Question LG 43UH603V TV and Pioneer VSX-828-K Receiver HDMI ARC - No Signal


Well-known Member
My new LG 43UH603V TV arrived today and I cannot get the HDMI 3 port to work with my Pioneer Receiver VSX-828-K AV Receiver.

HDMI 3 is the only one that supports ARC. The TV just reports "Inactive port" despite the Receiver outputting my Humax Youview box.

- It works fine using HDMI 2 (which doesn't support ARC)
- HDMI 3 works fine if I plug the Humax Youview box into it directly.

The LG 43UH603V TV is set to:
Audio Out (Optical/HDMI ARC) - This disables the internal speakers

The Pioneer Receiver VSX-828-K is set to:
HDMI Setup:
Control - On
ARC - On
Standby Through - Off

As far as I can tell there's some ARC conflict that's oddly meaning I cannot even get a picture. I've tried turning off ARC on the TV and Receiver but still "Inactive port" :-/

I'm thinking the LG TV ARC and Pioneer Receiver ARC aren't compatible with each other and I'll need to run an Optical cable to the receiver but would like to confirm this.
