My Star Wars upright (w/19" Amp) went down on New Year's Eve. It has been rock solid for some time, so this surprised me. Red LED on the Amp deflection board is lit. Deflection and High Voltage boards have been rebuilt fairly recently.
After some sleuthing, I found that the AR-02 board isn't showing +5v on the +SENSE test point. The other voltage test points are pretty darned close to what they should be (example: -5v is -5.1).
I've got multiple rebuilt and tested good AR-02 boards that I've tried, and they're all showing nothing on +5v.
Ideas on where to check next? Is there a way to test voltage going into the AR-02?
Thanks,
Greg
