I'm not getting any power and there is no stand by light - it went out after a lightening storm. I figured the power supply board is the first place to start, but I'm not sure how to test for standby. At the very top of the board it shows: STB:8V ON:13V (see 1st pic below), but where exactly do I take those readings? I've already pulled the power board out so when I take the readings is it OK to test it outside of the TV?
I'd also like to check the mainboard but I'm not sure where to start with that one.
