Good morning! Sorry for the long post, but I wanted to be as thorough as possible with my description!
Okay, so I just replaced the (cracked) digitizer on my Tab 3 8.0 (SM-T310), with a new one (actual Samsung part, not generic), but now touch screen doesn't work... The old digitizer/touchscreen, despite being cracked, still worked okay before I removed it. I had to eventually buy a new digitizer, because the cracks were starting to get bigger. I managed to replace it without breaking anything else, but now the touchscreen won't work. I'm not yet sure if it's D.O.A., but before I call the vendor for a replacement, I just wanted to see if there was anything else I could try.
Background and troubleshooting already performed:
- I checked other posts on here with similar issues, but no solutions unfortunately.
- All physical buttons (Power button and the Home button) work okay, but the swipe screen, menu button, and the back button don't work (tablet boots up fine, but I can't unlock it to access my homescreen).
- I checked and reseated the cables (and the battery), no go. Especially made sure that the digitizer cable was correctly and firmly attached.
- Made sure the clear plastic protector on the new digitizer had been removed and the glass was cleaned.
- LCD was not damaged during removal of faulty digitizer (and during removal of all that glue!). Also made sure the LCD itself was super clean.
- New digitizer is an actual Samsung part, not a generic one. No physical damage on it that I can see.
- I can't check to see if the old digitizer still works, because when removing it from an lcd that has glue all over it, the whole [digitizer] glass cracks and literally turns into powder! Good thing I was wearing goggles!
That's pretty much all the troubleshooting I've done... does anyone have any other suggestions?
In addition:
While googling this, I saw a forum for another type of [Android] tablet (forgot which one... not a Tab): After digitizer was replaced, touch screen would not work, but after reflashing the firmware, or updating the touchscreen firmware (can that be done?), it did. Is that something I would need to do also? If so, how do I do it with PC only if I can't access any settings on the tablet?
I don't mind at all if this results in a complete factory reset... as long as the touchscreen works again!
(Side note: I've replaced cracked digitizers on a Galaxy S4, and Note 10.1, I've never had to update any firmware.)
Lastly, does the whole area of the digitizer (glass and sides) have to be in full contact with the LCD itself (i.e. no air bubbles between lcd and digitizer)?
Thank you very much in advance! And thanks also for bearing with the long post!
