Onkyo Tx-NR609 ARC problem with Panasonic UT50 plasma

Hi guys not sure where i should post this

but ive just got a new Panasonic ut50 plasma tv which supports ARC now ive connected my Onkyo amp and enabled the setting on both TV and amp and it was working great for a few hours then it stopped working (no sound as the amp takes over the TVs sound) so after a fiddle for some reason now when im watching the inbuilt freeview hd when I turn the amp on it makes the TV lose signal its very strange.

when you change channel on the remote for asplit second the picture comes on then goes off once the Chanel is selected on the amp.

Ive tried resetting both the TV and the amp but same issue ive also changed the hdmi 1.4 lead and it does the same. im completely stumped ive even tried optical from the tv to the amp and this works if you disconnect the HDMI cable from the TV

Any ideas? (both firmwares are up to date

thanks

Your post is somewhat confusing .. not sure what you mean by "when the channel is selected on the amp"? The HDMI (ARC) feature is a way of passing "audio" from the TV (eg. roof antenna, smart apps(Netflix, Hulu, Vudu, Pandora)) back to the AVR via the HDMI cable that connects the Monitor Out HDMI jack on the AVR to the HDMI(ARC) jack on the TV. This feature is enabled on the TV by setting the HDMI-CEC feature (VierraLink) to ON as well as setting the audio to "external speakers" and on the AVR by setting the RIHD feature to ON. When working correctly, when the TV and AVR are powered ON, the AVR will change to the TV audio input to allow the audio source "from" the TV to pass to the AVR.

You also may want to try unplugging the AVR for 10 minutes and if still no joy, try resetting the AVR (see Troubleshooting section in the Owner's manual).

Hi by changing channel I mean changing imput so cable / tv / pc etc for the brief second you press it the picture comes back on then goes off

now when first set it up - it worked fine and the amp auto selected the TV channel setting and worked fine then it just stopped working

I will try the unplug option as ive already tried resetting both the amp and the tv but no joy.

Unless your cable box and HTPC are connected directly to the TV, HDMI(ARC) has nothing to do with these sources.
