Sure is!!!!

They only go in one way, if you check your work. Something I did not do correctly.

Fixed it!! Stupid me. I put the VR transistor in backwards, and the pins were shorting against the chassis. I looked at everything, and checked the transistor, but found it shorted. Looked at the pins and saw that I put the transistor in upside down, and the pins were shorting. Reversed it...

If you read my previous post, my GO7 board, at the VR is putting out 165 volts DC. I did the full on cap/flyback/fuses/HOT/coil, etc, and still cannot regulate the voltage down. Anyone have a board to swap or for sale. I am getting so busy at work, I do not have too much time to work on it...

There was a mention of changing R512 to 80K ohms instead of the 8.2K ohms. Would that help anything? Trying to figure out what could be wrong.

Bump up. Really scratching my head on this one.

I recapped, re-flowed, changed HOT, Flyback, fuses, checked the board with a magnifying glass. Put it back in. No Go. Turns out, the voltage at the emitter of XO4 is 165 volts DC. It cannot be adjusted down with R909. I checked 909 and it is linear. What could be causing the voltage to...

Have a missile command, Atari. Has a G07 monitor. When I got it 10 years ago, it worked fine. After a while, the screen would not light up unless you turned it on and off a few times. A few times turned into a lot of times, and now, the monitor shows nothing. I am an old pinball mechanic...
