Screen going black

I've tried various different ROM images (including the excellent Dr.Gonzo), and I have this problem with all of them.
When I'm using the phone either with the keyboard in or out, the screen just switches off randomly. If I wait a few seconds (possibly the backlight timer length), then it comes back. Mostly... Othertimes I have to wait a lot longer, but it does always come back.
A reboot sometimes fixes it, but not always - does anything survive a reboot or battery removal?
Anybody else seen anything like this? I have seen a lot of threads about the screen staying on, but not off.
Of course, it could be a hardware fault, but because it's intermittent, it's hard to prove.

same problem

If you shake the phone can you re-produce this problem? I've never not heard of this being affected by software - you might also want to ensure you're not overclocking it.
Nothing is removed when you do a battery removal or reboot, ensure your connections are all tight and make sure the SIM pins are all making contact and the SIM door closes, apart from that it sounds like a possible bad LCD ribbon.

Shaking it doesn't reproduce the problem.
Once the phone has started doing this, it happens everytime you press a key.
Seems more like a memory leak to me since it always seems to happen after a while of web browsing/email use.

So actually, it looks like it might be a hardware fault.
I think it happens when the device gets warm. After a few minutes with the screen on, keyboard lit up, wifi on, the phone gets pretty warm and that's when the screen seems to go black. Leave to cool and all returns to normal.

Same issue here, but the screen does not acually go black/blank it just seems that the screen backlight does not turn back on from a standby like state, the phone itself functions but just not able to see whats going on on the screen.
(keyboard lights work fine and come on when expected)
Not sure about the heat theory as it happens (to me) most often right after a call, anything over 30-50 seconds and the backlight problem occurs, when it decides to work again is a matter of luck.
As said before because it's intermittent, it's very hard to prove.
Has anyone who has had this issue, fixed it with a hard reset ?
Very strange ... but also getting very annoying now!

i got the same thing. took it back to warranty and they said nothing's wrong with the phone but i still get this.

I experience the same problems.. it happens pretty random, but every time when you hit a key. I have set all timers to never but the problem is still there.
Running Gonzo 1.1 at the moment, upgraded from guava.. but that didn't solve the problem.
It is getting so annoying now that I am about to throw the s710 in the dustbin

I have had the same problem!
I have turn it back to my provider and no problem now.

i have the same problem with my VOX
apparently, i can still receive phone calls, and do whatever i want with the phone,
but the screen just stays black, its like if you have unplugged your monitor
since i dont have a htc center in my town or anywhere else nearby.
does anyone know a way on how to open the phone, change what need to be changed and correct the problem? im all up for testing if that would resolve this annoying problem :s
cheers everyone

there is a dismantling manual somewhere in this forum. search.
i don't think taking it apart would help you because this is not a physical fault that you can locate.
and i learned that mcel is the retail seller of vox in mozambique. they should be able to help you with service. else just send a mail to htc support and they will guide you.

yes, mcel are the retail sellers, but i tried to go there, and there are no specialists on htc's there,
the thing is, i didnt bought my htc from them, so i can't go there and change for another one
but tks anyway

no problem
but do try to contact htc support by email. they might suggest a way.

I'm having exactly the same weird problem and I think I found some pattern when it occurs. Well, the thing is that in the bright day or in a room with lots of light it works just fine. In the darker conditions… well… not so fine. It seems to me that this screen blackout happens whenever the keyboard light is on and screen changes to full brightness (in the dark, because of the light sensor). In the daylight, keyboard light doesn't turn itself on, so s710 works. I don't know much but this definitely isn't some bad contact problem. Maybe some battery problem, but I doubt it since I can receive phone call in this condition. This started to happen after I flashed this Windows Mobile 6.1 ROM from HTC (I have original S710). Flashing Dr.Gonzo's later on didn't bring any luck either. I believe that some power control SW is the main culprit. I've read that many people mention some Tornado Power Control app. Does anybody know can this application be permanently disabled or removed?

are you trying to say that by desabling the light sensor, the problem might go away?
i would also like to know if it possible to have the baklight on the lowest possible brightness forever, because it seems, on a low brightness the problem might go away

I also have this problem with the lightsensor turned off. And also at (as it seems) random moments.

well, even with the light sensor turned off, the problem persisted.
i got my phone to a repair shop of htc's, and they figured out the problem
my phone is now 100% thankfully, the repair man told that the problem was because of bad or malfunctioned circuits, he exchanged them with new ones, and the problem went away,
dont know wich circuits exactly, and he didnt want to tell me, but i suggest anyone having the same problem to try and do the same
probably its a hardware malfunction with these VOX,
its possible since so many times before i've heard about malfunctioned pieces coming out in large quantities for sale.
anyways, cheers everyone, and good luck Portugal in EURO!

I have the same problem. I just noticed that it usually happens when the phone is warm, so if you need to do something on my phone just... take some ice from fridge and put it on back of your mobile. I cant see any more solutions.
Please someone help us!

Update. Problem Solved
Just thought I'd update this thread I started.
I sent the phone back to my dealer (Grapevine in Poole,UK).
A week later, I got a brand new one back from the HTC repair centre.
So far, so good. Looks like the problem's solved.
Mike

Sam problem here,
i called with HTC and they sent them to there repair centre.

Diamond Screen Problem

I need to align the screen again & again can any one help me out wer the problem lies

how did this happen? i also encounter a similar problem, when the phone gets warm... when i press on the right side, the click registers mode and more to the left... and when that happend, if i try to go to the alignment screen, it just hangs in there like.. forever... if i put the phone in standby mode, everything gets back to normal in a few minutes.. the problem repeats every time the phone gets warm...

Same
First i was also having the similar problem but now its totally unaligned i.e even after a time its same i click on extreme left it click on extreme right

nasty man... dunno why this is happening... so, my screen is dying.. damn :| what kind of mods did u do to your phone? software ones

I have the same problem! Seems this is an manufacturing issue that's affecting many Diamonds! Does the warranty cover this?

YEAH! ) i sent mine to warranty today, lol 15 long days at max until it will be back in my loving arms

i dont know if this might help
i used to have flickering screen, not being able to display alpha blend, transparencies or the colour black, and also not being able to keep the screen alignment (it resets everytime i soft reset the phone) ....
this happens when i used the latest update from htc.
it seems that the upgrade is not suitable for devices bought in 2008 as it has the ols original spl.
i read in the forum and found out that the radio, and the hard spl was part of the problem. so i read on and found that by using Olipro's hard spl 1.93 will fix most of the problem. but its for only gsm devices.
i flashed 1.93 hard spl and all my problems went away...
just sharing!!

i can see some leaked fluid above my screen ........... i cannot even explain it , because it's above the screen but i cannot touch it ........ so it's in between.....

i've had the same thing happen to me and sent it in for warranty.
came back ok for awhile, now its happening again. I usually just suspend my phone (power button) and give the LCD a rub that helps it a little, buts its quite unbearable at times.
I've sent it in to warranty for a second time today, warranty is expiring on the 8th of next month so they better fix it by then .

Guess im lucky

I have the same screen align problem. When the phone gets hot, the screen alignment screw up, similar to this one:
http://www.youtube.com/watch?v=5-IUzerAT0s&feature=related
I was told this is a hw problem as I've tried flashing different ROMs, update radios etc. but still doesn't help.
Right now I'm trying to avoid using the phone when charging or when it becomes warm. That seems to help a bit. Not sure if replacing the screen will help but a few folks here have suggested that.

ye iv had enough of this problem shall embark on replacing the lcd in a few weeks

dont think that actually helps - you'll prob need to replace the digitizer .

Long story short: it is a hardware problem! nothing you can do to fix it via software... and it gets worse, so get it fixed
I have just received mine from service a few days ago... Of course i lost my warranty and I paid almost 200$ to get it fixed... The front case gets replaced entirely (that includes both digitizer and LCD), because it comes in one piece... all components are stuck together that is, even if you have a perfectly working LCD, it will be replaced anyway... Fortunately this helped and I am not experiencing any problems... Also I've been told that this problem may occur again, after some time (1-2 years), if the phone is heavily used (gps, connected on 3G + screen awake for a long period of time), and that the simptoms may vary: some get the digitizer / misalignment problem, others get weird spots on their lcd, etc...
Hope i didn't make to many mistakes and that my reply will help you understand and get your problem solved...

I'm not too sure about that actually - how you stated the LCD / Digitizer and case comes all in one.
I've actually experienced the same issue, sent it back the first time. Fonebiz did not replace anything but a flex cable. Ironically, issue came back after a months time.
Sent it in a second time for warranty, i specifically included a note stating the issue - they replaced the LCD, but did not replace the digitizer; so guess what ? issue came back within the month.
Phone was finally out of warranty, i decided to send HTC a ***** email and they were very helpful and they've promised me a replacement. Waiting for Fonebiz to check for hardware faults if its all clear then i get a new phone

i assure you cannot replace just the lcd, not without a hammer! I got my old part back, I can take some pictures of it, just in case And the digitizer is one and the same with the front case... the diamond is a very small phone, that's why there are no screws or other stuff to hold together the lcd and the rest of the case.
So unfortunately for you, they may have told you they replaced the lcd, but i think they did nothing :|
It is very clear that we had the same problem... the digitizer itself got broken... not some cable or lcd
anyway, if your phone has warranty, you are a happy man

[Q] HTC Touch Pro Touch screen problem - fixible or not?

Hello,
Yesterday I was on a trip and I think the fireplace might have damaged my phone. The touch screen doesn't respond at all, I tried hard reseting it, and I will try to re-write the ROM, but I think it's a HW Problem.
Anyways, the warranty is out, is this problem fixible somehow, and how much could it cost? Thanks a bunch. The main problem is that I can't send SMS, I write and anything, but the send button is on the screen itself.

[Q] HTC HD2 Screen Not Working

I don't know if this was ever fixed but I just bought the HD2 off a friend and i saw it work for him but when i received it, it boots up normally, but then when i try to touch the screen, nothing responds except for the actual buttons. It seems to be running fine, just the screen doesnt respond to anything. No warranty. Is there a fix?

It sounds like the digitizer may be busted... You could consider trying to replace it yourself but it's a tricky business, especially when some models of the Leo require soldering to get the new one on
You could also try a different ROM. To be honest though, I would ask for your money back, as it's not in the condition you wanted.

I am wondering if this truly is a digitizer issue. This happened to me the other day. I reflashed my nand rom, and it eventually "woke up" and started working fine after about an hour.
Very strange, indeed. I'm hoping it is a software issue and that my digitizer is not failing...
love to hear some more thoughts on this!

I also have this issue, but when I press the screen very hard (very very hard) or when I press the end call button continuously then it works all again.

Same thing here. I got my HD2 since last March. It works really well until recently. If I let it sleep, the screen would not respond at all when if I wake it up. Luckily, it still under warrantee so T-mobile will replace a new one for me.

Problem with the proximity sensor, please help

Hi all, I have a weird problem with the proximity sensor in my HTC Titan. I got a new Titan about a week ago, to which I immediately installed HSPL and Dynamics rom. After I did all the tweaks and installs I like, I noticed that every time I dial a phone call the screen goes off and stays that way until the number I called answers. If the number does not pick up, only thing I can do is remove the battery basically to hang the call up. I noticed that removing the back cover slightly affects the issue and its easier to get the screen back on (by pressing the power button), but still removing it does not solve the problem. With a handsfree I can actually stop the call as it has an accessible end call button.
I tried flashing another custom rom and also a stock rom, both had the same issue. So, I took the device for warranty repair. I got it back today from HTC, with a note saying that software has been updated and problem has been fixed. I tried the device and surely it was working. Well I can’t live without an fully unlocked device and against my better judgment flashed a custom rom again… And surprise surprice the problem appeared back.
Im thinking here that could I adjust the proximity sensor from the registry, if its somehow too sensitive or something. Strange part naturally is that other people with same rom are not experiencing this behavior, so it is device specific problem. Also I don’t think I can take the device back again and say yeah I was flashing some custom roms on it and lost whatever you did with it.
There a Proximity folder at HKLM and I tried changing some values there but no affect at all. It probably would be better to have someone who understands about the values little try to take a look.
Thanks a lot!

It's a hardware problem. I got the same issue after 2 months of use. I sent to repair but they wanted to charge me to do that, so I haven't fixed it but I still can get the screen back by pressing and rubbing my finger on top of the sensor.

But when I got it back from repair today it was working. I made few phone calls and it was working totally like normal.

you are not alone

I can tell you that you are not the only one with this problem, it happened the same to me. I'm still unsure if the problem is hardware or software, but I think it's software because it happened just after I install Dynamics_2.0_Titan. I really wish that someone will bring a good solution for it.
