Probably something simple, sometimes cab turns on fine, sometimes it turns on blind (sort of). No matter the pcb, I have a couple that work fine in friends cab. You can here the hum of CRT but no image. Now when you turn off, cab you get a very brief flash of colors like turning off a tv and also CRT tube glow. I took a video but it won't let me upload. I attached some screen shots of the paused video and you can see that there's an image as its turning off, it's just not displaying! Thoughts? 25" std res qnic cgm2500 chassis.
