Check the horizontal output transistor as there's a good chance it's shorted. If it's shorted, there are two common causes. The first cause for a shorted HOT is loose connections on a small coil in the base circuit of the HOT. To properly fix, you'll need to remove the coil from the chassis and remove all glue from the coil and the PC board. Then, re-solder the coil to the board. The second cause for a shorted HOT would be a bad flyback; which, is very common on 32" and 36" versions. The only way you'll be able to check the flyback is to check it with a flyback ringer.
When the HOT shorts for whatever reason, an excessive load is placed on the power supply. The immediate result is a squealing power supply. If the AC cord is not unplugged quickly, the power supply will burn up.
I think MAT electronics sells a kit that contains all the parts that usually blow up when one of these power supplies fails.
The CTC203 and it's similar ATC113 were the last semi-decent RCA's. After that, they started using low end Chinese built guts that were very poor quality.
