I recently bought a Sharp Twin FamiCom on ebay, the auction stated it was in working condition but it seems to be dead. The system only gets power on disk mode but there's no BIOS boot screens at all and if I switch the console back to cart mode and push the power button the power LED blinks for a split second and goes off. I opened it up and I can't seem to find anything wrong so far besides the usual dust. Any ideas/help will be much appreciated since I'm totally clueless at this point and almost everything I can find on the web is related to the belt issue which doesn't seem to be related at all with my current problem.
