H.V OK, video information all the way to the CRT drivers. Screen voltages OK. I have a block diagram for this chassis only. If I turn up the screen control on the flyback still get no luminance on the CRT. The sound comes in slowly, about 30 seconds after start up. I checked all resistors on the CRT board OK .(posted for another chassis). I think this set if very similar to the TX82 and TX825. Can any one upload a schematic on this one. help appreciated, Bruce.
