Re: Won't turn on - comes on and goes right back off
Is the picture good or is it dull and dark?
A dull aka weak picture tube will cause low beam current and blank the screen. Last set I had do this I turned up the screen control to make it brighter. Use caution and don't turn it up too high were you see vertical retrace lines in the picture.

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.
IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
