2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If the issue is still unresolved after performing power reset, try to pull up the menu of the TV by pressing the Menu or Wega button on the supplied remote control or on the TV itself. If the menu does not appear, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

I've got the same problem. Powers on, after a minute or so it powers down while the green light flashes. I understand that its cooling itself down to power on again, but the reset is not correcting my problem. What is possibly malfunctioning to cause this continuous cycle? I have the ability to replace parts myself, but I can find anything g that tells me what to replace. It would seem that it is a faulty sensor, but I'm not willing to jumper anything as I'm not certain if the sensors are normally open or normally closed.
