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.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset.

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!
