What you are getting from the video out is identical to mine. The lisa DOES output a composite video signal however the sync is wrong. Everything I threw at it from Sony studio displays to capture cards simply would not sync properly.
If I can remember, three short beeps is good and if you see LOADING then chances are you got exactly that.
Second, while you got it trying to boot, the old 400K Sony drives have their lube gum up with age so it's best to clean as much as you can off and regrease it.
The analog board has several adjustment pots for the screen. You can reach them once you take the top off.
I also recommend you recap the PSU. They are old, they didn't have the best ventilation thanks to Steve they have no fan. It's pure gain of you do it. The polyesters have a habit too of making a hell of a lot of smoke.
