Hi,

Got this monitor for free so I figured it was worth a try. Reported to have just stopped working.

The good:

CRT Heater on, HV crackle at startup, Power LED green.

The bad:

No raster.

Anyone got a schematic or repair information available?

Thanks,

Kirk S.

KDS AV-195TF No Raster - repaired

Originally thought there was high voltage. That was the degauss coil charging up. No B+ on the flyback. Flyback derives voltage separate from the HOT so I followed it back to the SMPS. Found open 0.22 OHM 1/2 Watt resistor (FR901). Replaced with NTE equivalent and the monitor works.

Resistor wasn't burned up or discolored. Simply open.

Hope this helps someone else,

Kirk S.
