Just over 3 years old. Normally when plugged in, there is a red LED on the bottom of the TV, and when it gets powered on it goes green. Now there is no light at all. When I plug the TV in or unplug it, it makes the "click" sound like it sounds like it's turning on or off, but nothing happens. What should I do? Is there any easy "checks"? I found the service manual online and it seems all the self-diagnosis is either on the screen or based on the blinking led, which doesn't get power. I think since the LED doesn't even get power, the problem lies within the power board. So it shouldn't be TOO hard to fix, if I can figure out exactly what needs to be replaced. What exactly can I do, should I just call Sony? I can open up the TV and check voltages, but I suspect they will all be 0 as I don't think it's getting power.
