no sound just the load up screen then it shuts off and after about 5 seconds it turns back on...over and over again.......I won the tv sometime last year so around 1 year old!

There are a couple of things that could cause this, unfortunately there is no reset for this television other than unplugging it. It will have an internal failure at this point. I will try to explain the possibilities the best I can.

First you could have a failure in the power supply, we have seen some capacitors fail in your model and cause funky problems like this. If this is the case you could be looking at somewhere around $175-$200 to fix the set.

Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set. The panel in your tv is about $800 just for the part.

Any of these could cause your problem, but it will require troubleshooting to determine the exact cause of your problem. If you have experience, and test equipment and would like to attempt some troubleshooting I will be happy to assist you, however if you do not have equipment or experience then you would need a repairman at this time to get an exact diagnosis. I am sorry that I don't have a quick fix or easy answer for you on this one, it is definitely an internal failure.

could hacking the usb to play movies have caused this?
Expert:  Tim Nolan replied 5 years ago.
When you say hacking what do you mean, what did you do exactly?

Did this happen right after you did this?

I programmed a universal remote to get access to the menu settings of the tv, then went to option 3 and changed divx to 1. It played the first movie I tried but not all of them, thought this could be due the audio so changed that too. The last movie I tried had picture but no sound. I didn't have the batteries in the tv remote to stop the movie so I just shut the tv off manually and that's when it started.

Ok but the tv has been working since you did this?

yes it did but only to the point where I changed the "audio amp" setting to something like "sas***" or something like that. But like you said, it was working until I shut it off manually. So are you saying this had nothing to do with it?
Expert:  Tim Nolan replied 5 years ago.
Yes I would say you had nothing to do with it, sounds like a failure on its own.
