About a year ago I acquired a working but very washed out monitor that has JC-TRON screen printed on it. It came with an imperial monitor manual, and others have helped me determine it's a re-branded Kortek, something very similar to model KT-1420A, just a few components out of place.
In typical fashion I put on a cap kit and replaced the filter cap, plugged it in and it was still a little dim so I adjusted the screen control on the flyback and had a beautiful picture...for about 15 seconds. Something near the flyback smoked but I didn't see what. I pulled the chassis, realized that I put a could capacitors in wrong. Yeah, let the snickering begin. Anyway, after I fixed that issue I installed it and turned it on just to humor myself. It's now totally dead.
It's been sitting there ever since but I need to get a width coil for another chassis so I figure now would be the time to troubleshoot this one. I don't have a ring tester to check the flyback. I'm happy to rip this thing up and test every component given a little instruction. Where to start?
