I've got no activity from the tv at all. I opened it up and I hear a faint, high pitched squeal, alternating with a click sound. Squeal, click, squeal, click........ Coming from the power board. This happens as soon as the power cord is plugged in. Pushing the power button has no effect on the noise. Weirdly, when I unplug the harness that runs from the power board to the main board the noise stops.
I checked for voltages at the plug on the power board where the main board would plug in. I get 5v, but no 12v or 24v.
What do you think?
Thanks.
