It looks like its been recapped and worked on previously. No indication of anything on your flyback to me either. I'd leave it for now.

The dark burned up area inside the heat sinks looks like parts have been replaced there too..(maybe the resistor burned up? the one that's there looks new and the source of the burn marks.

Put the H/O transistor in and try it is my suggestion based on what I'm looking at...
If it works - I wouldn't replace anything else..
Hopefully you get the part today.

vapuser:
Sounds good. Sometimes it feels like we're involved with a crime scene investigation. What component did it and why. too funny. I believe those parts will come in today or tomorrow.

bperkins01:
Some of it is CSI work.. But those NTE Caps all look new, I think they have data codes on them... But I'm not sure..

vapuser:
I had a chance to replace the H/Out last night. I'll also replace that mini fuse and put everything back together as you suggested. Hoping to see some life with this monitor so I can check the B+ and make some final adjustments. I'll try to get back online Saturday to give another update.

vapuser:
After, replacing the H/out resistor and mini 1 amp fuse, I put everything back together and placed the monitor back in the cabinet. I turned the power back on and still no difference. The mini 1 amp fuse blew again and still no power to the monitor. I thought for sure that would have worked. I ordered a Fluke 15B + F15B+ Digital ohmmeter today. That should be here in a day or two. I'd like to re-test out that H/out transistor again and maybe the voltage regulator (2SC1106) transistor? Something must be blowing that mini fuse. Just not sure what it could be. Any suggestions? :dunno
