Low Voltage B+ Hantarex mtc9110
« on: August 05, 2024, 06:23:25 am »
I am trying to repair hantarex mtc9110, the diodes and resistor were damaged. I replaced the damaged elements and BU508A. After turning on the monitor the lamp does not light up and I have too low voltage on B+ - 112V.  Please advise where I can look for the cause.
instead of resistor r80 I have installed variable resistor, it looks like something leaked from it, it can't be turned, does anyone know what value it should be set to (currently it is ~19k)

I am attaching photos in the attachment
