TV shutting off - electrical problem?

I've had a RCA model F26667 tv for about 3 years. It worked fine until a couple of days ago when it atarted shutting itself off and making a loud cracking noise while doing so. It now shuts off immediately when turning it on. Is this something that is repairable? Maybe needs a new power supply of something easily identifiable?
Thanks, Bill

That sound is a high voltage issue. It may be nothing more than dust inside. You might want to try this. Turn it off for half an hour, then un plug it for 24 hours. This is to try to eliminate as much of the HV that is in there. There is a good chance that things are not working as they should. Now take off the back and use some compressed air to blow out as much dust as possible. It's a good idea to do this outside. Don't touch anything while you do this. Some of the stuff can be nasty and you are much more likely to damage something, or yourself, than you are to fix something when you don't know what you are doing.
Maybe, if you are very lucky, it will be back in service.
BTW you say three years. Many sets have a three year warrantee. If yours is still under warrantee, don't do the above, just let them fix it.
Frankly if those ideas don't fix it, I would change this problem to an opportunity to get a new plasma TV. They are great.
TV's today are repairable, but most of the time the cost to do so is just not worth it. They are not really designed to be repaired so labor is high and the cost of assemblies (you can't buy just a part) are also high.

I will tell you straight off; I know nothing about TVs.
However I have had a 16 year old Sony 19" and a 5 year Quasar 27" repaired in the last two years. Both now work fine. The Sony had a power problem: would not turn on but all it took was to replace some kind of resistor. The Quasar could not keep a vertical hold and it was some form of regulator that needed to be replaced. Both easy fixes if you know what you are doing (I don't).
Find a neighbourhood Mum and Pop TV repair shop who are also known to be honest and take it to them. You would be surprised at how little it might cost. It may be something as simple as a voltage regulator which might be a simple and fairly inexpensive repair. My two TVs were less than 60 bucks apiece to repair, far less than the $300-500 it would have cost to replace them. If your TV is unrepairable they will usually take it off your hands with minimal cost to you.
Just my 2 cents!
