Signal from Blu-ray player doesn't pass through AVR to TV.

[Aria1066]

I have a Samsung BD-H6500 Blu-ray player and a Pioneer VSX-322-K AVR but I cannot get the signal to pass through to the TV.
Other devices (laptop and Chromecast) work OK.

Everything is connected using HDMI cables.
I have tried different HDMI cables between the BD player and the AVR and different cables between the AVR and the TV.

I have tried using different inputs on the AVR and different inputs on the TV.
I have turned the devices on in different sequences.

All I get on the TV is a message saying that a signal is being received 1080p@50Hz which keeps switching on and off.

If I connect the BD player directly to the TV the signal is fine.

Any suggestions on what else I can try?

All sorted now thanks. HDMI cable wasn't seated properly in BD player.
