Admiral TV GOJ12390 no video or audio. HV Okay but...
 

Any one have any tips for an Admiral TV with no video or audio? MODEL
NUMBER GOJ12390
The filaments are lit up, I have high voltage, screen voltage, and
when I turn up the screen control up I get a raster with retrace lines
across the screen, The picture tube checks Okay, but the video input
line to my output transistors is missing the composit signal.
Thanks, Dave

Thanks to my friend Les, after several hours of trouble shooting, this
television set is now fixed. What he found was that the 9 volt
regulator, IC601 was defective.
