I am struggling to get Chromecast to work properly through my Denon AVR1911 receiver.

The sound is OK, but the picture is flickering in and out of shot with green, red pink etc colour splashes.

Tried the standard and ultra versions. Same result.

All good on the TV itself and casts OK through my iPhone.

Interestingly when I reset the device there is a short period of time (15 seconds) when it is rebooting, the screen is stable. But after that its back to the flickering in and out of picture.

Tried all the HDMI ports to no avail. SAT/DVD/BD all working fine.

I'm wondering if it is a voltage issue. The Chromecast is using its factory mains adapter and not USB into AVR.

Help! I need for RWC.

Cheers

John
