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

Just wonderng what other peoples experiences are with blue angels, I have an mda 3 model and I have had nothing but problem after problem. I have the buzzing screen which has grown to intollerable level, My internal battery keeps draining for no apparent reason, my power button snapped of the mainboard a couple of weeks after purchase and T-mobile would not fix it,
After having it fixed a few months later my power button now only works when I hold it to turn off the backlight but I cannot turn off the screen by pressing once (A few others have had this problem) it's not a hardware issue I don't think because I had it back to a phone shop that specialises is PDA's and they say noting is mechanically wrong with it. From pressing the power button once it seems to stay in the memory or whatever that I presses it and then when I do a soft reset, It hard resets. My internal battery has now started behaving but I still have this power button prob and the buzzing screen.
Also did they put legs in these styli because I have had each xda model and never lost as man styli as I have with this model!!!!!!
Just wondering if anyone else shares my frustration, I have had tons more probs and will post when I think of them!!
**** presses = pressed
Yep I have tried flasing it with different roms and still no change. Im now back to my trusty old xda 2!! never had a problem with that[/code]
Probably, if is not mechanical, the problem is in WIN OS - upgrade new room,other room,oher room etc.

Lol!
Same here! :lol:
But beside that, I don't have any problems with my MDA 3 (knocking on wood :wink...
I was having that prob. then i looked at the side and realised one of the screws holding the ba together had fallen out
Id started thinking it was a software fault, but its definitly not as I have installed countless roms and just put WM5 on. I took it in for repair this morning (as last time they put a dodgy screw back in and I cant find a screwdriver that fits!!) and they are having a look tomorrow! I will tell them about the screw so cheers!!
Which screw is it then? inside the phone?
no its the one at the top, on the side next to where the stylus is held.
you may find its loose and when you tighten it the stylus stops falling out as much.
speaking of those T-6 torx screws... where can they be bought, or found?
So my phones earpiece began to cut in and out, which I found to be a chafed and broken flex cable. No biggie, I ordered a replacement piece and waited for it to show. As I waited the phone began to get worse, I lost the earpiece entirely, the leds stopped working as well as the sleep button. The screen, now only able to be woken by sliding, would not come on when slid out, but only once it returned..also the screen would shut off when I would slide it out again.
I have seen disassembled the phone again and installed the new cable and all is well, with one exception. The slide function of the screen no longer works, period. It will not wake, it will not rotate, and the keyboard doesnt illuminate unless I press a key. I have been through this phone 4 more times now and I simply cannot pin down exactly what tells the phone that it has been slid. I have heard talk of magnets, but found no sensor or magnet, I saw small contacts..that are all functioning properly. There is no cable or connection to the screen portion that connects to any sort of switch that I can see.
Does anyone know what triggers the slide?!
Sorry mate, im not an expert but I thought this may help.

The link is to the FCC website showing links to internal photos of the phone, SAR values, micellaneous stuff, etc.
Maybe a different perspective of the phone might help.
Hope this helps you
Don't know if anyone else is experiencing this with their Play but as of a week or two ago the backlight started acting strange. The backlight will randomly stay off when I push the power button with the slider gamepad closed. Only way to make it come on is to pop out the slider. It seems to be random, and if I push on the slider edge slightly with my thumb with the slider closed the backlight randomly flickers, ranging from slight to severe.
The display is still working despite the backlight issues, I can open apps, and use the phone normally but the backlight flickers on and off. Makes it especially hard to use the phone in the dark.
Phone has never been dropped once.
I've replicated this problem with a variety of roms, both custom and stock. It's definitely not app related or even custom kernel related. It happens on a fresh wipe with stock rom with stock kernel. It happens on CM7 with custom kernel.
I'm curious if anybody else is experiencing this. It would tell me if it's just an isolated incident or if others are having this problem.
Sounds like a faulty connection to the backlight to me.
I had the same problem 2 days ago. Then I couldn't get my phone screen on at all!
I sent my phone back to Sony, even thought I bought it second hand. Phoned them up and talked to them. They asked what time of year I bought it so I said around August and then they gave me the address to send it to. Now I'm just waiting to see what happens next.
If your going to send your phone to Sony for repair then make sure you put the fresh firmware back on and un-root your phone as that breaks the warranty (unless they don't know about it)
Hope I helped you. If I did then click the thanks button
Sounds like a faulty ribbon cable to me. (cable that connects the screen to the rest of the phone)
You wouldn't need to drop it for that to go bad, It could just be a case of opening and closing the gamepad or lot.
Yeah good thoughts, most likely the ribbon. That really sucks because I've only had the phone for 7 months, and I've taken excellent care of it. Sounds like a major design oversight.
Mine is probably near complete failure at this point. It's taking a lot more effort to keep the screen on now. Fearing soon it won't work at all.
In hopes that this might help someone else down the line, I was able to fix my problem. Yesterday the screen pretty much quit and I had no choice but to try and solve it myself or buy a new phone.
Using this disassembly video as a visual aid I carefully pulled my phone apart: http://www.youtube.com/watch?v=-3n5ZfkqhzE
You'll need a torx T5 tool to pull out all the screws but they are cheap.
Underneath the phone and jammed into the screen ribbon was a rather thick hair just hanging out. Somehow it buried itself in there. I removed it, unplugged and replugged the screen ribbon and cleaned the dusty inside with a q-tip and reassembled it all together.
It works fine now, so hopefully this helps someone else avoid having to pony up for a new phone. For those under warranty probably best to send back but for those like me with no warranty it's worth the shot.
hi im having a problem with my desire z keyboard. some keys such as O, P and S are not working well. like i have to press them really hard to bring the letter on the screen. the hardware touch is fine like the keys feel normal when i press them but with some 4 5 keys, the letter doesnt come up unless i press really hard. anyone else having such a problem and solutionss?
I am having the same problem, but I've kinda got used to the on-screen keyboard anyways.
Same problem here, and for another 3 people on Polish forum said about this too. I have send my DZ on warranty - waiting for answer. I have rooted ulocked and changed rom so I am curious about what they will say :> Depending on how much people have this problem it's a hidden defect for DZ not caused by user.
I have problems with my "a,s,d, and spacebar". Too bad that my Desire Z's warranty is already expired. Agree with the other poster, best way around it is to get use to the touch screen keyboard.
Sent from my HTC Vision using xda app-developers app
My DZ keyboard had been working perfect until recently.
The 'i' key and space key need to be pressed hard to register. But for the i key, sometimes if I press it hard enough, it will register twice. I think it is related to dirt/dust getting into the key or aging issue. And since my DZ is nearly two years old, I am not complaining. Anyone tried to take their phone apart and clean or replace the keyboard?
As i said before, I have send my phone to HTC Service with this problem and yesterday I got it back.
My phone was rooted and "htcdev unlocked" with Virtuous Sense ROM on board when I sended it and... there was no problem with it . They replaced "FPC Pre-Assy Qwerty" and didn't even restore orginal OS. Keyboard is working perfect.
Im having problems with my . button, no more warranty, so i guess i just have to live with it...
Have you attempted to shift to a different ROM? I had encountered certain hindrances akin to this whilst utilizing certain beta ROMs. Upgrading the ROM had solved this. Alternatively, it may be a hardware malfunction.
have the same problem as yashif,o,p,i,u need to press harder sometimes it register the key twice is it a hardware problem?

Sounds like dirty contacts in the keys. the proper way to fix this is to carefully disassemble and clean the keyboard parts with some diluted isopropyl alcohol.
The _improper_, _unsafe_ _lazy_ method that does not require disassembly but is probably a stupid thing to so (but I've done with success on another phone, not a Desire Z), is to remove the battery, spray a bunch of DILUTED rubbing alcohol onto the keyboard, saturating it so that it runs into the nooks and crannies, then repeatedly press the buttons up and down -- with the idea that some alcohol gets into the contacts and cleans them. Let the phone dry completely for 24 hours, put the battery back in and hope it turns on, then hope the keyboard works again.
Let me stress that I would only do this with a phone that is past warranty and that you wouldn't mine if it never works again...
Hey guys.
Late response but I happened across this thread when I was having this problem for a few days. I slowly realized after reinstalling my ROM with no joy, that I'd actually experienced this problem before, back when I'd taken the phone apart to replace the screen. Back then it turned out i'd left the keyboard ribbon cable loose which was causing some of the keys not to work.
Well it appears this time I may have knocked the cable out of place after dropping the phone (I do that alot) as after opening the phone, taking the cable out and then simply popping it back in, my ketyboard was back in working order!
If anyone is unsure about opening up the phone and trying, it's simply the first 3 minutes of the below video, upto removing the ribbon cable (just take it out and pop it back in, easy!)

Good luck!
DONT spray a bunch of DILUTED rubbing alcohol onto the keyboard
sorry for digging old threads but i had this problem and i thought someone will have it in the future
PLEASE DONT DO THIS:

The phone is too well made it has 3 layers until u get to the contacts
and is 95% probable you hard brick your phone
Dust CANT get to the contacts, instead the problem comes from the metal part touching the contacts that is bent overtime.
these things look like a ( and when they are pressed they go like this | and in the middle of them you will see
i will make a full tutorial how to repair bad contacts on this
Aaand.. here it is
So I got my "faulty" HTC One X 32gb, which I managed to get for $100 working yesterday with help from a person here.
Anyway, I've noticed a strange issue, the keypresses of the power button will be simulated occasionally with no actual pressure on the power button, sometimes this is left on long enough to both shut off and turn on the device.
I opened the device and there appears to be nothing physically wrong with it, this problem occurs regardless of ROM or hboot.
This is a truly strange issue and after placing the buttons back in correctly, it doesn't appear to be registering the power button at all, even if it has a satisfying click like on my other one X, I think the issue lies within the internal button, but how do I fix it?
Edit: After leaving it overnight in the same position (no movement) to copy files over, it did not continue with the issue, which leaves me to believe the angle of the phone/gravity has some effect, although there are no loose parts to highlight what the cause is.
Edit2: It appears this One X has been repaired before, I have a suspicion it's a new case, unless the white One X is supposed to have a different feel (smoother) to the black One X.
The screen may have also been repaired, as the copper tape that would normally cover the battery is gone, and the battery is loose, so the adhesive was loosened.
I got the same problem! At first this problem was just for 5-10 minutes. After that, it would act normal again. Can't remember when, but after some days or weeks it stopped and i thought it was fixed, Now, some months later the problem is back. But this time it locks like 2 times a second. So my phone is unuseable. I can't even backup my files because it reboots or power off. I also opened my HOX but cant find anything inside, looks good and no damage anywhere...
I will leave my phone for a day. Hopefully it will work after 24 hours...
