The power supply fuse is blown and the 2.7k ohm resistor measures open. Does anyone have schematic for this unit? Power supply diodes don't measure shorted. Before I replace the resistor and fuse, is there anything else to check?
Thanks in advance, Charles
charles there are a few things to check before replacing the fuse & "2.7 ohm" resistor.140V b+ line has to be right & horizontal output has to be checked as well as regulator ic to make sure it's regulating at
140v.good luck
I don't have a schematic and I though the resistor was 2.7k ohms. Are you saying it is only 2.7 ohms?
Also, is the b+ marked on the board?
Do you know of a source for the replacement resistor?
Thanks for your help!
