1) TV OFF, leaving all the connectors in place.
2) Put the DC Volt meter probes on the two legs of the cap EC10.
3) Turn on the TV and look at the meter to see how high the Voltage jumps up to before it goes back down to 13V.
4) We also need the pictures of the whole back side of the TV showing all the boards and how they are connected together.
