DL2 media problem

Hi to all community
I have a very big problem with a DL2. The media server breaks down. I try to change the power, but nothing. The motherboard does'nt want to start. Is there a solution ?
I'am sorry for my poor langage, but I'am a french boy, and please, speak slowly.

Well. Nobody want to answer me ? There is no more distributor in france, and I don't know what to do. May I change the motherboard, try anything ?
