make sure you know what what model you got before commencing with actual flashing though.
Too many Hd2 T-Mobile USA (TMOUS) die in the hands of the noob so read first ...

IMO it's more likely to be a faulty LCD or something related to(a faulty LCD motherboard connector)...

Could be, does it detect in WMDC, have you tried MyMobiler (link in my sig).
If turn it on do any buttons seem to function, doyou get any audio feedback when volume pressed up & down ?

could it be karma ?
where did your gran find phone ?
