Spent a few hours of quality time with my Tempest monitor today. I applied most, but not all, of the Bob Roberts standard cap kit. New caps on the neck & HV boards, chassis transistors, and resistors. I avoided some areas that looked like trouble. Some real top notch work done to this monitor, which has a number of burnt traces which were repaired with globs of solder or clipped off component legs. Cleaned up some of the sloppy work. Replaced F100/F101/F700. The mounts for Q605 & Q606 had one broken wire each. The red wire from the HV molex to the neck board was broken. I resoldered it all.
Original symptoms:
I fired it up expecting a picture after all the work, but I've got nothing.
New symptoms:
The fuses are all okay. Poked around and saw that the patch to Q606 had come off, but that would kill at most 1/2 of the picture, and I've got nothing.
What now?
