My ZGEMMA H7S STB running OpenATV stopped receiving via its DVB-S2 tuners about a month ago. The DVB-T2 tuner continues to work.
Does anyone know whether I can confirm that the DVB-S2 tuners have broken, rather than being misconfigured? I have spent a lot of time with various configuration options but cannot complete a frequency scan.
Is it possible to replace the tuners?
