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
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.

hey, first, have you tried both the hand remote and the on-set buttons? These sometimes stop functioning (broken buttons, worn out contact on the pad inside remote box).
Yes, assuming a reputable repair center is available (set isn't under warranty is it?).
If it is a high dollar quality set, then by all means take it in. Personally, I haven't worked on any flat panel TV sets, but the common failures above apply to various electronics.
A failure like you describe- perhaps something died in the standby circuit (a small portion of the circuit is always powered on to respond to power on command). Or, at the moment you went to power set on, something failed right at that moment.

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

Thanks dodgecharger,
It is strange b/c the TV was working perfectly, then all of a sudden wouldn't turn on. I am not good with electronics (i.e. changing the fuse), would you suggest that I bring the TV to my local television repair shop?
Thanks so much
I have a similar problem. The indicator light changes color, indicating the tv is on; but the screen doesn't light up. It will eventually, but sometimes it takes 15 - 30 minutes before it actually comes on. It seems to work faster when the room is warmer.
I have the same problem, but I see a red light flashing on the word lamp. I am thinking something needs to be replaced.
looking to fix asap
