Here's the only tip in WinsTips that applies to vertical AND audio. Great
program, everyone should have it!

Check -12v Supply Off Pin 7 Of Flyback. If It Measures +4vdc Or Something
Odd, Check For Open Pin 7 On Flyback

Subject: [TechAssist] CTC169 Int. vert and audio
1994 model RCA 32" console style TV. CTC169 chassis. Customer complains of
loss of vertical to about 4 inches and distorted audio when this happens.
Did the in house call, changed CR4118 and the caps in the primary of the
switch mode. Didn't actually see it act up in her house. Tapped the chassis
thoroughly and saw no bad solder but did a bunch anyway. Left her place, my
cell phone rings 10 minutes later, set NG.
Any ideas ? This thing is in a huge upright cabinet and weighs a ton. It
must somehow be tied to both the vertical and audio. That's why I suspected
power supply.
HELP ! I really don't want to have to bring this tank in to my shop !
