Troubleshooting

When the self-diagnosis function is activated to

prevent the system from malfunctioning, a five-

character service number (e.g., C 13 50) with a

combination of a letter and four digits appears

on the screen and the front panel display. In this

case, check the following table.

If the system still does not

operate properly after performing

the above measures, reset the

system as follows:

Use buttons on the unit for the operation.

1 Disconnect the power cord.

2 Reconnect the power cord.

3 Press x, DISPLAY and DISC 1 at the same

time.

4 Press ?/1 to turn on the system.

The system is reset to the factory settings except

for DVD settings. You should set the settings

you made, such as the preset stations, clock, and

timer.

To return the DVD setup to the

default settings*, perform reset

as follows:

1 Press DISPLAY in stop mode.

2 Press M or m repeatedly to select “SET UP”,

then press ENTER.

3 Press M or m repeatedly to select “RESET”,

then press ENTER.

4 Press M or m repeatedly to select “YES”,

then press ENTER.

It takes a few seconds to complete. Do not

press ?/1 when resetting the system.
