I've got a TM 5200 HD and a darkmotor attached on the dish. All was fine until a recent update (but that may be a coincidence too) and now only a few satellites will be located by the dish. It is firm on Astra 19 but won't move to HB 13 for instance, yet will track to an extreme east/west sat apparently without problem. Any ideas anyone? A physical line fault or a software issue maybe?
