3 options.

Or
Just bite it, take the chassis out and send it to buffet.

I've done the cap kit, flyback, and HOT....what's left? some other caps that don't get done in the cap kit? Other pieces that I'm not sure what they are called?

B+ is putting out about 128v to 130v. I am assuming that should be adjusted down. That needs to be done while on?

Yes, it's easiest to adjust while on. If you are afraid, you can turn it down while the monitor is off. Turn it on and test. Then, turn it off again and adjust pot accordingly if needed. Rinse and repeat until you are 108V. |

Adjusted the pot and it still hovers around 130v.... voltage regulator? Q901? This is quite the learning experience.

Apparently he is a monitor wizard!
So I have learned how to test a pot and I think I have determined that the pot is bad and basically completely open with no resistance. Time to get a replacement and cross our fingers.

Ok...I've calmed down. New IC601 voltage regulator coming and a new transistor for Q901. Both coming from Twisty Wrist Arcade.
