Today, I had my second try, and it worked out pretty well, with one exception, the shitty quality of the front light kits.
I ordered three of these kits and two of them have these spots. They can't cleaned up.

But at least, my brightness control works fine :-)

I tested the LCD with the pcb of another Gameboy, it didn't make a difference.

I've broken maaany GBC screens. It's likely a small section of it could have chipped/snapped during reassembly, or you've damaged the ribbon cable. Though perhaps it's some kind of issue with the modifications to the board? Test it with a different screen

Hi everyone!

Today I tried to add a frontlight to my GBC LCD as well as the brightness control pcb I've made, no need for potentiometers anymore .
I used Osaka 6 LOCA and a 10W UV LED for curing.
Well, my pcb is working very well, but the LCD isn't working anymore.... It's just blank when switching on the Gameboy, sound is working.
I can't figure out why, there are no mechanical defects. Maybe the LCD became distorted while curing?

In order to save time, money and LCDs, does anybody have some helpful advices, please? BTW, of course I followed these instructions.
