Hi, just scored an old barcodata CRT projector off a friend for free, apparently according to him it had an issue with its powersupply. I've had a look at the crt's they look pretty good, no evidence of burns. Now the problem, it powers up, I get a high pitched pulsing sound, for a few seconds, the fans come on, and I can see a browny glow coming from the back of the CRT"s where they connect to the rest of the circuit. When I hookup a video source I get a green LED, I have 6 amber LEDS, only 5 of the 6 light up, the one of the top right hand side fails to light, I haven't determined if it's a dead LED or not yet. But I do get the red one, which i've learnt indicates a scan fail, which is normally related to power supply problems? I just waiting on my friend to drop off the controller that plugs into the back, but I doubt this would be the issue. CRT tech is all quite new to me, so i'm finding this exciting working inside one, as i've never touched one before.
