I have already posted about the loss of one of my tuners. To recap I have fixed dish on tuner B running 28E and a moving dish on tuner A. Tuner B no longer works but tuner A is still working with the motorised dish. What I have been trying to establish is it the fixed dish that is faulty or is it the tuner, so I connected the cable from tuner B onto the satellite input of my TV which has both normal and satellite tuners and it worked, so my fixed dish is clearly OK, but this is the strange thing, without the fixed dish installed on B in my Duo2 the tuner A no longer worked. So it appears both cables need to be in inserted in the duo for just tuner A to function. I have accepted that my best option is to just to purchase a new box, but would be interested to know if anyone else has experienced this issue and was there a fix?
