Check and replace the shorted component/s in its horizontal output section circuit. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Lets try something ,turn the set on and put you forearm in the face of the picture tube if your hair stand to static it means you have high voltage and your set is missing possible the screen or filaments volts,if the hair in your arm does not stand your set is missing the high voltage and the problem is related to the flyback but it does not mean is bad ,it could have a loose conection in one of the legs or in the near area,next time it happens tap on the side of the set to see if it reacts if it does you know you have a loose conection.If you are familiar with tv service this will be a good place to start but if you are not too familiar be safe and call for assistance from a servicer.Let Us know if you need more information and how it goes.

There are shorted component/s on the main board of the TV. Check the horizontal output section for fault.

If this has a format or spicture size button the remote, adjust to format 2. If not , discribe the picture, if it is cut off top & bottom , you have a vertical problem, if it side to side,then you have a horizontal problem.

Above is your service manual link.
OK well what usually destroys them is incorrect voltage IN, or a capacitor or diode shorted on the output(s). This is a very common problem. However you MUST always repair the Cause as well as the Damage, you so far have only replaced a Damaged part, but have NOT found and fixed the reason why this all happens. One simply MUST start at the Power supply, ensure ALL voltages there are spot on, and work out from there as to finding the actual "Cause" of the Fault, and any damage caused by same.

Hi, well I applaud you for wanting to have a go and try to repair you set. But PLEASE, start in the right place, otherwise you will simply waste your time and money, You see, you MUST start, in the right place, The power supply, FIRST, as, if, that isn't right, nothing else can be. But you simply cannot do anything without a Service Manual. In this it has everything one needs to repair the set. OK if it is shutting down, after that amount of time, of working and then faulting, then it is most definitely a "Thermal" problem, the way we "Find" problems such as this is "Freeze Spray" you use this on each component that is suspected of being the "Culprit" and you will soon,find that errant component. Now, also not every fault is a Capacitor, I see many, many people that think, that Capacitors are always the "Culprit" and replace them, because someone else had done so and it worked, well that maybe sometimes true, but most Symptoms, can, and do have many, many different "Causes" & also, now while that may be true in a few cases, a faulty Electrolytic Cap, or even, ordinary, Cap goes faulty, this is only a SYMPTOM, something has damaged those caps causing them to "Fail". One MUST always find the root "Cause", otherwise if you just treat, the SYMPTOM, the "Cause" will just make the "Symptom" come back, in short order, as the prime cause still, hasn't been fixed., Now Capacitors hate AC ripple, or Over Voltage. Thats it. Oh.. and Heat, if these Capacitors, are too close to a Heat Source, then thats a prime cause of failure. Resistors, hardly ever go faulty,and if they do, it is generally obvious. However it doesn't hurt to check values with our Multimeter. Remember though resistors are made, with up to 20% tolerance from stated value, as such, are not too critical, unless in Timing circuits etc. Always check, the Values, of resistors, as with any other component, with the power OFF. Now Diodes especially "Zener Diode", are another thing to check, those and ordinary "Signal Diode" should always be suspect. next we have Transistors and IC's. The Transistors MUST ALL be checked to see if they have a good, "Junction" this is done, with our meter set to "Diode Test" and usually are about 0.6 to 0.7. With IC's you must check, voltage levels, or Logic Levels, going in and out, have a look at the circuit diagram, and it will tell you what they should be. It is a good idea to always measure the Power Supply voltages, see if a "Rail" is Low, that will be because some component has gone somewhat or all short circuit, to Earth, now, if the "Rail" is Higher, suspect an "Open Circuit" component, like a Diode, or Transistor. The voltages expressed in the manual are spot on, ANY variation MUST be investigated. I have been doing all this for over 30 years now, and I do indeed wish, we could have a set of "Symptoms" and be ables to say.. "Oh that;s the so-in-so and replace this" however unfortunately this although does happen, most "Symptoms" can have literally tens, of "Causes" all often "Interlinked" One simply has to do a methodical troubleshooting procedure, and always think, "are my Voltages Correct" as this is how, you Fix the problem, by making them so. Keep up the good work. If that link above doesn't furnish a Service manual, it is imperative you get one, even if you must pay for it. It will pay for itself in about 2 mins.

there is a leak of high voltage in your tv so you need to opoen the back cover check for the source of the leak..if the leaks comes from the plyback transformer you can use sealant to cure the leak.

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

We have the same trouble! It is the power transformer. These models had faulty ones. Can you believe that this is the 2nd time we have had this problem? And our Beautiful RCA XBOX Entertainment Series TV's that is only 6 years old and there cousins all have these problems!!!! Our repairman (and good friend) told us that it would cost about $250 to fix. Of course he didn't recommend us doing this because the TV TUBES in these series are also very weak. He says that these Large Screen RCA TV's do not make it much past 5 to 7 years. So if you spend the money to have it fixed you will most likely be wasting your time and your money! Sure it will work for another year, but that is about all!
It is far better do what we are doing and go out and buy a new TV. Our Repairman Friend spend a lot of time researching new Flat Screen TV's for good quality and longevity. He states that we all should look at buying a good solid brand like Panasonic if you are going with a 32 inch TV or smaller. A Sharp if you are going larger then 32 inch. Far Better Quality on these TV's and a lot longer life! He states that the other cheap ones that we see out there today already are having a lot of problems! You get what you pay for!
These cheaper so-called bargains will have lots more problems in the months ahead and most will more then likely stop working all together in 2 to 4 years. So buyers beware of these great TV prices on these cheaper models! PLEASE do your homework and please listen to us and our repairman and you will not end up screwed like we were! Now we are stuck with an old RCA clunker which warranty expired after the first fix which was not done correctly! They came out and put a little solder and adjusted the Transformer instead of replacing. It was just enough to last another 6 months for the warranty to expire! Shame on you RCA! We then went out and bought one of these cheaper models and found that the quality is terrible! It already has problems and we are fighting to get them to honor the Warranty! Did I mention buyer beware? Something that looks and sounds too good to be true usually always is! Sorry for the long response! I just hope thise helps others!

Hi,

Before you Proceed, Disconnect the Power Supply, Unplug the Cord and then try to plug in after few minutes, say 30 minutes. If the Problem persists, more likely it's a Faulty Power Supply Board.

You need to have some electronic Experience to Open the TV and then you need to locate the Board. Once you find the Board, you need to pull the wires and try to Look for Swelled / Bulged / Leaked Capacitor. You need to go to Radio Shack or Order Online and then replace that. Once replaced, that would fix the issue. Usually, Bad Caps do have Ammonia kind of odor.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi
The squealing sound that you hear most likely comes from the power supply.
And it is most often caused by a shorted horizontal output transistor.
But that would have to be determined by opening the set and testing it. It is a common problem in rca`s and other sets, it is often caused by a bad flyback(high voltage transformer) and/or associated circuitry.
Hope this help to clarify things a bit.
P.S please do not rate this answer(unless it helps)as it is only a suggestion/information.
