Yesterday my LCD TV would not turn on. The TV was working fine, I turned it off, came back an hour later and when I hit Power nothing happens. I moved to 3 different outlets in my house and nothing. No lights, nothing, it just seems dead. Please help

Re: LCD TV WONT POWER ON
A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.
First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.
If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.
I just had good news in fixing my Vizio L6 that suddenly completely died. I have a little electronic experience. I pulled the back off, and removed the cover to the main board and power supply. The fuse checked out okay, but no DC power was being sent to the main circuit board. I removed the power supply circuit board, and checking the bottom, i found a bad solder joint. Soldered that up, and now the set is running fine. Best case scenerio. Good luck Nick

poke it open, you'll find bloated capacitors at power supply board. biggest one, with power cord pluged into. replace with thesame value(s).
you good to go!
don't lie, next time! your set has been acting up fpr a while, before it quit. Remembering: few attempts to turn it on, then it works!
