When did the problem occur?
Was it after a storm or power outage?
Did you purchase the set brand new from an Authorized Retailer?
Additionally, once the set shuts itself down, does the Standby light on the TV begin to blink?

Thank you
remove the power and hold the power button on the TV for 60 seconds, then release.
Then connect the power, turn on the TV and tell me please if it now functions.

The TV is now working Cool

What do you think caused the problem? Do you think it will return?

Expert:  Richard replied 2 years ago.
It was a build up of residue power, it can happen with any electronic device, it will be ok now.

The TV is back to not turning on. :(

Expert:  Richard replied 2 years ago.
Ok
It is the internal power board that's faulting then. We were able to get it to go for some time with the previous procedure, but it is at fault and needs to be replaced.
I am really sorry about this and you are going to have to return the TV to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
