Replaced the screen on Kindle Fire HD8 6th. After putting back together certain parts of the screen don't respond to touch.


Sometimes the flex cable that connects the touch screen comes lose when reassembling. You will need to take it back apart and check all connections. If the flex cable is fully set then there are two things that can be wrong.

1: The screen and or cable is bad. The flex cable is very fragile and can tear easily. Inspect the flex cable for small tears or sharp folds. Also look for missing components on the flex cable.The solder pads are shiny if none was there and dull if there was something there

2: The pressure connector on the motherboard is broken or not fully seating. Look at the pins on the back of the connector to see if any part of it came loose. You may need a magnifying glass to inspect it.

If all looks well then it may be a bad touchscreen.

My Acer Iconcia ' A1 will not come on at all.


Possibly the ribbon cable that goes to the screen came lose from the main circuit board. I suggest you find a YouTube video on disassembling your tablet and watch it. Where the ribbon cable attaches to the board, there will be a fastener that holds it in place that either slides out or flips up. It won't look like there's any sort of fastener there so make sure you watch the video that shows how it works.
In the video I've linked, one could get the impression that how you unfasten the ribbon cable latch is up to the user (slide it or flip it up) but it's not your option. It depends on the design of the connector.
