Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.

Sorry to say but it sounds like your power supply is bad, although it is possible it is some other components in the TV because turning it off allows all diodes etc to power down completely. Unfortunately after a bit it happens again which leads me to believe again power trouble.
