SOURCE: TV shuts down
Remove the lamp assembly, There will be a screen on the top and bottom of the assy remove all dust from these screens. also check the tube at the top of of the lamp receptical this is an air cooling pathway. reassemble and fire it up. This worked for me and saved some serious coin judging from some of the other solutions I have seen (lamp and balast) ouch!!!

Please put back lamp (bulb) cover properly and check as lamp cover is open/ not fixed or improper fix is also cause of LED flashing.

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.
If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?
