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).

This also happened to me and may continue to get worse... If it goes away for a while after warming up, then it is the same problem... The LCD panel is probably going out, when that happens the cost to repair it is more than the tv is worth... If it is in warranty then you can have it replaced or fixed.
