my daughter's tablet screen was cracked. A Chinese web shop offered replacement screen (lcd, digitizer & glass combo) and I ordered giving them correct model of the tablet. Now, I received physically perfectly fitting gear but I won't get any image on the screen. I can see backlight lit for a short while.
I swapped the faulty LCD/digitizer/glass back and could see picture just perfectly. So it seems like resolution issue. I even swapped the new LCD back while tablet was powered up (I know, I know..) and I could see picture in the replacement screen as well! But the image was distorted just like you've seen in CRTs when resolution/refresh don't match the screen capabilities.
Tablets model is Asus ZenPad 10 Z301M-1B006A. This site explains the differences pretty well:
w w w . p d e v i c e . c o m
Even the GPU is same for 1920*1200 and 1280*800 system.
Actual replacement LCD is NV101WUM-N52 (1920*1200).
It perhaps should have been TV101WXM-NU1 (1280*800).
I saw some web shops giving possibility to select resolution but my Chinese web shop just asked the model. I have perfectly correct model in the order.
The sticker on the replacement panel says ATAB435 and "Asus Z301M Z301MFL" plus some Chinese chars. This suggests the LCD was indeed intended for Z301M/1280*800 tablet.
Now, the question is, could my replacement screen picture problem be due to wrong initial Android bootup resolution setting which I could possibly change with adb thus upgrade the tablet to 1920*1200 reso?
Hope this question made any sense at all.
