When I leave my UE40KU6400 off for a few hours and switch it on again I get no picture or sound, just a black screen. If I then select TV input manually I get the TV tuner picture and audio. This only happens if I leave the TV off for a few hours not if i switch it on and off again after a few miniutes.

Hi there @Mark2.
What software version is your TV on (Settings > Support > Contact Samsung)? And what other devices do you have connected to it?

Thanks!
Once you have turned it on and changed the source to TV go to Settings > Broadcasting > Auto Tuning > Standby Auto Tuning Off. Then return the TV to the HDMI source you wish to view.
Does this solve your issue?

Seems to have worked, but now when I switch to hdmi input to watch from the Amazon Fire TV box I get sound but no picture.

Have you tried using the Fire TV box with a different TV?
Also, try switching the source to TV and then back to HDMI, has this fixed the issue?
