Question about RCA F32650 32" TV
Hi have this problem with CRT tv model no: RC-4120PS, powersupply is whining.No high voltage ,no scr. voltage however the power LED comes on with the whining noise.There's also no voltage going to the Horizontal aswell as the vertical yoke.Have traced the whining noise to the high freq transformer not lopt.
The voltage going to the collector of the HOT is correct 135V but drops to 93V when I press the power switch, there's also otputs on two 25v, 470uF ecaps. of 10V each.
I have serviced a few tv's before
