Does any one know where I can buy a mainboard for my Dreamcast (new or second hand)? I have been using my Dreamcast via the RF modulator since it was new more than two years ago. Today I bought an RGB cable as I wanted to use the Dreamcast via my video projector (getting Shenmue 2 for Christmas, RF wont cut it at 7 feet wide). I plugged in the RGB cable hooked it up to my TV and got a rather greenish picture. I hooked it up to my projector with the same result. Because the projector is CRT I could see that nothing was coming out of the blue tube. I therefore suspected a faulty cable. I disconnected everything and replaced the old RF cable. Guess what no signal ! I then switched everything off again and reconnected the rgb cable. now I only have audio and no video. Further experimentation showed that I had a black screen which was displaying dreamcast graphics very feintly in black. I suspect this cable has fried the video chip. I will take the cable back to the shop tomorrow where with a bit of luck it will fry one of their Dreamcasts. If it does not it looks like I am stuffed and left with a duff Dreamcast. Is it possible that my video chip was about to go anyway ? Has anyone else had this problem ?
