Serious! If the TV is new, you may check your homeowners insurance for a replacement. The Power company can Verify the power fluctuation for you. When an appliance receives a Power Surge like that, the sensitive electronics are damaged or weakened.
For PROTECTION: Get a 1000Watt UPS and use it between the house power and the TV.

Try different cable, if you still get the problem after replacing cables, then you have a defective sygnal board (input board).

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).

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...
