[SOLVED] Broken FPC Connector in HDMI display

Post by salami738 » Fri Dec 22, 2017 1:55 pm

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... :oops:

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