I don't have much luck with UHD722 machines!

This time my lounge UHD722 suddenly sent all pictures to my TV with a strong green colour. Pulling the HDMI cable out and re-seating it made no difference. Replacing the HDMI cable made no difference.

I changed the HDMI TV input from 1 to 3 and for a short while this worked and then the green returned.

I mainly use the SKY puck so tried the Sony 4K player with the same green effect.

I then connected the SKY puck directly via HDMI and voila perfect picture which pushed me back to the 722. Good news, it wasn't the TV on the way out!

I turned all the system kit off and on again but no change.

I tried this again and things went from bad to worse as the green screen became a black no picture screen!!

After discussing this with a Meridian dealer he suggested a mains power cycle of the 722 which I did and suddenly the problem was gone! The classic IT turn it off and on again!

I share this information in case another HH experiences a similar problem and that this may save another HH a lot of time, frustration and head scratching to find a solution

I have no clue what set this off and obviously very happy that the machine is running well again.

Speculation very welcome.
