HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.
FUSE CHECK LIST--
3A 12v- fuse----(242208600623)
SM 3A 125v-fuse----(242208600657)
PART NUMBER FOR POWER SUPPLY BOARD
Please rate and god bless:)

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.
