So I'm posting here as a bit of a last resort as I'm at a dead end with getting this console working correctly. The initial problem was the blinking power light issue, but that was solved by correcting the height of the cartridge when it's pressed down. The current issue is that the output from the console is either a frozen menu screen
at varying positions on the screen, solid-colored screens, or random artifacts
as shown in the linked images.
I've tried all of the usual fixes that seem to be on different guides and videos, including:
- Cleaning all of the contacts with rubbing alcohol on both the game, the 72pin connector, and the contacts on the board for the 72pin connector
- Bending the pins of the 72pin connector up and boiling it
- Disabling the lockout chip
- Visual check of all the components on the board
Cleaning everything seemed to get the best result as when initially powering on the console i got the full title screen of Golf in the correct position, but it froze up again. I clipped the pin of the lockout chip so I can bridge it to revert it if needed, but it didn't seem to make a difference. The only other thing I can think of is in the area where the power input and outputs are, a component
seems to be getting very hot when it's powered on. I'm assuming the piece of metal getting hot is a heat sink and it's just doing its job, but I figured I should add it just in case.
At this point I feel like I've tried everything I could find, I can't seem to find any guides or reddit threads that list any other solutions, so any advice would be appreciated. I'm sorry if this isn't the right place or if I'm posting wrong, I had read through the newcomer post and tried to include as much info as I could, if I'm missing anything I'll try to add it as soon as I can. Thanks again.
