Aerosoft Australia 747MCP problem

Hi guys - thought I'd give it a shot here...

I Own the good old 747MCP by the Australian Aerosoft - which is discontinued. It's been a few years back, but if I remember right, the power supply malfunctioned and I ended up with no lights working - not the leds and neither the 7seg displays.

Any idea if this is repairable and how?

Cheers and any help is appreciated!

Ilan
