Try the old unplug all connections, USB devices and unplug power for 15 minutes. Now plug just the power in and re-test. If that fails, you need to call in for service.

I have a UE40H5400 Samsung LED TV and i am experiancing an issue where i turn the tv on and it displays the samsung logo no issues, the screen then goes blank with the backlight on and all the buttons on the remote do is make the red light flash.
I can't access menus or see anything after the logo when it turns on.
Any ideas how to fix this?
Thanks
