[Q] Touch screen doesn't work most of the times - myTouch 4G Q&A, Help & Troubleshooting

Hi mates... First sorry for my english... I speak spanish.
My story here....
I was very happy with my Glacier MT4G since I used to come over XDA every time to learn how to root and stuff. Life was happy and colorful with all the things I was able to do with my phone..... until that day my phone just went bad...
it started with the headphone hole, I plugged my headphone and then nothing happened when ever it usually started to play music... Minutes later, as I was trying to realize what was the problem, the touchscreen just stoped working too...
A couple of months before it was having issues with the ear-speaker so I had to change it (not me, the repairman)... so instantly I thought the boy who fixed it could let something wrong inside but before I had to make some tests to discard possibilities
And then I flashed it first... it worked but after some time (an hour or less) it stoped again.... changed rom, and same....
So I thought it could be the digitizer, so took it to the technician and changed it.... same stuff... sometimes works, sometimes doesn't...
if i turn it on and works it takes some minutes to stop working and if I turn it on and doesn't work it just doesn't work
I know, boys... this could be some hardware issue... but if you know it isn't, it would be great if you let me know... or if you know which kind of hardware issue it is and you let me know that's even greater...
Thanks in advance

Grounding issue?

Trinity doesn't vibrate anymore

My phone doesn't vibrate anymore.
I've had it for 4 months now, and it never really experienced any real severe injurie but for yesterday I droped it in my car. Though I am not really sure it wasn't broken before. Anyway, now I can get it to vibrate sometimes, once to 4 times max, but then nothing.
Has any of you ever experienced such a breakdown ?
Yes i have,
there are 2 tiny screws above the vibrator. Last month one screw came loose and felt into the vibrator of my phone. mabey thats your problem. Do u heare someting inside when you shake with your phone?
Greets
nope, not really.
and I am too scared to open the phone. better wait 'til next week when I come back home and go straight to reseller to use the warranty.
thanks for the answer though, I feel less alone.
actually I am experiencing many problems at the same time...
I never could connect through GPRS or any 3G stuff, but I assume my provider is in fault. And I just installed WM6 by Faman, and can't even connect to GSM now ! I am going to reflash to normal WM5.
Hope they just change me the phone without arguing (and why not give me a P3600i instead ? yes I know, I'm day dreaming...)

Welcome tot he forum
Hoping that is not a hardware related problem I would do a reflash to try to solve it
Read in the Wiki on how to
Hope it helped,
That happens one day in the car travelling home that the sound suddly stop working i restart the xda and everything (not reflash) but nothing work i will try to reflash it because i think is not a hardware problem
is the first time i try to reflash my pda but i have a problem when i try to downgrade it that shows error 260 and i dont know how to fix it
ok, i fix the problem with upgrade xD my english is not good at all and i missunderstand some of the instructions, but after read 100k of threats and 5 hours trying things now is upgrading to tomal rom i hope that this will fix the problem i had before
after reflashing the ce two times the sound is still not working, i am updating now the radio from 1.09 to 1.15, the stereo speakers make a little bit of noise when a sound is played, the headphones dont work, the phone speaker works propertly, and the microphone works but only send the voice to the phone speaker ¿? i dont know why happens this last thing
radio updated and the problem continues anybody can help?
I think it´s a hardware related problem
Try to take it to a repair center
Good luck,
I have the same problem. When a sound is played it just clicks and that's all. I had a problem with my ribon cable and I took it out. I've done that before (it's my second cable failing), so I knew what I was doing. I was off for a about a month untill I got a now cable. When I put it back together, I had no sound, just that click thing. I can't take it to a repair center. If anyone has a solution, please share.
I also found that my camera does not work. It says Failed to initialize camera. 36001:100:1. I tried a different rom, but still have the problem.
Also I tried to make a phone call (I'm not using it as a main phone, that's why I just found that out) and I can hear the other person, but they can't hear me.

i also check my camera after reading your comment and i also have the same problem, next month (because this month i will travel and i cant do it) i will send it to repair a tell you what the solution could be
PD: orb3000 muchas gracias por ser tan atento
I have good news. Something happened. I dont know what i did... but i got my sound back (and camera. main camera at least).
As you I flashed the rom, then the radio rom and I still got the problem. So I thought I'll leave it like that untill I find a solution. And I thought.. well i can at least play some games on it and I downloaded Archibald. I put it on the phone. Started it and ?! I had sound. Again I dont know if I did something before that, but I got it working. I'll attach the game, maybe it did something. Give it a try.
Again I have no idea what I did. It might have some bad connections somewhere. I remember I had the same problem (either with the Universal or the Wizard) but dont remember how I fixed it.
Here is a link for the game:
i install it but the miracle didnt happens i also will try to remove the battery it have on the motherboard to make a cmos clear (like in a normal computer). Lucky you i will keep trying
I'm sorry to hear that. I didn't if it matters but my small mb battery is dead. Apperantly it died during the month the battery was out. Everything works except that when I do a soft reset, the clock resets too.
I have these problems too, does anyone know the specification of the mobo battery?
I have the sound problem but mine doesnt work even with headphones in and i also have a problem with the keys being activated when the screen is in a certain position. Could all of these problems be casued by the ribbon cable?Rob
As far as my expirience goes with the ribon cable, it commands the touch, the lcd, mic, speaker on the lcd part. the keyboard has it's own cable. and it snaps to the motherboard. maybe it's loose or something. For the battery I got http://cgi.ebay.com/Dopod-D900-900-T-mobile-MDA-IV-Qtek-9000-backup-Battery_W0QQitemZ350170469398QQcmdZViewItemQQptZGPS_Accessories_Cablesthis on ebay. But mine looks a little different.
also happens to me when i make a soft reset the clock also restart could be all because the mb battery is dead?
OK, we are getting somewhere Since my sound got back, whenever I reset I get to keep my current time. So maybe my mb battery fixed itself or charged.
I am pretty sure now that is what's causing the problems. If you could disassemble your pda, try playing with the battery. See if it is not loose or something. Try to short-circut it. Get a something form metal and touch both pins. Also try leaving your PDA charging over night.
I hope you fix it since I cant seem to find that kind of battery over the internet.

Hero LED's don't work any more

Hi everyone,
up to today, I was totally happy with my HTC Hero (unbranded).
However, the LED's (both on top and the trackball) do not show any sign of function any more.
The phone has not dropped and was not exposed to heat or anything.
First I thought this might be a software bug, but even after a hard reset, the LED's don't come up at all any more (even not if charging the phone).
Anyone else here with a problem like that? Any solution yet?
I almost can't imagine this is a hardware fault but on the other hand if the hard reset doesn't fix it, what could?
Thanks for your help,
Chris
Hi.
I can ask the very same question too... I have had the HTC Hero since the friday before yesterday and after a couple of days the LED's simply stopped working. I had thoughts about trying a factory reset but with your posting it seems it would be in vain... :-(
So yeah... count me up on this one...
UPDATE:
Today it is Sunday and the time here in Sweden is 22:05 and I had to do my very first hardcore hardware reset (HOME+BACK+POWER) since every radio in the phone simply stopped working. After the reset was done the led's still won't light up when charging...
The LED at the top doesn't light up for missed calls/texts/emails anymore (the trackball still glows)... although it does still flash for batt.low/charging it doesn't for anything else... I'm pretty sure it used to... or am I mistaken??
mine died 2 days ago, also did a hard reset and still nothing....today my headphone jack stopped working, just plays the music through speakers and ignores the headphones totally :/ not amused :/

i'm hoping it's a software thing, can't be that so many people have hardware issues at the same time :/

You just made me realize it's the same with mine
- LED's don't work (top and trackball)
- Button lights don't work
- headphone jack doesn't work any more either
So all these things seem to belong together...

What software have you got installed? Is this a similar thing like TasKiller that killed the clock so Alarms didn't work?
Then again, you said you did hard resets... But if you did a hard reset, it shouldn't be the software of the phone as thats back to normal.
Try taking the memory card out, only thing I can think of!

This happens when a bluetooth connection has been made. It ignores the headphone jack. Close the connection in bluetooth settings and it ill be fine.
Don't quote me on this, but I think I remember seeing an option in the phone setting section that controls the track ball and what not. It may be worth having a look.

Well... no :-/.
BT isn't switched on, 3,5mm headphones aren't even recognized after a hard reset any more.
This is not a software thing as it seems, at least not one the user can repair on his own.

Yeah, you're right, there is an option for that. I've switched that back off and on a thousand times before and after hard resetting the device, that doesn't help unfortunately.

Yeah... I only got standard soft like shazam and streamfurious installed. Then after the hard reset, only stock software was on it of course...
Seems like it's a hardware defect or something the user cannot influence software-wise. May hard-resetting doesn't reset everything in the phone, who knows. I even took out SIM and SD card, no luck.
However this is a bug HTC should look at closely, people are complaining in several forums and it seems like I'm not the only one with this issue...
i don't use BT, never turned it on and just checked, it's obviously off :/ don't remember coming across a trackball option in settings, but Notification option is on :/
let's just assume that it's not our doing since so many people have same 2 problems
Mine packed up last night must be a tech issue I think heat
sorry for asking a silly question though. is the led supposed to flash on missed calls or messages? cause the only time mine works is when charging.
I have the same problem. after a few days the headphone simply wasn't recognized. And at the same time the LED's and trackball lights were broken.
Hard reset didn't work.
It was after I rooted the phone.
How was that with you?
For the headphone problem I found a workaround. This switch-widget turns the headphone back on and the speaker off.

same here, check topic Q&A but here also the alarm doesnt work correctly...djeezes;..
same here!
well i have the same problem whit the LED's.... just stop working aften 3-4 days of use
maybe we should all write to HTC to complain as a group, this definitley looks like a manufacturing fault to me , esp as it is happening so soon after buying and using

Sprint Hero screen issues had CM6 installed

Hello all and thanks in advance for the help.
I just got a refurb Hero from Sprint a couple weeks ago. I Rooted with Z4Root and started trying out Roms. I had just went from CM 6.2 to 6.1. Had everything working fine until my screen would stop coming out of hibernate mode. I would have to reset the phone to get the screen back on. It has gradually gotten worse (over the course of one day). Now when I reset the phone I might get the screen to turn on 1 out of 40 times, but the screen is now all messed up even when it does turn on now. I cant figure anything out other than to answer a call because I know where the slider is supposed to be on the screen for answering calls, so if someone calls I cant see anything I just swipe the screen and it answers fine.
Any ideas what might be causing this issue? Would it be a harware issue?
Thanks again
Yea I would try a different download you might have gotton a bad one. Also you should try a different rom after a full wipe. If that didn't work then I would say its a hardware issue.
Something.About.Me.U.Don’t
Like.Its.Cool.I.Understand.
.AWAH.
Thanks for the reply. I did nandroid back to every previous backup I had. Now I cant get the screen to turn on at all so, Im guessing its hardware. taking it to Sprint Today, we'll see what they say.
Thanks again
Yup, They replaced the screen and I'm back in business!
Swwet, glad to hear it man now enjoy more xda
Something.About.Me.U.Dont.Like
Its.Cool.I.Understand.
.AWAH.
I was just wondering if there was something to do with installing different roms that could have cause the screen to go out? I am thinking not, but I am new to the whole rooting and rom-ing thing. Is it possible that something I did caused the screen to go out?
Na I doubt it. Hardware usually is the manufacturers fault or user error. Unless you droped it, banged it up real bad or flashed a gsm radio your good. And a screen issue such as yours is most def not a rom issue.The rom dev's on here are solid. And XDA is a well known and respected site. If you need any help with anything just let me know.

Weird HD2 unresponsive screen

Now I've read about a problem of the hd2 having digitizer problems and that only a replacement will fix the unresponsive touchscreen issue. But why is it that when I can get my touchscreen to work that it works flawlessly until it goes to sleep? Then i have to continually wake and swype and sleep over and over until it responds. It just seems very weird that after it wakes that it never seems to have a problem. I'm using the miui rom right now and have set the screen to never go to sleep. So I want to see how long it will go without this problem. Has anyone else seen this happening with their phone as well?
Make sure the kernel, and Rom are up to date.
I have that too on an AOSP Gingerbread rom. The screen is not unresposive per se but calibration seems off some times, strage for a capacitive screen.
ive had the problem with android before and there were a few different fixes ...
one fix was to turn off compatibility mode
another was kernel
ive also had the problem with wp7 ( nothing a few hard resets and patience couldnt cure )
either way good luck
well since my first post, i hadn't let the phone go to sleep once and it worked perfectly fine. so i decided to turn off compatibility mode and let it go to sleep.... and when i woke it and i slid my fingers down it actually worked. so far it's worked every time. why would compatibility mode mess up the touchscreen though?
i have NO earthly idea! just a little tidbit i picked from a dev. i would speculate but would end up looking and sounding foolish. so im going to quit while im ahead and have actually been of help :-D cheers
Where can i disable compatibility mode?
I get the same problem. I've used a ICS rom for a day or so and suddenly the lockscreen was unresponsive. I thought it was ROM problem, so I flashed Cyanogen 7, but the screen didn't respond as well... I flashed everything to stock (removing magldr and hspl) and the problem stayed... After several restarts the screen started to respond and now it works (sort of). The tricky thing is: sometimes when I go out from some app in android, the screen doesn't respond again. Locking and unlocking the screen fixes this, but only temporarily.
Did this ICS rom screw something (...hardware?!) or is it a pure coincidence that a few people encounters the same problem for the first time in such a short period of time...
And one more thing... my warranty expired 5 days ago... please help!!!
I had this same problem with my phone before my warranty expired; before I flashed any android roms on it, and while it still had stock WM6.5. I called HTC customer support and they had me send in the phone for repair. They replaced the digitizer and I haven't had the same problem since. It was wierd because in my mind is seemed like a software problem because it would respond nicely as long as the screen was unlocked and the instant it was locked the response was very crappy, sometimes it took forever to unlock my phone. So it might somehow be a hardware issue

spare parts!
I repair phone myself and i can say that i get A LOT of hd2's with this problem. For the most part it is the hardware because no matter what software you put on the phone it is just a matter of the luck you have to get it working. My hd2 broke 2 times b4 and it was always hardware. Htc must of messed up with the hd2 digitizer

from what ive seen in photos of the leo mobo it looks like the connection for the screen/digitizer (not sure on hardware) is located right behind red end call/power button and from being mashed off,on,off,on,etc loosens/damages connection.
or is the hardware screen issue just a complete shot in the darks chance?
OH ... ive had the software issue (fixed as i mentioned earlier) AND unrepairable (with my limited tools and balls to physically tear into this badboy) hardware issues.
well, it's been a few days and my phone still seems to be fine. it hasn't once locked up on me yet. i don't know why turning compatibility mode would fix this. or maybe the phones connectors were loose and are now miraculously back in at the same time i unchecked compaibility mode. the only bad thing was that this was happening the last couple weeks and i had given up and already ordered a sensation 4g. or well, guess i have 2 phones now
Its seems possible. Every since I replaced my digitizer with a non OEM one its has never failed on me again. And I hope it never does. There dam expensive.

Compatibility Mode
I also have this issue, therefore I just recently flashed my hd2 with Tytung's 4.0 ICS Rom. As expected, this didn't help very much.. What I am now going to try before I send my phone to HTC is to disable compatiblity mode. BUT, I can't seem to find this compatibility mode check anywhere. Could someone please guide me there?
..
Windows 7
I will be flashing my phone with w7 now, to see wether this is an android kernel bug / softare issue or if this relates to hardware. I also see a lot of people saying that after fixing the digitizer it works again, so it might actually be a hardware issue. I will post my feedback when I have tried with w7.
