I'm working on a monitor of course a MS8-26SU Nano. The monitor works for 10-15 seconds.. gets a picture and shuts down. I hear a click on the chasiss.

I need a schematic if anyone has one.

My thoughts are:

1. Someone has it running at 120v via iso xfmr. And its a 100v monitor. I'm thinking this is my problem.

But I need a schematic.

Has anyone have a clue where I should check first. i.e. get a new flyback , hot transistor. etc.

pretty sure if this is a sega type 100v monitor as mentioned. Id start there , know anybody with a variac you could test your theory that way tap into the isolated power and crank it down to 100vac and recheck monitor operation. If it works, well, theres your prob.
