No Picture on 7th Gen Ipad A2197 (Backlight On)
Hello, I have a customers A2197 Ipad that came in for a charge port replacement.
The person broke off a charge tip in the charging port and tried a bunch to fish it out. Maybe he could have shorted something?
# - I replaced the charging port but now the LCD has Backlight and NO Picture.
# - The ipad boots up now and you you can hear music from apps running.
# - I orderred a new LCD and that doesn't show picture either. Just backlight
# - Ive inspected for missing components (Fail)
# - I used ZXW the check the readings on the LCD connector and they all seem ok except one reading that should be 1.69 is 2.78
Would appreciate any help...
Kevin
Answer:
I knocked off a filter when i was removing the antenna wire.
But as you can see... it is somewhat of a design flaw.
They put the antenna clip very close to the image filter.
They glued the antenna clip in place so it cant knock off a filter on its own.
Getting the antenna off with the glue makes it easy to knock off a filter
Perhaps i would use some rubbing alcohol and some heat next time i try to remove this antenna
