Box type:5620
GUI enigmane2(enigma1/enigma2):
Firmware version:

Hi, I have a Dreambox 5620 which had the powersupply and tuner damaged. I have replaced both parts and the decoder is now powering up. Unfortunattly though the decoder won't get any signal, it shows a signal of around 70% and quality of 40-50% but the BER remains to mininum levels.
I have check the dish allignment and using an other decoder the image gets up but with dreambox no luck. Tried the latest firmware and channel list.

Any help to what I could do please?
