So I purchased a switch with a cracked srceen off eBay, as I have another switch with a working screen I put the eBay board into my personal switch with working screen hoping for a quick fix.
I still have a black screen (in hand held mode) I can see the back light, the touch functions work and sound.
From what I can see it appears that no work has been done to the board.
I have briefly checked the caps around the ic’s for shorts (one probe on ground and both sides of the caps) I have not yet found any…
Any help appreciated?
