This is an error code of some fault inside. Kindly call in a qualified service technician.

Bad main logic board. Probably won't be able to find it. You can try Encompas Parts. Good Luck to you.

No the blinking lights are an error code with an issue and that protects the TV from further damage.

I believe that is a power supply board failure code. Time for repair! Sorry! Take it in for service or you may try to repair it yourself.

After I unplug and then plug tv to reset I get a solid standby light,then when I push the power button I get a green light that blinks 6 times then it blinks red 6 times and then red 6 times continuosly with a slight delay between the 6 blinks of red.

The red light blibking 6 times indicates that the power supply board has a defective or damaged area. I know this because i had the same problem...bought a damaged tv for parts and replaced the power supply board as the tv would not turn on...wokrs like a charm now.
