Tv turned itself off. turn power back on, picture


Your TV is experiencing a convergence issue as indicated by the 3 blinks. The only way to fix this is replacing the convergence ICs. It is not a hard task to replace these ICs. You just need to know how to solder and work on printed circuit boards.

The convergence ICs are mounted on a large heat sink and are marked with codes starting with the letters STK and there are two of them. You need to replace both.

Look for the heat sink with two ICs mounted on it and check the markings.

Once found, cut the IC legs with a small side cutter and unscrew it from the heat sink. Remove the legs left soldered on the board.

Take note of the IC markings for ordering the right part and how it was installed. Don't forget to buy along with the IC a thermal compound.

Check the pico fuses on the same board. Most likely you will find a blown one. These fuses look very much like a resistor, not like the usual transparent fuse, and usually yellow.

Once you have the replacement ICs, put it on the board in the same way as it was installed before. Make sure the screw holes are aligned before soldering the legs into the board.

Put a reasonable amount of thermal grease/compound between the ICs and the heat sink and fix them with the screws.

Double check the board for any splash of solders that might cause a short circuit and damage the board.

Circuit board needs replaced


I replaced mine, it's called the Deflector board. Some people call it the flyback board after the flyback transformer that is located on it. I found one on Ebay for 25 bucks a while back, so good luck. Troll ebay or find someone that is giving their tv away on craigslist because the convergence or a bulb is bad. Don't base it just on your specific model of TV though because many of them share this common board.


Try part #271827. That was the part number of the board I won on Ebay.

Good Day, cs81801;
It sounds like the TV's Convergence Circuit has failed.First, try
to reset TV by unplugging TV from A/C source, for 2 to 5 minutes. Then plug TV back into outlet. Also, try the Magic Focus button on front of TV.
Still no work? To fix yourself call 1-800-458-6053 and ask for KIT 10. This will provide you with all the parts you will need. These are soldered in parts, or call an Authorized Service Center and have them give you a written estimate b4 repairs are performed. Cost? between $450 to 650 depending on your location and Service Center. Good Luck, big IRISH.

Spilled Water... where can I order new circuit boards?


Your Talking real expensive to replace the chassis in a projection. Was the Tv on when the water spilled? If it was only plugged in on standby it may be an easy fix. Do you have any soldering skills or troubleshooting experience?

Circuit board


You have to call RCA directy to find a parts rep for your area. Depending on the board, and the where the break is, sometimes a very skilled tech can repair the board. If there are surface mount components on the broken part of the board, then most likely it is not serviceable.

When calling for the price of the board, you will need to have the part numbers for the board, and the model and serial number of the set.

Sometimes, there are EPROM's involved with these boards. They have to be programmed and set up for the particular set, because of necessary calibrations. There are some adjustments that are unique to the particular set. For this, you will need to have this done by an RCA authorized service tech.
