this monitor came to me from a friend to see if I can repair it, mi friend doesnīt know what happens to it or any simptom.
I pluged the monitor and switch on, aparently the power supply works, the front led ligths green, the desmagnetizer coil work for a while, after a short period the front led comes ambar, i have no signal of HV in the crt (no scratching noise)When I switch it to the PC the front led goes green, the rgb cathodes on the crt neck goes on, the rgb signal is present in the crt pins, the sinc signals are present but theres no HV in the out of flyback. As I cant get the schematic I dnt know where to start looking or a signal to follow. I ges that without signal the flyback goes off and when the monitor detects signal (maybe vert or horizontal sinc) the flyback goes on. I donīt think that the flyback is damaged. The monitor apears to be shortly used.

Any help is welcome.

Thanks

Rodolfo

Did you ever get you monitor working? I came across the same monitor, two actually. One is a little blurry, fuzzy, makes my eyes strain and the other seems to be dead. I thought it might be a power supply or something. My idea was that maybe I could make a good one between the two. What do you think?
