When i go to turn the tv on the green light go on and then off. i did the coe test error code repeated 10 times

I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again

That is a typical problem in the power supply. It could be a switching regulator that has i think 7 pins, but it gets the power supply up and running with around 157VDC. If that is missing the set won't power up at all. Where are you located. I'm in Louisville Kentucky. Let me know if that works for you. Keep in mind there are quite a few fuses in there too. so check those. I think on that model there is 7 or 9 fuses to check. Talk to you soon. Jay
