Probably a bad main board or T-CON board or both. If you're trying to fix yourself, try disconnecting the cable (LDVS) from the small board (T-CON) at top center of the LCD panel and see if it still cycles. Note, be very careful with that cable, it is very delicate. If it still is cycling off and on, then it is probably the main board. A slight chance it may be the power board also.

Your mainboard is damaged, the mainboard is the one where you plug all the cables (component HDMI), it is really easy to replace, you only need to take special care with the screws.
1. remove all screws in the back.
2. unplugg all cables from mainboard.
3. remove all srews from mainboard and replace it.
4. put all screws back and then plug all cables again.
5. double check all mainboard cables are properly secured.
6. Test TV.
7. put the back cover and secure it with the screws.
8. Enjoy your TV again.

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.
