Tonight, I took my Dreamcast apart to clean it. It was looking grimey due to my sister leaving it on her floor when she borrowed it like 2 years back and I had never gotten around to it. The open button was also stuck, so I figured before I played Sonic Adventure 1, I may as well get it wiped down.
I was very delicate taking the machine apart. The only part that needed to be cleaned was was mainly the top half, so nothing was needed around the innards. I wiped it down, got all the funk and gunk off of it and before I put it back on I used a damp q-tip to rip down some bits on the bottom that had gunk on them (like the controller parts on the inside, nothing near the back).
After drying it, I put the machine back together and went to start it. It wouldn't turn on. I [tornado fang]'d with it a bit, turning it on then off, then removing the top carefully again and turning it on to see if anything was off. It worked fine, powered up. Except now, it takes me to the date screen and after about 2 seconds, the screen goes black and nothing happens.
Despite my best efforts, could there be some sort of water damage or if water did get inside, will it dry out and hopefully be fine? If not, whats causing it?
