Hi at all, I bought an old computer with the wishing to make it alive. It?s name is Kaypro-II and it has a 9" green phosphor monochrome monitor composed of a LR30477 E39164 TOSHIBA CRT and a printed circuit steering Toshiba TLC-134-TV-0. I tried to supply it with 12Vdc and I noticed that the cathode of the CRT is lit, while the screen does not turns on and no shows light even using the knob back adjustment for the light intensity. Wishing to do TV repair technician I need the wiring diagram of the circuit electric drive Toshiba TLC-134-T-V-0. Is there someone who has it? I seem to hear at the power on from the CRT an high-frequency hiss and i tryed to see if come out a shoke from the flayback transformer but nothing come out.
