When turned on, light changes from amber to white. No flicker on screen, no audible click, nothing. Only way to get the light to go back to amber is to unplug the unit.

All marked voltages from power supply appear to be normal. I've got 1.03V at A from the PS to the main and 0.01V at B. ON/OFF is 3.03V
I don't know what A or B should measure. From what I've read, it looks like U7 is bad, which from what I've also read, is pretty common with these units.
Right now, I'm kinda ticked off. I spent money on a part for another TV, just to see the same issues. I'd like to get this one going to get my mind off the other one.
