Hey guys,
Last week I posted here about this same monitor and I figured out the HOT went bad and all was well.
Now, yesterday I go to turn it on and it's dead again...WTF!!!
The HOT is still good and I followed the Randy Fromm flowchart and I was getting around 170VDC from the ceramic resistor at R503.
The Flowchart then sent me to the "small wire jumper J33 at the 130V trace"...which I can't seem to find . There are NO jumper wires at all on the back of this thing.
I then tried to measure the voltage at the "metal case" at Q352 and couldn't get any reading...although I coun't get any reading on my other working K4900 either so I'm clearly doing something wrong here.
Any help would be greatly appreciated.
Thanks, ERIC
