Hi,
My old tnc145 transformer burnt out and I replaced it with a good second hand from second unit, the controller lights up but does not power up the monitor, which I know works as I plugged into my other machine and it fired up.
I am looking for a circuit diagram to check the outputs to the monitor, I have checked most of the active components and replace some caps and diodes as I have a spare non functional power board.
Any Help?

Hugh
