Hi, I received a switch to replace the usb port charging. After reassembly and turn on appears some coloured stripes in the screen. Disassembly again and noticed some pins of the LCD FPC were bended. Replaced then the FPC connector.
Then try to turn it on and just working backlight, no image. Connected to windows shows APX at connect time (disconnected and reconnected battery in every try). Then disconnecting the LCD show Nintendo Switch in device manager instread APX so I supposed turned on properly bad something wrong in any LCD board line. After retry with LCD connected and disconnected, now always show APX.
Somebody can gimme a clue what to measure aroung LCD IC and FPC?.
P.S. LCD is OK, tested with other board and FPC soldered checked with microscope, al pins right soldered and no tin between two adjacent pins, anyway tried to switch it before resolder the FPC and show APX as well I suppose withouth screen can boot up properly...
