Note: I've worked with high voltage circuits before.
I have a very nice looking 1989? RCA G26231 TN Analog TV. I just know this thing would rock for classic gaming. The only problem is that it has some bad image warping using the composite RCA jack (see below). I took the TV apart and looked it over. It was very dusty but also had some hot candle wax spilled inside it. I cleaned out what I could, but it looks like I'll have to take out the main board for a good cleaning. All the components are thru hole, so that's a plus.
If someone could give me their guess to what to look for or what part of the main board circuit is the likely culprit, I would be grateful. It might save me some troubleshooting time.
Edit: This is a CTC156/156
