I turn on the TV, the indicator light goes green, the backlight comes on, but no picture, after you turn it on that way, (using the "button" on the tv, the remote dosen't seem to do anything), you can only turn it off by switching the main switch on the back next to the power input. I tried what the tech support said about "letting it sit idle unplugged for 30 minutes or more, then turn on with remote only and hold power button for 8 - 10 seconds", which i think is a load of bullsh*t, i think it's just to get you off the phone.

Re: No Picture, Indicator Light Green
If your TV is a year old or more, chances are that the power supply is starting to fail on your TV, causing all kinds of erratic behavior up to the point of not turning on anymore.
I service these power supplies since it does not look like there are many service parts available anymore. The only way to get this TV functional again is to repair the power supply to the component level.

TV Repair Help for a TV With a Black No Image on the Screen ...I Have A Sanyo TV I Can Hear But Black Screen Im 14 And Dont Know What To Do ! .... power button the power light goes from red to green, the screen flashes on then goes black ....Troubleshooting LCD Backlight Failure Samsung LNT-4066 ...
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
That means back light inverter board could be bad or power supply board does not provide proper drive volts to back light inverter board so it is not working. Need to check both boards accordingly and replace defective board to get tv back in business. Let me know if you have additional question along with exact model number of your tv. Thanks.
If green light in front of TV blinks while picture goes off and comes back then its symptom of weak lamp that need to be replaced.
And if green light does not blink in above process then let me know.
