Nice…..turn down the screen control for the blue picture tube, located up front under the front grille and the grille behind it…Get a T-10 torx
it’s going to be the control on the left or right. and don’t mess with the others without putting them exactly where they were.
It could be a shorted blue CRT too..
Or a CRT output transistor…
Could be missing 200 Volts supply….
Might even be coolant leaking from one of the picture tubes onto the blue crt or the 200v….that’ll take out your main power supply within a couple weeks.
