This gameboy was gifted to me from a Family member who found it one day in their Attic. I’ve tried fixing it a year ago, but since some parts never got delivered, it kinda slipped out of my mind until now.

The main thing I’ve replaced where the crusty green battery Contacts, but it did not seem to help with the original issue.

Upon turning it on, a bunch of stripes appear and then quickly disappear. Sometimes the whole screen is stripes, sometimes only 1-3. With disappearing I mean that they oddly seem to disintegrate in a very unnatural way. Its less pixels turning off, more like a liquid esc thing if I had to describe it.

How fast they stay and start disintegrating is dependent on how high the contrast is set, with it all the way up causing them to go almost instantly. With the contrast all the way down, on very rare occasions, I can see a corrupted Nintendo Logo like in the picture like its trying its best to start.

I only got 1 Game to test it all. The Motherboard inside looks a bit rough with the big metal thing in the middle looking a bit rusty. The screen board looks pretty good tho. I could not locate any leaking Capacitors, but some hard brown goo could be found sometimes. With all of that said, I can’t pinpoint if this is a Motherboard or screen issue, so I’m not sure which to try and replace, do any of you folks have any suggestions? Thanks
