What happens exactly? I had a dreamcast that worked fine for ages, then one day it started to stop working. It would sometimes play a disc for a minute or two, and then just cut out, as if the signal to the TV had gone or something. Sometimes it would cut out straight after the dreamcast logo movie, and sometimes it'd not even get that far. I had to get a new dreamcast in the end, but it was years later till I bothered coz I had an xbox by then and didn't play my dreamcast much. Last year though I missed my old dreamcast games so I bought a replacement off ebay.
