H/K 151AVR - ARC connection keeps switching TV source on power on.


Novice Member
Hey everyone,

I have a H/K AVR 151, which i use with a Samsun UA65NU7100. they're connected via the ARC HDMI slots on both devices.

For about 6 months the devices worked together perfectly. I turn the TV on, the AVR turns on, i turn the TV off, the AVR turns off. no problems.

Recently i've had a new problem pop up, as far as i'm aware i haven't changed anything to cause it to start happening. The devices still talk to each other and send audio as they should. However whenever I turn my TV on, after it turns itself on and sends a message to the AVR to also turn on the TV seems to switch its input to the AVRs HDMI slot once the AVR finishes turning on. This means i now need to adjust the source every time i turn the TV on before using it. Beyond this every few weeks the AVR stops reading signal from the TV and i have to turn the HDMI link off and back on again in the AVRS settings to get them back in sync

Any ideas what could be causing this or how i could resolve it?
