Burnt cirquit board on 3200MP

I have a 3200MP that one day made a loud popping noise and gave off a bright light when I plugged it in to the wall socket. I asumed that it was the bulb so I got myself a new one but it didn't help. I opened the projector up and disassembled it and on the bottom cirquit board I found a busted fuse. I replaced the fuse but only to have it busted once again imediately as I attached the power cord. Took it apart once more and found that the cirquitboard with the fuse (the one where the power enters) is burnt in the "back" where there are four rectangular black "thingies" with three respectively two legs sitting in a row (3-2-3-2). Sorry for the poor quality of information as to what these "thingies" are but I'm not that good on electronics ;-)

 

Does anyone know what has happened and/or know if it's possible to replace this cirquitboard with a new one and if so, where do I get a hold of one and what's the approx. cost of it? I live in Stockholm Sweden BTW.

 

Thanks.
