you have the problem in the heater try to resolder the parts in the crt socket the one that is connected in your picture tube if nothing happens check the resistor if open replace it common value is 5.6ohms.
Coil L14401 is not making a good ground. Remove him carefully, scrape the ends clean and the board where he was removed. Now reinsert and resolder this little guy,and Bingo you have your TV back. This is a common problem with your TV! Thanks for asking!
Coil L14401 needs removed and the ends scraped clean. Clean the board where the coil was removed and reinsert this coil and resolder. Your TV will be back as as good as new! This coil is located near the Horizontal Output transistor!
The TV does not have a reset button. If you have no picture and no sound, there is something wrong with the chassis. In this case the set should be serviced by someone experienced in the RCA CTC203 chassis. If you have no picture but do have sound, then it is possible that the 2 controls in the 2 little holes in the back of the set are not adjusted correctly. This is quite possible since you said you put a screwdriver in there and got a fuzzy picture. The control on the bottom is called "screen" and is the overall brightness of the picture and the control on top is called "focus" and is the sharpness of the picture.
