Hi everyone My SE/30 Chimes and boots(can see bluescsi flashing). Originally no screen but I've removed and cleaned UE8 LS166 and UF8 LS393 both had cap goo under and now I get what is shown in pics. 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.

Yes I have cleaned everything might need to be ultrasonic cleaned

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.
