Here are things to check.

1. possiable bad power supply or a bad componet on th power supple "capacitors" or what have you.

Now if your good at repairing monitors you can pop this bad boy open and check for any swollen capacitors you will need some soldering skill.

2. Replace power suppply

Ether way here this will need repair, I am not there locally looking at the set so I am going by what you tell me and the most common issues with these sets. When in doubt here bring it to a local shop.
