The power supply is going in to protect mode. Most often this is a power supply failure, or a failure on one of the circuit boards that is causing the power supply to go in to protect.
If the power supply fault is not too complicated an experienced tech may be able to service it without changing the compete circuit board.
The tech will service this by substituting boards to determine where the failure is occuring. Then he will change the board to fix the fault.

A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
