The first
thing to do would be to pop the top off of the Lisa
and check the 4-5 video adjustment dials along the top of the video
board, as well as the adjustment pot on the PSU. To me it definately
Please don't!. If you have a real fault (and this sounds like one), it
will not be cured by making adjustments. Once you've twiddled everything
you will still have to cure the real fault and then re-align everything.
The only times you should adjust presets are (a) after some other person
has been fiddling about and (b) after replacing components in the
relevant part of the circuit. And to twiddle PSU presets without knowing
just what you are doing is a good way to wipe out the entire set of chips
in the machine.
