[xdaer]

Hi All,

I have a TYTN S/N 640

Screen goes black randomly although power / backlight / button lights are still on.
I have tried with/without radio, no software installed soft/ hard resets
It even did it after booting from a hard reset.
sw i installed 1.35 tytn rom same thing
Any ideas?
Searched forums couldnt find anyone with the same issue, apologies if I overlooked something.

Thanks

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

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.

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?
