Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Anytime you replace the Ymain, it's recommended that you replace both Y upper and lower buffer boards also. Most likely you've damaged the Y again, so I would re-order all 3. In thte future unplug the P/S plug to the Y section and leave it discharge for about an hour before plugging it back in.

Vertical line picture


problem is caused by the loss of horizontal deflection signal. It is quite surprising that the entire unit is still working, since usually, a loss of H-Out will disable the entire set. Problem can be as simple as loose solder connection to a more complicated defective horizontal circuit. I would suggest havint it checked by a professional TV tech.

Hi there

Try replacing the electrolytic capacitors in the power supply section. I started with replacing (2) 860uf 180v caps just after the bridge rectifier and continued along the circuit. Some (15) or so capacitors later,it finally cleared the the horizontal bars and lines and the high pitched noise. It also fixed another intermediate problem of no video, when turning on the power.

Here is a picture of what they look like:
