Hello. I lost the audio on my Humax 9200T a few weeks ago. The TV was fine. When I turned on the PVR, the video was OK, and I could change channels using the PVR handset. But there was no audio. It was not muted. I could play recorded programs but again, no audio. So I did a manual retune and all was well. For a few days.
Then I found that I couldn't turn the 9200T on - at least, not what would show on the TV. So I gave it another try the next day, and it would turn on, except that it appeared to have lost all the tuned channels! So I did an automatic retune, and all is now ok, including audio. But I have very poor video. Trouble is, Humax seem to be reluctant to offer any advice. They have completely ignored at least 3 requests for help on uksupport@humax-digital.co.uk. The dustbin beckons!
