My Dreamcast displays no video!

When I turn on the Dreamcast it has audio but no video. I have checked and it is not internal. I just had it cleaned and it was working after that but it just stopped working overnight. Please give me an on-site solution!

My friend has a sega dreamcast which turns on, shows the menu, but then turns off after only 10 seconds. I've seen reports of a dreamcast turning off during game play, but they all say it's 15-30...

Most likely it is over heating due to a fan that stop spinning or dust in the vents. Make sure the fan is still working and clean it out with compressed air.
Here is a great site all about repairing it -

My dreamcast will power on for a moment that shuts off.


Sounds like your dreamcast is getting cut of from its power, the dreamcast sometimes gets a build of of dirt around the power connector pins that supplies the entire unit with power, try this youtube guide here for cleaning you don't need to do the bending section of the pins. just clean them and the actually plastic socket section where the pins go in.

Audio but no picture

Try using another RF cable. If that doesn't work then open up the system, and clean it out. Make sure there's no dust or anything that shouldn't be in there.
