I have a 27/29" samsung tube I have been using with this Wei-Ya 827HR for about a year without any problems. I recently broke down the cabinet for a full restore. The monitor has no frame so chassis basically sits on a wood shelf, so the chassis was removed separate of the tube and put away. When I put everything back together and go to power up, I am getting no monitor power up, no relay click, no high voltage. Zippo nothing nada.

My checklist:
-Verified im getting 120v at the monitor cord
-Verified all connectors are in place properly (deguass, yoke, ground, annode cap, signal)
-Tested fuse on the chassis, its good
-Tested every diode on the chassis, all check out
-Pulled and tested the HOT, it is good. (compared it to a new replacement)
-Pulled the isolation transformer (built into chassis), it is good
-Tested voltage regulator, its good
-Tested for shorts to ground on the chassis, could not find any after a few hours of inspecting
-B+ pot is at its default position however I have no test point to measure B+ with a alligator clip, not sure how else to get in there safely. Maybe solder a pin on there somewhere.

I'm at a loss. Normally power problems are quite easy to figure out but I am totally stumped. Any ideas?

I know my Wei-Ya monitor was having an issue not firing up when I first got it. The tech from the place I purchased it said to turn all brightness and flyback pots / knobs down, plug it in and adjust up. Apparently one of my pots was causing it to shut down. Thought it sounded odd, but tried it and it worked. No idea if this will help, but can't hurt to try
