TV Input Changes by Itself

[pkreiker]

With no apparent system changes, my Panasonic. when first powered on, has started changing inputs on its own. It changes with no human interaction from Roku 3 to Soundtouch 300. I set it back to Roku, it switches back to Soundtouch. This persists about 30 seconds after turning on TV and Soundbar. The units are connected vial HDMI ARC cable

Thoughts?

Try turning CEC off in the TV menu.
CEC is supposed to make using your set up easier to use by automatically switching when sources are turned on. Doesn't work well most of the time.

I've turn the air link off.

l now I have to use the TV button, press Source Power, then Power buttons to turn everything on or off.

This is less frustrating, and easier, than reselecting the TV input multiple times.

turned off the Viera Link on my TV.

I now turn on/off my system by hitting TV, Source Power, then Power, then Aux, on my Panasonic remote.

This is much easier, and far less intellectually challenging, then hitting Power, TV, TV Input, selecting Roku an indefinite number of times, then Exit, Aux. My final answer.l

What is a CEC? I don't see that in the menu anywhere. I'm having the same spurious inputs problem. Cycles thru channels and inputs, goes to black snow screen.

Some manufacturers use a different name for CEC.. I think Samsung calls it simplelink.
Goggle the make of TV plus CEC and you should be able to find that name.

My Samsung tv was switching input sources automatically and it was so annoying. I removed the back of the tv and cleaned the mother board. I wiped and blow dried it. Since I did that I haven't had any more issues with my tv. I was not going to spend $250 to fix it like the tv repair man quote.
