After recapping monitor it was working fine for like the 5 min I had it in cabinet. Then started playing blind so brought back to bench.
Swapped in known good p317 and it worked fine so know the issue is there.
Read the flow chart and some threads. Turn up screen and get white raster with retrace.
tested TR201 and TR202 good but replaced them anyway to be 100%. Still no pic.
Tested VR201 good but swapped out just to be 100%. Still no pic.
Can't test zd201 (easily at least) but guess I could pull it from working board. Calls for a 6.8v 1/2 watt zener. Looks like 1n754A or 1n5235B would be replacements.
I also have a 1n4732 which is 4.7v. Guess I could recheck the caps too.
Other thoughts?
