Hi all,

I recently changed my parents TV from an old 1080p Hanspree 28" to new Sony W800 32" model (1366 x 768).
The TV is fed by a Gigablue Trio 4k box with a terrestrial and satellite feed.

On the Hanspree all looks good. When I switch the HDMI cable to the W800 model, only the terrestrial channels work.
The satellite channels all show 0% signal.

All I moved was the HDMI cable and amended no settings.
When I switched back to the old TV all is good again.

This has me completely stumped and I am out of ideas.
I have tried:
1) Setting the A/V settings to 720p (no sat signal on Gigablue).
2) Connecting the SAT cable directly to the TV (bypassing the Gigablue). The TV tuning shows no signal
3) Connected it to a 3 year old LG cheap TV (no sat signal on Gigablue)
4) Different HDMI cables give the same result

It makes no sense to me as the HDMI cable should not affect the SAT signal at the Gigablue, it should just supply the video

If anyone has any ideas, please let me know.

Thanks
