Very new to this so please be gentle.
I've picked up a SE/30 which chimes on power on and has hard disk activity but the CRT shows no sign of life. I have read through the documentation that I can find and I am pretty certain I am looking at some sort of analog board problem. There is a lot of blackish residue across the inside top of the case, the fans and the top of the CRT. The flyback cable has sticky residue at both ends. I have visually inspected the back of the analog board and It looks pretty clean with no obvious issues.
Not sure where to go next to try and narrow down the problem?
