I seem to be getting "tuner" problems where sometimes no tuner signal is found on any channel I select. It seems OK then suddenly starts to get the problem no matter which channel I select. At first I thought one of the three tuners was maybe faulty (three terrestrial only DVB-C/T2) because when it was recording using tuners A & C, selecting anything else tried to use tuner B and failed. However, I have disabled all the tuners and then enabled one at a time and they each seem to work.

Thinking it was the software (5.2.034) I went back to 5.2.030 - still the same problem. Is it likely to be the software and so should I go back to an even earlier version? Could it be hardware?

Thanks in advance for any suggestions.
