Just a FYI that the home,menu,back and search buttons stopped working yesterday morning. Phone was not damaged at all to cause the problem, the buttons just stopped working. Once it a while one of the buttons will work for 2-3 presses and then stop working.
Went to a nearby AT&T warranty center and got a replacement within an hour . No cost to me, we got the phone back in Jan/Feb.
Now to try out the ICS update!
This awfully reminds me about the Motorola Milestone (Droid for you US-citizen ), the touchscreen would go bonkerz when you exposed the phone to too much humidity, like using the phone when it rains etc. IIRC the problem was that because of the sliding mechanism, the back side of the display ways not protected anough and fluids could enter more easily than in normal phones.

I do not know if somebody faced this problems before or not:
1- The soft-keys, dial key, call drop key, and the scrolling keys; are always while pressing them for long time does not response until turning off the screen by pressing the power button then turning on again to keep working for awhile then same thing happen again.
2- The screen is sometimes fade to be completely white & brightness more, and everything hidden until turning off the screen by pressing the power button then turning on it again
If anybody knows how to fix this matter please provide me with the solution.
Thanks for all concerned
I had the same exact problem... I fixed it by getting a warranty exchange from AT&T!
I have the same problem! Unfortunately my phone is not covered by warranty. I think it's a hardware issue because I changed a number of ROMs and the problem persisted. I don't know what to do, it's driving me nuts!
Help anybody???
Good news!
Ok, as far as the key problem goes, using the PDF file about HTC TyTN where you can see how EXACTLY to disassemble and assemble the TyTN I took the courage to open up my TyTN and pull up the motherboard and clean everything up and close it tightly back. However I did not completely disassembled it as the manual shows because I did not want to remove any stuff that's glued like the rubber parts and the metal tape that holds the keyboard connector. So basically, I did not reach the part where the soft keys are, but somehow miraculously my keys are working nice again! I guess the problem was just loose connections and probably it was loosing contact somewhere because keys worked sometimes and then suddenly stopped.
Anyways, it's been 2 days now and the keys work perfectly and my TyTN is not so loose like it's going to fall apart as it was before!
P.S.
I haven't noticed the white screen problem also but it's been only 2 days and it wasn't happening so often before anyways.
This issue is known -there are threads in hermes section, search for white screen..
Its a harware issue with XILINX coolrunner(if I remember it right) on the front keypad below screen.. It propably has some bad solders under it -mine went so bad that it showed only white screen until I disassemled the unit and pressed directly the chip with my fingers
Then I bought a new circuit from cnn -at the moment it had those boards for sale, not anymore. That fixed my problem.
Among the threads someone got his/her phone to operate again by putting something between the cover and the chip..
I had the problem on my handset and managed to fix it by cutting up a piece of card..be it and old credit card or whatever to the size of the recess that the chip fits in...this pushes against it nicely and since then only had the problem reoccur once...then it was cured by just putting the handset into standby mode and back to normal again
I recently ( Monday, October 25) received a HTC Evo 4g. I rooted it on Tuesday, and installed the latest Cyanogenmod. It was not dropped or hit with anything, and has had a stealth guard on it since day one. My problem is, on Friday morning the touch screen and capacitive buttons would not respond to touch. The OS was not frozen, as the phone would respond to the volume and power buttons. I ended up having to pull the battery in order to reboot the phone. I did so, and the phone worked properly for an entire day. The next morning, after a night of charging, I picked it up again only to be met with a non responsive touchscreen. I restarted the device, but within the next thirty minutes the screen and buttons stopped responding again. I restarted it, and it worked for a few hours. The rest of the day it would randomly stop responding to touch an I would have to pull the battery. At first I thought charging was the trigger, but the screen has stopped working while in use and while sitting not charging on my desk. Hoping it was just a problem with the ROM, I switched to damage control and finally back to the stock (with root) rom. The problem persisted. As I said, I cannot find any kind of trigger, like pressure in a certain place, running a certain app, or doing something. Any suggestions, or should I return the phone under the 60 day warranty?
Also, I have tried searching for answers, but I have found only posts about the improperly grounded touchscreen, nothing like what I am experiencing here.
Factory defect? Unroot, put the stock rom back on at Shipped-Roms and bring it back to the Sprint store. You have a 30 time frame to return the phone and a 1 year factory warranty from HTC. Sprint WILL swap out the phone for free and give you a new one if under the 1 year warranty.
Seriously, this sounds like a factory defect and not a ROM issue.
A little while ago my battery ran out on my Xperia Play and nothing has really worked since then.
1. Backlight does not work, at all.
2. The phone does not detect the batter (though I am able to charge it). I have that 'no battery' indicator on the top of my screen at all times. I have bought a new battery, no change. If I keep it plugged in with/without battery nothing changes.
3. Screen is really laggy now. I have to try to swipe the screen like 18 times before it actually goes through and unlocks. When I try to type, the keys I press get held so all sorts of funny accents are all over the place.
Its not usable currently.
Note: If I use the arrow keys to navigate the menus, it works fine.
When I tried to take the phone apart I managed to break the LCD screen. Replaced that and now I'm back where I started.
Anything I can do? Replace the digitizer?
Looks like a hardware problem (seriously damaged motherboard?), and I'm 99% sure it's totally not screen or battery-related problem. If your phone is on warranty I suggest you giving it back, instantly.

Bah, I was worried it would be that. No warranty, I picked it up off kijiji for $200 last year.
My Desire Z had a fall, and has developed two problems
1 - The hardware keypad has started to take hard-press and sometimes prints double characters on single press. I think the alignment is out or something... any other guess ?
2 - The touch screen sometimes stops working from an inch up from the bottom and continues to half an inch. Before and after that patch, the touch always works fine . Mostly, the whole touch screen works fine. But when the patch gets non-responsive, I have observed that by turning the screen off and on a couple of times makes it work again. I am not very sure what the problem is. Any clues ?
Thanks
I'm also experiencing a similar issue - for me it's usually an area that corresponds to the top row of the
on-screen keypad (for unlocking) or the top of the area for unlock patterns (portrait orientation).
Mine is a 2 year old DZ w. Cyanogenmod 7.1
No HW key problems & no droppage.
Liberal application of isopropyl alcohol and a microfiber cloth - especially around the edges of the screen
seem to help a little bit but not often enough to be better than random.
Switching the screen off and on occasionally helps but most often I get annoyed and use the HW keys to
unlock.
I have noticed that, after powering on the device, the SIM-lock keypad works just fine but the (different)
screen-unlock keypad fails. This leads me to believe it to be a software issue.

Thread moved to Q & A section.
So i am going for Digitizer replacement will post the result when the phone is back.
And what about the Keypad taking hardpresses ? what can be the issue there ?
so my desire z is in the shop for repairs. lets see what problem is diagnosed.
I have read in another thread in this forum that the hardware keyboard (need to press hard on some buttons) issue can happen when the phone falls.
Apparently, the flat cable that connects the keyboard to the rest of the phone gets loose and causes such trouble.
Since your phone is in for repair, I'm sure this will get sorted when U get it back.
ok so my phone got back from repairs, the guy couldnt fix the touch-screen rather made it worse. Now the touchscreen doesnt work at all. So i cant unlock the phone and cannot test the Keyboard problem. The guy said the touch problem is related to the ribbon cable and not the touchscreen itself.
Note 1: He says he tried replacing the touch panel altogether but it didnt work.
Note 2: I still think the ribbon is fine (call it intuition)
Note 3: I am giving my phone for repairs again, but this time to HTC service center which would probably cost me a lot more than third-party repairs but at least it will get fixed.
I will update when I my phone back from HTC service center.
Could you not unlock the phone by opening the keyboard ?
It does smell to be an issue with flat (ribbon) cable to me as well. As if there was some loose contact before (caused by you dropping it), and after the repair guy took the phone apart, he probably made even bigger mess by ruining the flat cable completely.
From my experience (and I've claimed warranty 3x for the broken digitizer (touch panel)), if it's broken, an area of the screen (or the whole screen) will be permanently dead. It would not come back to life every now and then.
btw, mine always started being unresponsive in the very middle of the screen, a bar of height around 1 cm (somewhat less than 1/2 inch). Each time they replaced the digitizer.
If it;s the flat cable, you shouldn't end up being charged too much - those thingies are very cheap (in China) and the labour will probably be the majority of the price. Fingers crossed.
So I got my phone back again... The HTC repair center was not located in my city so I went to another (better known) repair shop. The guy said, "your phone hasnt been opened at all from the touchscreen side, any *repair guy* who claims he has opened it and tried this and that but couldnt fix is simply lying. This said, he opened up my desire z replaced its Touch Panel and voilah! my desire z is sensing again in 15 mins
What's the status for the keypad and need to press it hard to work ?
nope... I had it cleaned using alcohol / thinner. now it works fine.
So, I updated to CM 7.2 last night but the touchscreen problems are still there.
Updated using CWM and deleted data & cache whilst doing so.
I really hate the prospect of getting a new phone as the current models available
in DK are all without physical keyboards
Hello,
After I dropped my phone during workout very hard like several times capacitive buttons stopped working
actually I thought they got somehow broken but I realized that they are working when phone gotten moisten druing another workouts in my pocket they are working then It got dried and stopped working.
I wonder if digitizer got loose after dropped and when it gets moisten then it started working
I think I will open the phone and remove the connector of digitizer and put it back again.
intersting huh?

Well if you just want to fix it without much of a hassle, there's a work around to it, You can actually put On-Screen Buttons, and completely ignore the non-functional ones.
