GBC display - every other line is dead

[Released: 1998] As suggested by the name, features a color screen. It is slightly thicker and taller than the Game Boy Pocket, which is a redesigned Game Boy released in 1996. As with the original Game Boy, it has an 8-bit processor and the custom Zilog Z80 central processing unit.

GBC display - every other line is dead

Post by /gbColor »

TLDR, I found an old Game Boy Color when we helped my mom move, and I still had my OG copy of Pokemon Blue. They both booted right up, and I got about 15 hours of play out of them without issue.
I picked up the GBC after it being off for about an hour, and the every other (horizontal) line in the display is missing. I can’t find any old threads about the same issue, and I had not previously opened it up, or tried to modify it.
I tried the contrast dial, dug around inside, cleaned up the board and contacts with a little alcohol, and spent an hour trying to find ribbon cable breaks or corrosion to the screen - no changes. The issue is present with or without a cart.
I’m about to toss it in the trash - any ideas, tips, or tricks for this?
