GMC Yukon Denali 2003 Owner's Manual page 230

Problem
After stopping the player, I
push Play but sometimes
the DVD starts where I
left off and sometimes at
the beginning.
The auxiliary source is
running but there is no
picture or sound.
3-88
Recommended Action
If the stop button was
pressed one time, the
DVD player will resume
playing where the DVD
was stopped. If the stop
button was pressed two
times the DVD player will
begin to play from the
beginning of the DVD.
Press the SRCE button to
change from the DVD
player mode to the
auxiliary source mode.
Check to make sure that
the auxiliary source is
connected to the inputs
properly.
Problem
My disc is stuck in the
player. The Load/Eject
button does not work.
Sometimes the wireless
headphone audio cuts
out or buzzes.
I lost the remote and/or
the headphones.
What is the best way to
clean the video screen?
Recommended Action
Press the Load/Eject
button on the DVD player.
Turn the power off, then
on again, then press the
Load/Eject button on the
DVD player.
Do not attempt to forcibly
remove the disc from the
DVD player. This could
permanently damage the
DVD player.
This could be caused by
interference from cellular
telephone towers or by
using your cellular
telephone in the vehicle.
See your dealer for
assistance.
Wipe the video screen
with a soft cloth that is
damp with water.
