[Q] touchscreen problem

Wife dropped phone into cup of soda. Only damage was little bit on lcd and camera. Fixed camera and replaced lcd but now the bottom of touchscreen is not working. Tried resetting phone and such yet still doesn't work. Does the touchscreen need to be replaced as well?

You probably shorted out the digitizer so yes you need a new one

Ribbon wire connector and funky screen discoloration?

My G2 has been out of commission for a while now, it had been getting this green/red screen discoloration and eventually went black and wouldn't display anything until just today. I played around with the ribbon connector a bit and got it to display again. My question is if I were to open up my G2 and connect the ribbon better or replace it entirely, would it be possible to breathe new life into this old phone? Answers much appreciated.

if it is exactly as you said, then it might justmean that the ribbon that connects the display to the board probably came loose... or is busted.. so replacing that ribbon might do it.

Phone slammed on Ground.. Is mother Board dead?

I Received a Phone that was slammed on the ground top part of phone was bent.. Screen cracked and wont turn on ..front camera and proximity sensor broken also...
Purchase new lcd and digitizer and installed it and phone still will wont come on...
Is there a way i can check if the motherboard is dead???

Is think the motherboard is still working when the PC recognises your phone. Not sure, but I think I'm right! At least worth a try

Experts: How to check if a digitizer works before full assembly?

Hey guys, after doing some research, I've found out that if the correct adhesive is not used ( a pain in the butt ) there can be digitizer issues.
I was sold a bad, completely unresponsive, digitizer, which I only found out after taking forever tear it down and put it back.
When the new replacement digitizer arrives, will I be able to test if input works without seating it into the phone front panel and without touching the LCD?
In other words can I just plug in the digitizer into the MB to test before assembly and be able to click on it solo after I turn on the phone?
Or does it have to seated, and also adhered properly?

You can plug it in and test it without glueing it in. Just be careful and hold it close to the phone without damaging the LCD. Touching the digitizer you will see the movement on the LCD screen.
Make sure it works before glueing it down over the LCD.

Red Screen after LDC Replacement

I have an original Nexus 7 bought right when it came out and have not had any issues with it. Recently the glass was cracked so I purchased a touch screen and digitizer and decided to replace it myself.
Things went well , only had a little difficulty separating the bezel adhesive but did get it off successfully. Connected everything and reassembled easily but when powering on the screen is all red background instead of black. Can see the Google logo in white clearly and the boot animation but everything that should be black is red. I rechecked all the ribbon cables and everything is secure.
Any ideas as to what the problem may be now? Could it be the small LCD to motherboard cable was damaged during removal and needs replaced?
Thanks for any help.

Well I just ordered a new LCD to motherboard ribbon cable off eBay for $8. I'll report back of that fixed it or not. If not time to save up for a new one I suppose.

I am happy to report that replacing the LCD to motherboard ribbon cable solved my issue. Hopefully someone else will find use of this one day.
