SOURCE: Tv cuts off and green light flashes
If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.
Good luck!

SOURCE: tv immediately turns off
Four flashes indicates a problem with the backlight on the TV. It can be caused by the backlight inverter board (the power supply for the backlight) or by defective backlights in the panel It is USUALLY the backlight inverter board that is bad, but I have seen both components fail at various times. This set is fairly new and should still be withing the one year warranty, so you should contact Sony at 800-222-SONY to get it repaired. Be sure to rate this solution. Thanks!
