My System: Dreambox 7020 with 120 gig hard-drive disk - running a motorised dish DM800 +DM600 +DM500 although only usually the 7020 and 800 are both on.

There have been many cases where the 500's are shipped with faulty tuners.

And this is one of the side effects.

Talk to your DM Reseller (I'm guessing its a clone), also guessing that you have recently received the box and never had it working correctly.

But it could be the lnb, have you changed that?

You also need to check the output voltage to the lnb when switched to a horizontal channel

The lnb is ok, the voltage is the problem, on R710 the switching is correct, the voltage on pin 3 of U70 is 1.15v when on V and 0.87v when on H, not sure these are correct and the voltage on pin 1 U70 remains at 12.23V for V or H.
