Yesterday after I took out my touch pro from my pocket something happened. My touch screen didn't work. I don't know why.
I thought a flex/ribbon cable don't connect so I took apart it. Everything was right. I removed the Digitizer ( plastic over the T.screen) and tried out the screen it didn't work. I inserted the Digitizer back the phone feels my touch but isn't there where I touch.
So what can be wrong? Digitizer can cause this problem because of scratches?
I hope you understood my problem and you can help me. I am not an English man.
Uh, did you try screen alignment after replacing the digitizer? I can't imagine that it'll work still after taking off the digitizer and replacing it. I'd probably say best to just replace the entire display.
I tried screen alignment with a new rom. After that I had known
it is a hardware problem. But I don't know the touchscreen or the digitizer is wrong.

Hi,
I have just replaced LCD and digitizer of my HTC raph (first time) and there seems to be some kind of problem. It turns on, but the screen shows nothing just lights up a little bit and there are some stripes visible as if the lcd would be broken, but it's brand new. The stripes changes a bit as i press some buttons or touch the screen so the phone and touchscreen are working - the problem is with LCD.
I don't know if i put all the conducting tape to the places it originaly was. Could that be a problem? I double checked all the connections but still, might be a contacts problem?
Any thoughts on what might cause this?
Also the phone got kind of hot after having it charged for some time, is that normal?
Of course, this may be caused by a bad connection (but rather hard to go wrong slot), but at a distance hard to say something more concrete.
Best to check with the new flex.
Thank you for the answer, i will try changing the main flex.
The flex cables can touch eachother right? Since they're originally covered with conductive tape.
BTW, i also intend to change the lcd + digitizer... my question is:
how to apply the digitzier? lcd and digitizer came separated - do i have to solder/glue or whatever the flex (of lcd & digi.)?
The original was something like sticked together... reminds me on sellotape aka Scotch Tape.
Can you give me a some help?
thanks
The ribbons must be solded together, there's 4 contacts on them and they should not touch eachother.
So I've got a relatively cheap used sensation off ebay. It was announced defective and it was stated that part of the screen is dead. So I thought there were some dead pixels which didn't seem much of an issue for me. However, there are no dead pixels, the screen looks fine. However, it is very unresponsive. I have trouble pulling the ring to unlock the screen, selecting icons, typing, ect. There is also one part of the screen (one whole row) where the screen is completely unresponsive (doesn't react at all when touched).
Tried the SGS screen booster, tried cleaning the metal contacts on the battery side of the phone... nothing worked. The phone still has it's warranty seal, so it doesn't seem to have been opened..
Any suggestions other rhan faulty digitizer?
Thanks for your help
Sounds exactly like a faulty digitiser, which is costly to repair unfortunately, although it it surprisingly hard to break them, recently smashed the glass on mine, and the touch still worked perfectly!
I just asked the seller what made the touchscreen to stop responding. He said the phone fell off, hit the ground and afterwards the display wasn't working properly. Maybe there is some other way to fix this? The digitizer itself is not broken.. maybe there is something that got displaced.. or maybe there is a faulty connection somewhere on the pcb... do you have any suggestions? Thanks!
just noticed that if I squeeze the phone top to bottom (i.e. grab it with the thumb onto the unlocking latch for the back cover and the middle finger on top of the phone, just above the speaker) it opens 'messages'.. So maybe there is some bad connection on the pcb? Or should this definitely point to a faulty digitizer?
Hi all
My moto Maxx has gone through a lot, but the strangest problem yet started yesterday.
As you can see on the attached video, half of the screen is constantly scrolling. This happens in fastboot and recovery mode as well, so I'm pretty sure it's a hardware problem.
The digitizer still works perfectly, and registers touch where the icon or button should be positioned on the screen. The moving screen also does show everything correctly, just in this crazy scrolling way.
I'm not very hopeful in fixing it, but was wondering if anyone has ever seen this, and if you guys think this is a broken display(and any way to test this?) or a broken GPU. If it is in fact the display, I might consider replacing it.
Some background on all the terrible things I did to this phone:
- Dropped it and cracked screen in September.
- Replaced the glass myself, slightly burned display when removing glass without any consequences (just a tiny mark on the top right, the side that actually still works).
- Dropped again, broke glass again, never bothered to fix it, some small pieces are missing so dust, sweat,.. could've gotten int.

Most likely the display being broken.
Even when my tempered glass protector is missing chunks the screen starts to funk up. Only worse being the real screen especially the digitizer.
You might be right pjd, or at least screen related.
I opened it up yesterday evening, and I think it might be the cable connecting the screen. Depending on how I positioned the screen and thus the angle at which the cable was bent, it was fixed, the same, or just completely black.
The only thing I have to try to find out now is if it's the kabel, or the connector on the motherboard. Any suggestions on how I could test that are welcome!
I did something really dumb and took a hot shower with my phone in the bathroom. I think some vapor got inside the phone and shorted the digitizer (touch panel). Everything works still, including the screen. I have to use a mouse to control my phone. I hope someone can help me.
You know that the S6 is not water resistent? So technically it's your fault that your Touch Screen doesn't work anymore. And when the Hardware is damaged the only way is to replace it. There is nothing anyone here can do...
I changed screen assembly to my boys Honor 8. All went well.
Not so nice job BTW.
I tried that the screen was working but didnt tested the touch. I reassembled it and noticed that the touch is not regonized.
Does somebody have any clue or is the assembly just broken? :crying:
Likely you didn't connect the digitizer, or the digitizer is broken. Touch won't work without digitizer. I don't know how to fix it, you may have to look it up, maybe Ifixit has a guide. You may need to buy another digitizer for Honor 8.
Problem solved. I detached screen again. In bottom of the screen there was digitizer connector. It looked OKAY but I disconnected it and but it back firmly. Touch started to work. Yeah baby ??
Nice. Was I of any help?
