My HT-E4500 has been working perfectly up until the middle of last week. I turned it off on Tuesday evening, then when I turned it back on on Wednesday evening there was no sound. Not a sausage.
I went into the settings and turned on the test tone but there is absolutely nothing coming from any speaker. I have disconnected it all and re-connected it, but no change. I initialised to factory settings and tried, but still no change.
Everything else works. I can play discs and route the sound to the TV. Smart Hub still works (as well as expected anyway).
