Determine what cables the customer is using to connect the BD

Tighten any loose cables. Make sure the customer is not connecting a
BD to VCR. Copy protection can distort the picture on older VCR models.

watching multiple discs?
NO
YES
One disc displaying the issue is a problem with the disc.
Make sure the discs the customer is using are compatible with the
BD by checking “playable discs” in the owners manual.
Multiple discs displaying the problem indicates a problem with
the BD player.
Does color appear when
watching a TV program?
NO
YES
If the cable or satellite programming is connected through
another input and the customer does not get color, the customer has a
problem with his television. If a TV program does have the color,
the problem may be the BD player, the cables being used,
or the TV itself.
Does color appear
when the BD is
connected to another TV?
NO
YES
Connect the BD to another TV and play a disc. Good color during
disc play back indicates a problem with the first TV. Please refer to the
owners manual for instructions on how to connect the BD to a TV.
If the BD has a problem on the second TV, then see service chart for
service information.
Has the customer tried
another set of cables?
NO
Have the customer try another set of cables. A bad cable can
also cause video problems. Test the cable with another device to
the TV to also determine if the TV is bad. If the BD is the problem,
please see service chart for service information.
