I've tried connecting it from the wall to my panamax conditioner, unhooking all HDMI, removing the batteries from the remote (universal mx-850) all with no luck.
Anybody seen anything like this? I was going to try and call Nick today, but it got too late.
Could a cordless phone, wireless internet, etc cause interference like this. We dont have a home phone, and tried shutting down the wireless net.
Do a Save User Settings (so you can recover later). Then do a Restore Factory Defaults. Then power cycle the unit both at the front panel and with the back panel switch (to force a complete fresh start). If you have anything attached to the serial port, disconnect it while the unit is off.
Leave the unit powered on in Factory Defaults like this -- you probably won't have video but you'll be able to see what it is doing on the Front Panel.
Does it still make random changes? If so, use the Front Panel buttons to get to Setup > Trigger / IR / RS-232 > Set IR Inputs and clear the "*" from every single location in that matrix. Once you do this, you will have to continue via just the Front Panel as you have turned off all remote control IR access.
Does the unit still make random changes with all IR ports disabled and with no serial connection? If so that sounds like a hardware fault, but you can try re-loading the V1.33 firmware on top of itself to see if that clears it. This may be dangerous if the unit thinks it is receiving IR or Serial commands WHILE the firmware install is in progress. So it would probably be best to call Anthem tech support and have them work this with you.
If the Reload Factory Defaults or the turning off of the IR inputs makes the problem go away, then you can work your way back from that. Obviously you should make sure the original Anthem remotes are not in the room. Leaving the unit in Factory Defaults, try enabling just the Front IR input for just the Main Path and see if your remote seems to work normally with the unit (remembering that it is still in Factory Defaults). If so, Reload your Saved User Settings and go in and disable all but the Front IR input for the Main Path and try it that way for a while.
If the unit works properly in Factory Defaults, but not when loaded with your User Settings, then something may be corrupted in your User Settings. Try manually re-entering enough of your user settings to get video and to play a source and see if things still work.
Some display panels put out a lot of IR into the room. The usual result of that is that devices can't see the IR from your remote and so they don't respond -- rather than responding randomly. But it still wouldn't hurt to turn off your display and see if the problem goes away.
Radio devices like cordless phones, cell phones, and wireless internet can not affect the IR inputs. Even if the Anthem picked up radio frequency interference from the, the frequencies are so different it would not trigger IR style responses.
Normally I would suspect your programmable remote (bad programming or faulty remote), but you say you removed the batteries to disable that remote and the problem is still happening. I presume you are not using any OTHER IR remotes in the room besides that programmable remote, right?
