    Grundig GUD300HD Set top box. No signal!

    Hi Folks.
    Have a brand new never used "Grundig GUD300HD" and keeps displaying a flashing "no signal" warning. When the aerial is unplugged it stops flashing but warning remains steady. Auto tune picks up and stores the stations but still says no signal and "no information" when channel is selected.
    Have scart, hd and antenna all connected. any ideas where to check would be appreciated.
    I get reception on other units.

        Have you tried updating the firmware over the RS232 port?
