HOT TIPS Check for latest updates
If the set has "grainy" video, verify the sources first.
If they are good, check the OSD. if that is fine,
narrow the inputs if possible. Digital noise will show
up as artifacts that customers will describe as
"Grainy" and can occur on the HDMI inputs. If this
only occurs on the HDMI inputs, and you know the
sources are good, replace the main board. Also
1
check external HDMI Cable is < 40 feet.
