noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks

i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board

Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

There is no touch screen input. The phone works fine but no touch input.
I did a hard reset. Nothing. Any ideas ?
Im thinking there might be something wrong with the screen itself. Maybe if I take the phone apart and put it back together I can see whats wrong with it.
Same thing happened to my Tilt 2 (stock ROM). I tried a soft reset, hard reset, and then reflashing the stock ROM again. Nothing worked, so AT&T warranty exchanged it.
I believe is a hardware problem... Maybe your Rhodium got wet or something like that... You shoul go to your carrier and ask them if the warranty cover that...
actually i had the same problem---BUT
I did fix the problem myself...when it first lost its touchscreen capability, i accidentally pushed up on the bottom of the touchscreen (bottom of the phone) for a brief moment and touched the screen while pushing on the bottom ---AND IT WORKED...but as soon as i stopped pushing up on the bottom of the phone...the touchscreen stopped working......so I simply took apart my phone till I reached the lcd/touchscreen---I even disconnected all the ribbon cables ... (I could not figure out what the problem was because I had originally thought a ribbon cable that goes to the touchscreen had been loose-but all the ribbon cables seemed intact while I took the phone apart)----so I decided just to put the phone back together - carefully AND as soon as I put the phone back together, I turned it on IT WORKED! No problems since...
I really did not want to send the phone back to att because the phone that they sent me was actually 1 phone out of 2...yes thats right I received 2 phones whenever I ordered my phone...they have been doing this for years now...so I dont feel bad
good luck if you decide to open ur phone apart - it was rough...and time consuming ... but if you have a little patience - u should be good
Thats good you were able to fix it..... the same thing happened to me with a htc fuze from att. they refused to warranty exchange it for me though and i had it for less then 3 months.....
Recently my EVO has stopped responding to touch inputs. It will wake with the power button but sometimes the touchscreen will not respond. Sometime I'll be able to launch an application and then it will stop. Sometimes it will work fine for minutes/hours and then the problem will surface. I've tried multiple ROMs and it doesn't seem to matter what software (AOSP or Sense) the phone is running.
Any ideas?
Sounds like it may be a hardware problem and not a software one. Have you had any problems with the LCD or digitizer?

well if its not responding then it is the digitizer. but before you dump a bunch of money into a new digitizer or new phone let me ask u this.
does it only not work while plugged in and charging? because that is kinda a common problem. as long as it works when not plugged in then ur fine.
I haven't specifically tested it to see whether or not being plugged in affects the problem but another symptom is that when it goes on the fritz you can be hitting the back or home area at the bottom and it will register the touch somewhere near the top of the screen.
Does that narrow the possibilities?
Definitely sounds like a screen/digitizer issue.
If you have the protection plan from Sprint, you can take to a repair center and they will replace for you. No charge.
Thanks for the help. My local Sprint store will replace it for $35. So we'll see if that's the issue.
Gotta flash over to stock ROM so they'll work on it though.
EDIT:
Spoke to soon. Technician at the Sprint store won't work on it. They're trying to claim there is water damage when there is none. I guess I'll have to do it myself.
A customer brought her G2 on simple mobile to me with this problem: The letter "A" wont work on portrait mode nor will the home key. I figured it was the digitizer so I replaced that with an OEM Replacement part and as soon as we booted back up the problem was still there. Could it be her OS is corrupt or possibly a warp in the case thats keeping the plate from contacting the faceplate. I'm rather stumped as I ran a logcat and I saw nothing out of the ordinary during normal input. Any help is appreciated.
Touch plate? I am confused to what you mean by this. I am not too familiar with the electronic construction of a digitizer so any info would be helpful.
The digitizer isn't coming in contact with the face plate I believe. (Sorry I used like three different words to describe the same thing in my previous post) Any tips on how to fix that would be great. I saw a video on youtube that stated a part where a heat gun would be used but I never came across a front panel (The part with "T-mobile" on it so I installed the digitizer and went along). I think I may have messed up.
i have the same problem, i dropped the phone, and the touch screen was broken, i replaced it but now the left side and home button arent worksing
ps the broken screen worked still also on the left side , did you find a solution ?
I have the same problem.
I believe it's the ribbon cable, not the Digitizer. The ribbon cables on this phone hangs between both screens and is fairly exposed at times.
I still have a couple weeks in my warranty to return it to HTC, but I can't get it to S-on. Unless I get S-on before warranty is up, I'm going to have to replace it myself.
Ribbon cables for this phone cost ~$30 on ebay. tell me if you fix it.
Any luck with this, anyone?
I have broken screen on my htc desire hd, i have replaced the LCD+digitizer before. i know my way around this phone.
Is it easy to replace just glass screen ?
I cant see how i can seprate them. they are glued in this black glue thingy.
Better buy whole LCD + digitizer?

I need to do the same. Also since dropping the phone my Bluetooth turns on and off but doesn't always connect. (highlights or ticks option , but I'm not getting anything on the top bar). I disconnect and re-connect a few times to get it working
While I have the phone apart is there anything I can do to fix it?
Sent from my Samsung Galaxy S III using Android Revolution HD
I just replaced the glass only on mine. Unfortunately, the touch screen isn't responding. Anyone know where I might have gone wrong??? Everything else seems to work fine!
Probably a Ribbon Cable.

Try taking it back apart and re-place the ribbon cables back in there seat, they may not be making proper contact. If you replaced the glass without taking it apart you probably un-seated one of the cables. When working on iPhones there is a cable that is only held in place once you close it and put the phone back together.... It's a PITA.
Buy new part and dont replace . Your self its difficult. And its not easy
You can buy a "used" DHD device to replace yours. It'll be cheaper and easier... With a backup on sdcard, your device will be the same !
Yesterday i dropped my device from one feet. It turned off and i turned it on.
Now lower part of screen and capacitative buttons dont work. i will attach a image(non-working area outlined in red)

Hi,
Only thing I can think of is that somehow it has damaged the cable from the touchscreen or the tiny wires that feed into the cable without damaging the screen. I came across a brand new screen I was replacing once for someone that had a similar problem where the bottom left hand corner wouldn't respond to touch unless there was firm pressure on the screen to create contact, and this was a brand new screen. It could also be that the touchscreen connector needs to be pushed back onto the board if it's come a bit loose.
If this is the problem, you can fix it by yourself although I'd have a good look around youtube, there are heaps of DIY videos of how to replace screens. If you do go down this path I recommend you replace the touchscreen/LCD/LCD frame in one go, as it's generally already pre- assembled the only thing here is that there are 3 brands of LCD's HTC used with the phone and they aren't all compatible, and you can only tell by pulling down your phone and looking at the LCD flex cable colours, and the other thing is that the screens that are available aren't always the same quality as the original. If this sounds to hard your best bet is to take it somewhere and diagnose the problem just in case it's something else
