DIGITAL DISPLAY & MEDIA TRAINING MASTER
Is the disc
currently playing?
NO
YES
Ask the customer to press stop to stop the disc from playing.
Ask the customer to press the resolution button to change the resolution.
The BD player will not change resolutions while the disc is playing.
Is the customer using
component (red, blue,
and green) cables?
NO
YES
Discs with copy protection will not upconvert above 480p
when using component cables. The component output does not have
HDCP (highbandwidth digital content protection) compliancy
which causes the BD player to switch from 720p or 1080i to 480p.
Is the customer using
any sort of adapter cable?
NO
YES
RGB to DVI or RGB to HDMI adapters will not upconvert.
RGB outputs 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.
Is the customer using
an HDMI or DVI cable?
NO
YES
Regular discs can convert to 1080p over the HDMI output and
only the 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).
Is the customer using an
HDMI to DVI cable?
NO
YES
Some movie companies will not allow their discs to upconvert
past 480p. If only one disc poses a problem, then the issue is the disc.
The customer will need to try multiple discs.
Has the customer tried
multiple discs?
NO
One disc not upconverting means the disc may not upconvert.
Some movie companies will not allow their discs to upconvert.
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 needs service.
5-11. My Unit Won’t Upconvert
The customer has a problem with getting the unit to change resolutions to 480p, 720p, 1080i, or 1080p.
