Freezes at bios screen

I have a sega cd model 1 (bios 1.10). The sega cd will turn on, but freezes at the bios screen. The lights on it never flash or turn on. However if you leave it for 5 secs then disconnect the power form the sega cd unit, the genesis will start playing music but nothing else happens. I already tried cleaning the connection contacts on both the genesis and the sega cd. Can anyone help?

Answer this question I have this problem too

Is this a good question?

Then check all ribbon cables for shorts

And finally got it running
