My Goodmans GDB3 is showing signs of no power, looks like the there is input into the Pulse transformer 30031985 but no output, does anyone know where I can get one from, then I could use as spare or with bedroom analogue TV. Does anyone have a wiring diagram for Goodmans GDB3?

I have seen on a forum that dried-up capacitors might be the problem. I had one of these units in which the IC controlling the SMPS blew up, together with a couple of HV diodes, but replacing them did the trick.
