Hi,
Red led blinks 4 times is an error code that shows that fan is not running in tv, check fans connections and make sure all are plugged properly.

Try recycling the power, Unplugg the power cord wait at least 2 mins ant then plug back in. Some times by turning it off an on rapidly will cause the microprocessor to lock up or freeze. Much like a computer does when you have to reboot it..

TV not working


Check the lamp door assembly, if the lights are alternating red then green, then this might mean that the metal pin that looks like a roofing nail is not making contact with the metal clip. Remove screws, reset panel in place and turn on, the red power button should be the only light on.
Good Luck!!!

Sounds like a power supply issue. Does the power indicator light up? Can you hear a click when the power button is pressed?
