Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check. 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. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Here is one source.

Bad capacitors it seems. Very easy fix.

Try to open the back cover of your tv but be sure to unplug it, then try to look for a bulge up capacitor beside the flyback transformer. if you see this capacitor try to replace it with the same value. feel free to send feed back good day and best regards.

Depending on how many hook ups you have on your tv it may have a factory designated channel. Example: Video 1, Game, etc. I know my TV has several different video channels. It's more a matter of trial and error until you find the vidoe channel for your oulet. Input channels are usually found before channel 1. Or look on your remote and see if it has a button to switch the channel to your input channel. Good Luck.

Make sure if you have a set top box (cable box) that the volume is turned up in that.

Hi iglidewell
In the last 7 years the price of plasma and lcd tvs has dropped quit a bit, so that makes it a popular choice.
But there are still die hard fan for the tube types, so you could ask from around $150 to $200 for it, or a quick sale at a 100 bucks.
Merry Christmas
P.S please do not rate this answer(unless it helps) since this is only a suggestion.

Unplug your tv for about fifteen minutes. Your tv receive a guide signal and sometimes when that happens it messes up your sound.

im guessing that you cant go to av mode because you dont have a remote, am I right? if thats the case you need to go to walmart and buy an RF converter. You can plug you dvd into the converter, then run a coax cable from the converter to your tv coax inout aka anteanna input, then depending on your converter switch your tv to either channel 3 or 4 and presto. it will hook up just like vcr's and onld nintendos use to. You can pick up an RF converter cheap at walmart or check e-bay, couple bucks and your watching dvds.

I had this happen. (ontop of the button board infront shorting out). I took the back off, and if your looking at the screen it'll be on your right. There is a metal box with two ribbons coming out of them, I unplugged both and plugged both in, and now she turns on without any issues. Not sure why, but it works. Now if I could get some help finding the circut board with the front buttons on it. I.e channel up down and volume.

Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.

The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

the switches in the front of the tv are usually the cause of this kind of problem. the fix is to replace all of the switches, because if 1 is bad the others are not far behind. each switch from rca is $5 to $10 each. good luck.

Try resoldering where the tuner mounts. Rca has had some problems with solder connections

Yes it is the Horizontal Output and a few capacitors and resistor that needs changing. If you are good at desoldering and soldering you could do this. I think on this set its the Q4401, caps C4402, Cr 4402, Check Q4802, C4102, If you just want to try new parts and hope it works then you have to check voltages at different points to fix set. Now it also could be Bad Flyback in this set too. I have seen where you change flyback and horizontal output and c4402 would do it. R4118, R4114

The pincushion is something that happens to this particular set. You may have the blue box type Capacitor in this set if not then a more brown or redish orange cap. I believe it is C4401. Most of the time its behind the Horizontal output. The cap gets leaky, most of the time it's a .47uf @250v. Try this, hope this helps

Need a new Flyback installed or there is a whole in it. If you are handy turn off the lights and look at it with the lights off. see where the hole is and fill it with plastic epoxy.
