The power supply is failing, or there is another circuit area that is pulling too much current, and the supply is going in to protect mode.
This would require proper troubleshooting by an experienced tech. If the problem is very involved, or the tech is not familiar with the set, he will require the service manuals and service information.

SOURCE: System will not power up
Remove the back from the set and look at the power board in the center of the TV. It will probably have one of more capacitors with the tops bulging out. Replace them with the same value part. Available from radio shack and almost any electronic suppliers.

6 blincks is protection code. Service tech needs to diagnose problem because failure could be from inverter board to panel itself.I'm sorry I can't do better than that.
