I'm not familiar with Normende sets. Around here they did have a reputation of being difficult to repair, but I don't know if this reputation was deserved. It may simply have been because the local service guys were not familar with them.
Assuming the set is completely dead (the standby LED does not light) I'd start looking on the primary side of the power supply. If the fuse is intact it may be something as simple as dried out capacitors. If the fuse has blown severely (blackened glass) you have a dead short somewhere. Check the rectifier diodes and chopper transistor. If anything has failed spectacularly (blown apart) the set may have been a victim of a power surge. If so you'll probably need to replace the controller IC, optocoupler and other semis on the primary side of the power supply. You may also find further damage on the secondary side.
It's hard to be specific without seeing the set.
You're location is listed as Melbourne. If that's Melbourne, Australia I am in Dandenong if that's not too far for you. I'm curious enough about these less common sets that I'd give it a go if you're not in a hurry.
