Hi mimisiku,

Thanks for the advice. I power down the box and on the screen after "DREAM" in colour letters, “Boot #84” appears.

Recently I bought a used DB800 HD se. Everything is fine except that I have a problem with option when I want to (used the button “<” on the remote) switch to the previous channel in history. The device indicates problem and reboot its self.

Can someone tell me how to fix this?

Thanks.
