No power. The ignition might not be turned to ON/RUN or

The picture does not fill the screen. There are black
borders on the top and bottom or both sides, or it
looks stretched out. Check the display mode settings in the setup menu by
pressing the display menu button on the remote control.
In auxiliary mode, the picture moves or scrolls. Check the auxiliary input connections at both devices.
The remote control does not work. Check to make sure there is no obstruction between
the remote control and the transmitter window.
Check the batteries to make sure they are not dead or
installed incorrectly.
After stopping the player, I push Play but sometimes
the DVD starts where I left off and sometimes at
the beginning. If the Stop button was pressed one time, the DVD player
resumes playing where the DVD was stopped. If the
Stop button was pressed two times the DVD player
begins to play from the beginning of the DVD.
The auxiliary source is running but there is no picture
or sound. Check that the RSE video screen is in the auxiliary
source mode by pressing the AUX button on the
remote control.
