DIGITAL DISPLAY & MEDIA TRAINING MASTER
5-11. My Unit Won't be up-converted
The customer has a problem with getting the unit to change resolutions to 480i/p, 720i/p, 1080i, or
1080p.
Is the disc currently playing?
YES
Is the customer using component
(red, blue, and green) cables?
YES
Is the customer using any sort of
adapter cable?
YES
Is the customer using an HDMI to
DVI cable?
YES
Is the customer using an HDMI
or DVI cable?
YES
Has the customer tried multiple
discs?
Ask the customer to press stop to stop the disc from playing.
NO
Ask the customer to press the resolution button to change the resolution.
BD-HTS will not change resolutions while the disc is playing.
Discs with copy protection will not upconvert above 480p when using
NO
component cables. The component output does not have HDCP
(high-bandwidth digital content protection) compliancy which causes
BD-HTS to switch from 720p or 1080i to 480p.
RGB to DVI or RGB to HDMI adapters will not upconvert. RGB outputs
NO
and inputs are not HDCP compliant. If the customer sees an error
message about HDCP, this is the issue. Copy protected discs will not
upconvert when HDCP is not found on the input or output.
Regular discs can convert to 1080p over the HDMI output and only the
NO
HDMI output. The TV has to have HDCP compliancy on the HDMI input.
The display has to accept the resolution (480p, 720p, 1080i, or 1080p).
Some movie companies will not allow their discs to upconvert past 480p.
NO
If only one disc poses a problem, then the issue is the disc.
The customer will need to try multiple discs.
One disc not upconverting means the disc may not upconvert.
Some movie companies will not allow their discs to upconvert.
NO
If multiple discs display the issue, remove the disc and change the
resolution with no disc in the unit. If resolution will not change, the unit
2-25
needs service.
