Howdy folks!
So I bought this 720 in non-working condition...but working prior to going into storage. After looking through everything and replacing all of the fuses I could, I still have nothing. I can coin it up and seem to be able to hear it play blind. I bought a second video PCB, as I just happened to come across one on E-bay and jumped on it. My original video PCB didn't seem to light up on powering up, but this one does...in neither case did it change the functioning of the monitor. Power's coming out of the switcher and transformer okay, and checked the end of the wire going into the monitor's PCB. I've replaced and reseated all of the wiring. I also removed and replaced the flyback, just in case there was something loose there. I'm not even getting a glow on the neck, and no humming whatsoever from the monitor...no arcing or anything. What do you guys think I should try next? Replace the caps? Flyback? All of the above? Keep in mind that even though I'm using all of these terms, my knowledge is EXTREMELY limited...only what I've picked up over the past few months. Thanks!
