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.

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?

Random screen blank problem

My HD suddenly developed a problem where the screen will sometime not turn on when come out of standby, or after soft-reset. When this happens, I noticed that the phone is still working because you can feel the feedback from the virtual buttons. The screen is just blank.
I tried hard-resetting it but during the process when the phone goes to reset, the screen goes blank again but the phone continues to function.
I think it is a hardware problem as when I soft-reset it, the "smart mobility..." screen does not even comes on. The phone just continues to boot up.
This only happens randomly and I cannot reproduce it everytime. I am concern that if I sent it for service, they might not be able to reproduce the problem and send it straight back.
I am from Sydney Australia so the only authorised repairer is Fonebiz.
Anyone has experience dealing with them?
Do they have tools to diagnose the problem even if they cannot reproduce the problem? I suspect the motherboard is faulty.
I really like my HD and this is just painful! Any comments or advise will be much appreciated.

I have the exact same problem which I mentioned: here though after some time I had the additional issue that the screen would come on but with an upside down mirror image, and sometimes when that happened it would also look very low res or pixelated or whatever.
I just mailed it off to a repair center in the Czech Republic. Hopefully they will be able to reproduce the problem. It was getting to the point where it would rarely turn on correctly.

Actually I also have the problems with upsidedown screen and the low res/faded effect.
Please keep us posted with the service.

So they are able to fix it? Gives me hope again

If the problem happens often and can be easily reproduced, it should be easy to fix. Problem with mine is that it only happens once or twice a day. I might have to wait a bit before sending it for service. Luckily I still have 10 months on my warranty.

untick "turn off device if not used for"
seems to have worked for me

Yeah sure that works but then the phone is always on so your battery gets drained real fast, not?

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.

Thanks... I'll just spend my time watching at it and hoping it will magically disappear like it happened for you!

HD2 Touch Screen Not Responding

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!

Can anybody out there help with this? I am currently without a phone :-(

I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help

Check the flex cable.. this part are very delicate.
is this :

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.

same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds

Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!

I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.

This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...

Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.

I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/

just got off the phone with tmo. they are sending me a new one.

Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..

I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it

After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...

I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?

Mine sometimes worked well for hours... days... but eventually the problem came back.

Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.

I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...

[Q]Thin blue line on screen

Today morning wokeup with a bright day,
I saw my phone working normal
I have mahdi rom on my phone..
But theres no issue with rom or any mod is what im sure about..

it does appear even on the twrp,bootloader and even on boot logo of circles too,

I don't think so, it is probably a hardware issue. Maybe you can check the inner parts of the phone or send it to a repair service. It seems like the connector between the motherboard and the screen is the reponsible.
