Hello. I have had my Dreamcast for about 5 months and I've only played it twice due to my limit of games. The first and second times I have turned them on it worked completely fine. I have not played it or turned it on since then. I recently got a new tv and I tried plugging it in and I was getting no signal. To make sure it wasn't the tv I plugged in my GameCube and it worked like normal. Any fixes or help?
