Broken digitizer repair - General Questions and Answers

Hi!
I have a denver 10153 quad core tablet with a broken screen. When the screen is connected, it is like there is a ghost randomly touching the screen. Apps opens and closes and keyboard is opened and a lot af a's are pressed and so on. I disconnected the screen and the tablet is working ok with my wireless keypad.
I have a hard time finding a new digitizer. The dimensoins are not the most commen ones. It is 150x252mm. 1024x600px
I have given up finding a new digitizer. But I was thunking if this one can be repaired. It has only one crack at the uppee left corner which goes from edge to edge. My guess is that the tracks that goes round the edge of the glass under the black surfice, is broken. If I can get the glass off the bezel and get to those tracks, would it be possible to repair them for instance by soldering? Or will repairing the tracks not be enough to mend the digitizer?

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?

Motorola Canada repair services (Futuretel)

Woke up this morning, check texts on my G which works fine, pocket it (front left pocket, screen facing my leg, nothing else in there, loose fitting pants), go to work, check it about an hour later, can't undo my screen lock, touch screen is acting all wonky, I'm not even touching it and I keep seeing wrong input over and over... so I turn it off and back on, but I still can't use the touch controls on the left part of the screen (the left and center row of the lock screen doesn't respond, the right most one does, and the very bottom emergency calls does).
So I carefully inspect my phone, there is not a single mark on the screen, bezel, back-plate... the phone is in pristine condition, I take good care of my electronics (or so I thought). I start checking the screen against a light at various angles and on the bottom, slightly under the lock screen dots, I see a very thin line under the glass but above the screen, starting at one edge and going about halfway across. Like the touch sensor is partly cracked, but nothing else is?
So I was wondering, does this count as physical damage? I don't see how it could. As I said, the phone is pristine and I can't imagine how I could have damaged the touch sensor without leaving a mark on the glass, bezel or screen.
But I'm still worried that Futuretel, which is where the Motorola people are telling me to send the phone will call it physical damage and have me fork over 150$ for a repair I could do myself for 50~60.
And I would do it, had I actually broken my phone... But I didn't, so I don't feel I should pay for this at all.

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.

Rebuilding a51 with new middle frame bezel

Can somebody help me. I need to buy a new middle frame bezel for my a51 and the ones online on amazon appear to be missing the big black thing that attaches to the front middle half way to the top. I don’t know what is or where to find one. When the bezel is attached it will sit by the right side of the main power cable to sub. Thanks I tried replacing my screen reattached the phone. And accidentally glued that piece and pulled it apart after reddissasmbling.
