Neotec 2701 in a San Francisco rush that had video that was barely visible. With brightness controls cranked up, you could see faint video in a nearly black screen. Tube tests ok (not great, but should give a decent pic). Chassis was capped and flyback replaced, no significant improvement. With the brightness cranked up the picture is very dark with no colors, it looks like a photo negative in black/white. Any suggestions?
 
Any bright ideas?

Test all transistors on neckboard. A shorted driver transistor will
create this effect on a Neotec.
