After screen replacement touchscreen is not working - Honor 8 Questions & Answers

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?

My touchscreen became silly

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.

[Q] Desire S LCD/digitizer problem

Hi Guys,
I have little problem with my Desire S. I have recently replaced the digitizer. After fitting it and checking the phone i discovered that top area of touch screen isn't working. So I took it apart again and accidentally broke the LCD. So I ordered LCD and digitizer as one unit from ebay, fitted it.....And LCD is working fine, but new digitizer isn't working properly. I'm pressing bottom half but its registering touch in top half. Also for buttons at the bottom don't work.
So I plugged in old digitizer and it works ok apart from that faulty top area.
I had it sent over to some repair shop and they tested it with LCD/digitizer as one unit with same fault. But my old digitizer works.
Any ideas?
Thanks
Marcin

Replacement Screen Problem

I cracked my screen a few months back, and right after it happened I bought a new digitizer to replace the cracked one. The install didnt go very well, since the tape used to adhere the digitizer to the LCD got mangled during removal of the original digitizer. Dust ended up getting between the LCD and Digitizer etc. One other problem I ran into was that the LED's that are supposed to illuminate the home/menu/back/find buttons were now shinning up into the screen and washing it out.
Anyways I got fed up with the dust and bought a new fully assembled screen/digitizer off ebay. I installed it last night and everything is great except that the lights are still shinning up through the glass and washing out the lower inch of the screen. I dont see why this would happen as there is really only one way to put it all back together.
Any insight as to how to get the lights to stop doing this?
Thanks!

Screen unresponsive, partially dead

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?

Touch screen going crazy

Hi guys,
I have a Dasaita PX5 unit with Android 8.0 and 4 GB RAM.
I've bought it a few months ago and it was working fine until today the screen just went crazy.
The screen will start touching itself all over and enabling settings, or quitting my GPS software, or activating apps, or flipping through different screens etc.
I've tried to update the system software, update the MCU, and even a factory reset. The crazy screen issue still persist.
Any idea how and why my screen went crazy and how do I resolve it?
Thanks
Here is a short sample of what I meant by going crazy:

I know exactly why and have had the same problem. There is a ribbon cable that comes out of the screen between the glass and LCD for the digitizer, its damaged the screens are so cheaply made the glass is still somewhat sharp and the cable kinks and breaks. . I actually just came on here to post if anyone knew where I could get a replacement besides Aliexpress.....
You should try reconnecting the ribbon cable, else just get yourself a screen replacement from where you bought the headunit.
I had similar issue where bottom part of the touch screen no longer register touches and as time goes by, the whole screen is completely "untouchable".
The root cause is that the ribbon between the unit and the screen panel connect to the mainboard is rubbing against the unit casing's sharp edges causes permanent damage. Fortunately, it is still under warranty and i have got a replacement panel, smoothed the casing edges and place some duct tape before replacing the panel.
