You need to get yourself a wrench or pliers to loosen those cables! :righton: Even if D* agrees it’s a defective receiver, it’s likely they’ll ship you a replacement and you’ll need to unhook this one for the swap. I’d definitely try to see if it’s specific to a tuner or sat feed. It could be a bad BBC. It could even be a bad LNB or multiswitch or a bad cable connection. Without being able to unhook the sat feeds, you’ll never be able to test it. Of course if you have the PP, just call for a service visit to have it checked out.
