another baumatic that no longer works

Hi.
Our Baumatic single oven is no longer working, sounds simillar to the post above re fan not working but not sure, can anyone advise if this is fixable:
1. Oven on convection mode stopped working, the top element would not work but everything else worked for 6 weeks.
2. Now, when it is turned on, nothing happens. If I turn it on then try the switch on the wall the internal light flashes briefly then powers down.
Is there any hope for my two year old oven?
thanks!
