I'm working on a pair of Happ SE-M21C19's and just finished capping one of the chassis, all 50 or so caps worth. I re-installed the chassis and I get nothing. No neck glow at all. I verified voltage coming in, but that's all. I'm thinking it's the shut down circuit or perhaps a transistor, but I'm not familiar with working on this style of monitor at all. Any suggestions would be appreciated.
