This is another one of those questions that has probably been asked and answered several times, but my feeble search skills haven't found any of them.

I have a Denon AVR-1612 hooked up to a Sony KDL-32LL150 via HDMI. I figured out how to get the receiver to turn on when I turn the TV on, and turn off when I turn the TV off. Life was good. But soon (within hours) the two units starting turning themselves off at unpredictable intervals. The intervals are measured in hours rather than days or minutes. When this happens, they both shut down at once. Prior to be introduced to the new receiver, neither the TV nor any other electrical stuff in the room had ever done this before.

Any clues about what to look for would be appreciated.

I forgot to mention that I have already double-checked the sleep timer settings on both components.

When the shutdown happens it any other electrical equipment in the house starting such as the refrigerator or and air conditioneer?
Are both units on the same power circuit?
Are you using a surge protector?

Sounds like your "HDMI Control" settings are ON and one unit has an "inactivity" timeout feature. Until you figure out where the off-command is coming from, check the TV's HDMI Settings menu and turn them all OFF?

Turn off the CEC HDMI control functions on both the TV and Denon. Manually turn on the TV and AVR.

wajo's suggestion is exactly on target. Thanks! Although I had checked the sleep timer feature on both units, I had not checked a Sony TV feature called "Idle TV Standby". Turned that off and life is good again.
