need help - touchscreen fix

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
Got a headache? It's all in your head!!!

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.

I think I destroyed my HTC One X

Hey guys,
I think I destroyed my HTC One X. I just bought it a month ago from Ebay, and it worked flawless. At some point the display just turn off. I restarted the phone, heard the sound when it starts and even the softkeys worked. But the Display was still off. After after a few restarts the display turned on for a minute, just to freeze after that and turned off again. The phone was still on though.
However I've read a bit around and found out that it could be a cpu heat problem, which could be true because my phone was way too warm sometimes. So I removed the display and put a tiny little bit thermal compound on the cpu. Somehow I managed to rip off the connection cable to the display ... also I managed to rip off the little black cable near the soft keys. The soft keys still work though.
When I start the phone the starting sound comes, the softkeys blink when I restart the phone, you hear the volume buttons etc. So it seems the phone is fully working. Just the display or touchscreen is damaged.
Some pictures:

So, what can I do?
Do you think I could just send it to this site http://www.directfix.com/product/REP-0063.html and let them repair it? Or did I destroyed my phone too much already?
Thanks in advance.

Well,the top cable is ripped off,you can't do anything at this point.The bottom one just seems out of slot as far as i can tell from the pics.
Basicaly you can send it to the repair shop,but i don't think that you can only change the cables,don't really know what to say...Could cost you some to repair it.

I don't want to only change the cables. I want to use this full repair service:
"HTC One X Complete Screen Replacement Service (Includes LCD & Digitizer)".
So they change the cables and put on a new LCD & Digitizer as far I understand.
But do you guys think they will put back the other cable back in slot too?

Please just answer, do you guys think they can repair it if they put on a new screen & digitalizer?

I don't see why not,you can also contact them and explain them the situation.Those cables are quite easy to put back with the proper tools so you don't have to worry about it.

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

Not so usual screen problem

Hello guys, after screwing up my phone I'm using my tablet a lot more. So i'm experiencing some problems. The screen problems increase when i use the tablet more often, but i don't have this phantom touch problems it's actually the screen stop working. It just stays on lock screen and me unable to unlock it, i restart the tablet and still doesn't work. However the strange part is that when i hit the back of the tablet in something it immediately starts to work??? I know about the N7 touch screen issues, but i thought they were software based? But mine looks like it's hardware problem? Can you explain me and help me? Thanks.

Can somebody answer me??

If it's hardware, it's most likely, though not exclusively, the cable connections. You need to take the back cover off, and reseat them one by one. Takes a little work because there are 3 cables, one with 2 prongs. Reseat all of them if you can since you don't really know which one caused the problem.

Warranty?
Ok i saw some videos that it may be replacing the screen cables just as you said, but i have warranty. What to do? If i take it to warranty center it's most likely it will work there at the moment? It stops in random times.. What to do?

Removing the back without voiding the warranty is very simple but make sure that you will wear some sort of protective gloves and not touch any copper foil at all ( or you end up with finger prints.. ). Simply reattach the touchscreen connector cable only and you´re good to go.

Thanks for the info. Actually i can fix it easly not by hitting, but just by pressing the back cover. I saw where the cables are in a video and can permanently fix it by putting something between the back and the cables to keep thwm in place. And when i press they just go in place. For now i will just press it when needed. If the problem increases i will open and reattach all cables in place. Thanks for answers.

[Q] Tab S signal loss and reset problem

Hi,
My t705 has found a new problem.
It constantly loses mobile signal and brings back the signal a few moments later.
At the time when the signal is lost, if i touch the screen, dark bars appears vertically on screen and vanishes in a blink of eye and if i continue touching and working with screen, the tablet resets.
Not to mention I have no problem if the device is connected to the power source. I mean when it is charging, the device is working perfectly. When i disconnect from the charger, the problem rises again, no matter at which level the battery is charged.
I tired, safe mode, removing sim, selecting gsm only, wcdma only, factory reset, removing sd memery non of the seems to fix the problem.
I am using Android 5.02.
What do you suggest?

I have the same problem too, is it due to battery problem?

I found the information in the link below, it says it`s for the T800and T805, But it should work for the T700 and T705 just the same, be careful i take no responsibility for any damage you do.

random reboots and green line flickring
nothing going to work as its a hardware problem
replace the tab asap
and if u void ur warrenty than go to any good mobile repair shop
nd ask them to solder ur battery connector to the motherboard
this is the only nd 100% working solution

How can it be a hardware problem if it happens only after software update?

Im currently having this problem as well. It happened to me before and after the lollipop update. I thought it was the battery so i went to buy and install a new battery.
The flickering lines and mobile connections resets have stopped but now it just randomly shuts down and cannot be turned back on unless being connected to a pkwer supply like a wall charger or a power bank. I have not yet found a solution to this problem.

Could you provide more details about this solution? Like pictures of the connections or just descriptions will do. My device has been knox-tripped and i think claiming warranty wouldnt do anything. I didnt expect samsung to make such a faulty device which has crappy connections which fail within a year. ��

I opened the back cover and disconnected and reconnected the battery connector, seemed to solved the problem for a day or less but then again it came back. Not to mention i broke part of the connector while disconnecting it and now the connector does not connect to the motherboard easily, unless I press it hardly. I fixed the problem by putting a thick peice of paper between back cover and connector.
But our main problem is still there. So you say we can solve it by soldering the connector to motherboard?

It seems to be common for Samsung Tablets for the display connector to become loose and even come unplugged due to an drop or bending of the case while no damage to the outside is evident.
I suppose the power connector could come loose as well, there are a number of video`s on Youtube of the connector being off, when the case is opened.
John.
Below shows how to replace the battery on the T705 , Video`s for other version as available.
I can find the battery for my T800 on Ebay for £9 and the pry tool for £1 , or you can pay $60 to newpower99 for the whole kit.
