I was watching it and the pic started to flicker. Now it is black with an occasional flicker and the scan fail led is lit. I changed both the vertical and horizontal boards and no change.

Check the 17 volt line to see if it's still at 17 volts. Are all the yellow LEDs lit?

I will check the 17 volt and yes all the yellow LEDs are lit.

I have parts if you need them.

Scan fail can also be caused by the power supply, either video switching board, the H shift board next to the H board, bad yoke connectors, yoke switches.

I finally got a chance to check this thing out. The voltage was 17.6 volts. I set it at 17 volts. Not sure if that was off enough to cause the problem or it was something else. It has been about 3 weeks since it was on. The scan led is off but all the adjustments were all out of wack as well. I spent some time adjusting things. Even had to adjust the master H width trim pot. But it is now working perfect and looks great.
