My rca truflat 27f520t27'' tv keeps turning off and all

There is some shorted component/s on the main power supply regulator baord to your TV. Work with main power board circuit is fatal to any inexperienced person, as 80% of the components at this stage will be Hot [electrically], when the set is switched ON. Without switch it ON, you cant check the voltages at this section. S, if you are not experienced to do this work, contact any experienced service technician to get this set repaired.

Before trying anything else try resetting the TV to the factory specs.
To do this simply turn the TV on using the power button on the TV while holding the reset button on the remote. While you are still holding the reset button the TV should turn itself off then back on again.

This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations: What was the TV doing (it actions)prior to it going out? Did you hear any sounds before it went out like buzzing or crackling? What do you hear when you try to turn it on now, clicking? These questions are just to develop some background into what might be happening to your set. Thank you, Shuttle83

This is usually down to a safety feature cutting out the Television from harming itself. Or quite possibly a fault that make it turn itself off - it may well be thinking it's receiving the command to turn itself off. Either way, it's impossible to find out without opening it up. A professional repair is the only way, check up on your warranty. You may want to plug it into a different power source, just on the off-chance that it may solve your problem - but don't get your hopes up.
