Sony raster
Check from the service manual for the proper specs that is required for the
screen voltage. I think the voltage is checked with the brightness control at minimum in that set, but I cannot remember for sure. Going from memory, the typical G2 or screen voltage should be about 80 to 130 Volts, depending on the particular CRT and design. If you have an excessive G2 voltage and the CRT is not shorted out, the fault is most likely in the HV multiplier. In the Sony sets, this is usually a part of the flyback transformer assembly. -- JANA _____ "Vince" wrote in message ...
