Question about RCA F19240GY 19" TV
Hello, The picture in my RCA TV is getting scrambled time to time in random parts of the screen. It looks like some portion of the screen is getting horizontal deflection to the right. It appears randomly in different places. Hitting the TV helps to resolve the problem and it may work Ok for 1 minute or for 1 hour then it gets scrambled again. Also periodical thin white diagonal strips appear and disappear with random spacing. Thank you.

Get an ESR meter and check all the electrolytic capacitors in the set! I am sure you will find many decoupler and coupling capacitors that are on the edge or too high in ESR.

I have this problem as well-have to keep the house cold enough to keep it on. I also have a box fan blowing into the right side vents (the side OPPOSITE the built-in dvd player). It helps a lot to have the fan there, but if you put the fan on the left side vents you will have much more frequent shut downs.

It could possibly be a protection circuit in your tv that protects it if something is not functioning properly. from what is described, it could be anything from overheating to even a bad power supply! I would have someone look at it. Good Luck!

this symptons is caused by a breakdown in the vertical deflection circuit. hence, the trouble may be in the vertical oscillator, amplifier or output circuit. in most modern tv the vertical ic is usually composed of these said circuit inside. the ic have many pins, standing on a heat sink and smaller in size. try to check also the capacitors surrounding it. sometimes leaky capacitor may cause this problem. good luck!
