      Even help trying to determine which pins do what

      I do know that the 2 connectors that are together are 24V and ground to the inverters

      Thank you much

        See the diodes on the primary which look a little brown - check those.

          Tom,

          thank you. I will check those

          Could this make the Transformer squeal?

              What? You too hear a high pitched noise?

              Does your TV still work?
