Hi. I have an RCA TruFlat tv (about 27") at my vacation home. I bought it about 3-4 years ago. It gets used rarely, but while there two weeks ago...it worked fine. I went back this weekend and it acts as if it is getting no power whatsoever. I checked the outlet. It's fine. I had it plugged into a surge-protector, so I dont think if got fried by an electrical storm. I really like the tv and want to have it repaired. Can anyone give me a clue as to what the problem can be...so I dont get burned by the repairman. That seems to happen a lot to me! The tv cost me about $400. Dont want to just toss it in the dumpster. Thanks for your time.

Hello Dino!
If you are familiar with electronics you can try and do the following:
Unplug TV and let sit for 10-15 mins
Remove casing
Inspect electric board for anything that looks like it's burnt.
Inspect any solder joints to make sure they are all good.
Some or most TV's will have a fuse inside. Try to locate this and inspect.
It also maybe the actual on/off button, but is unlikely.
Calling a repair man can be expensive. They will charge anywhere from $50-100 just to drive to your home.

Do not open the TV. That would be stupid and dangerous. Televisions have high voltage inside even when unplugged and turned off. You could easily kill yourself by touching the wrong location.

racraft,
that is why you let the tv sit unplugged for a bit. Most TV's will lose the energy within a few minutes if not seconds.

And if it doesn't lose all the charge after a bit?? He gets zapped, and possibly killed.
It would be like playing Russian roulette.
DO NOT open a TV unless you are trained!!
Theoretically, capacitors could actually hold a charge forever. Highly unlikely, but possible.
The charge will eventually leak off, but it depends on things like the humidity of the air, the distance from the charged end of the capacitor to the nearest
ground point, insulation, etc. There is no set amount of time to wait. Some people say wait a few minutes, some say wait a few days. No one is right. You need to test the capacitor for a charge and discharge it if there is one.
