Hi,
I have the HDMI 3.5 inch 480x320 display with a controller board:
There is a string on the FPC cable, backside: FPC-QD350C48001V1.
Today I noticed that the lcd backlight turns on and off at random times and it flickers. I opened up the case and when I move the panel, the problems became intense. I marked the lanes that are used for the backlight.
Is there any way of fixing a broken FPC cable? Don't want to replace the whole display with controller board...

You can try to solder a wire to replace the broken path !
Find the starting pad and follow it to the end.
