After a day or so of problems everything started working fine for two weeks. I thought perhaps it was something in the RCN audio stream, because it never repeated, and I know RCN has been doing some upgrades. However it's not RCN.
Last evening the audio drop outs started again. Now it happens in video mode and DVD mode as well. Only thing that works all the time is AM/FM tuner. So I'm wondering what is different between tuner and rest of the 1070. Maybe it's because the tuner doesn't use the Dolby processing section, or uses a different amp area?? I'm an engineer but not electrical or electronic so am just scratching the ol' bald head here!
In any case, the click is the same click normally heard when turning the unit on. This morning I was troubleshooting and had TV on for 2-hours before it started. I heard the click, lost audio, changed channels, heard a click got audio for a few minutes, got the click, lost audio, etc. After that I could sometimes get the audio back by changing channels, but there was no consistent pattern and eventually I'd lose audio and not get it back. DVD was having the same problem and its audio comes to the 1070 via optical, so it's not an audio cable problem.
AM/FM always worked. I noticed if I had AM/FM on for a while, I could go back to TV and have audio for 5-7 minutes and then click, gone. I ran FM for three hours as well with no audio drop.
1070 has 2-inches of clearance all around with plenty of room for warm air to rise away from the unit. 1070 is cool to touch, except over the heat sinks or amps back right where it's warm. Behavior certainly seems heat or failing component related to me. House is always at 78 degrees, so it's not hot weather related (112 heat factor in Boston today). After no sound last evening, everything worked fine this morning for a while. Again sort of sounds like a component gets hot and the amplifier turns itself off.
I've got an email in for the Outlaws. Looks like my 1070 may need help.
