I appear to have a problem that quite a few of you have experienced. So, I followed all the advice but to no avail.
no sound but video out via hdmi. Solid lights after twice shutting down waiting and restarting. I have also tried different ports. Things like the obvious; type of outputs (tv) only to test all done. The tv is connected via lab also so get Netflix with audio in other words telly is working perfectly. We had a short power outage I think and since then just Visio.
please excuse the long winded explanation I just want to cover all bases and tell you I did that.
It would appear I need a tech with a replacement box according to some solutions.
