What to check next? Did you clean board really well? I Usually pull the chips off that are in sockets and clean board and legs of chips etc. |

Hmm that’s a strange display pattern.
Tested the RAM? Can cause video gremlins. Worth testing both banks individually too.
Checked plugs on the analog board for cracked solder joints? Usually causes black screen or wobble symptoms but worth a look. |
