Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.

SOURCE: RED LIGHT BLINKS SEVEN TIMES
The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.
