Check using the 23-pin video output and the HD15 (VGA)  connector of the Indivision simultaneously. If stock output is good and Indi is bad, remove and reseat the Indi, and check it's ground strap. If built-in video output is bad... Well then you have other problems, lol. ;)

Actually, probably a good idea to just remove and reseat everything. I know sometimes the Denise->Indi->motherboard stack can be a bit tricky. Also make sure nothing is shorting on the top of the stack, etc.

Hrm.  Any memory expansion in the trap door?  Try removing it?

Is it a Rev. 8 motherboard with a possibly leaky battery?

There's always the old "Agnus drop test", haha.  ;)
