The TV has a strange powering off issue. It seems the longer the TV is unplugged, then when you plug it back it, the TV will work. I can only get about 4hours of use before the tv turns it self off. And to get 4 hours I have to have it unplugged for a couple of days. If it is plugged in and I attempt to use it every day then it will last 5mins to an hour before shutting off. Is there an easy fix to this problem? I have tried using fans to blow on the back of the tv, thinking it may be an over heating issue, but this has not effect. What are my options besides drop kicking it into the nearest land fill?
Too bad I didn't see this post earlier...it's probably OBE by now. Still, your problem is most likely a bad capacitor in the power supply. If you know your way around a circuit board, you can probably find the bad cap via visual inspection (bulging top, leaking electrolyte, etc.), and can replace it yourself.
NOTE: TVs have numerous high-voltage circuits, and large capacitors can retain dangerous charges for a long time after the electrical source is disconnected. DO NOT work on your TV unless you have the knowledge and skills to do so safely!! Otherwise, take it to a TV repair shop--this is a trivial repair for them, and it probably won't be too expensive.

Surge associated with power outage can make disasters in refrigerators. You need a power protector for refrigerators.
Now, what already is damaged, should be repaired by an authorized techician.
For protector, you can do a search; typical return is this one
if you want to eliminate magnetism, you have to degauss the screen, if you don't know how to do that, here is a small guide for that: http://www.wikihow.com/Degauss-a-Computer-Monitor
but that strange shutting down its the transistor... so your best choice is to send it to a repairman to change the transistor.. if you try to do that for your self, you could even get shocked with the electricity contained in the tv... even if its turned off and unplugged..
I know this is going to sound strange but I have something to check. If you have LED lights in your house turn them all off. When they are off turn on your TV and see if your TV stays on. Yes, there could be many problems but this one is cropping up quite a bit. If this does not work then you need to take a look at the power supply board.
Had a very similar problem with mine - not sure if this will help or not, but it seems to be doing the trick (channels scanning as I type). I unplugged the tv for about an hour. I unplugged the cable, and all the components. Then I turned the tv on, and was able to get to the menu screen. Previously, I couldn't change channels or even power off from the buttons on the side of the unit either... Once there, I plugged the coaxial cable directly into the side of the set, then ran the auto-scan. I know it's not a techincal answer, and a bit strange, but as I mentioned, it seems to be working for my issue.
I don't know if I solved the problem. I find though if I turn the TV off and unplug it and then plug back in when I want to watch it - it works. I don't know why but it does. My remote still does not connect to the LCD but I have cable HDTV so chanel changes work from that control.
I am pretty ********** that it is only a year old and this has happened but what can you do? We live in a disposable world.
I was trying to get to your Premium assistance Plan from where I wrote my issue but I don't know where to pay or what to do on your site it keeps taking me all over.
PEOPLE, YOU NEED TO GO BACK TO THE STORE, BUY THE SAME TV AGAIN, SWAP THE TV'S AT HOME AND RETURN THE "OLD" TV IN THE "NEW" BOX WITH THE NEW RECEIPT. IN THE CASE OF TOO MANY RETURNS, HAVE A FRIEND, MOM, DAD, SISTER, GIRLFRIEND TO BUY ONE FOR YOU AND DO THE SWAP LATER.
NOTE: I REALLY HATE DOING THIS TO THE STORES, BUT IF YOU PAY FOR SOMETHING IT SHOULD LAST LONGER THAN 30-40 DAYS. PROBLEM SOLVED! :)
