The B+ on one of my GO7's is measuring ~170V, and shutting down. I swiped the potentiometer, and the voltage went back to 120V, and the monitor came back on (scrolling and washed out colors?). I powered down and back on, and it was back at 170V. Adjusting the pot doesn't fix it again.
The transistors measured OK.
Following the flowchart, it seems that I may need to replace IC 501, though I haven't removed transistor X701 yet.
My question is - is this just a bad pot, or does this behavior indictate that I should order an IC 501?
Thanks for any tips. I just want to have the parts I need available before I start working on the board.
