HOW  TO  DRAW  OUT  FORCIBLY  THE  DISC  TRAY
In the event that the disc tray does not come out due to any fail-
ure, three methods are available to draw it out forcibly. Use either 
method described below according to the symptom.
METHOD  1
If the power did not turn on or if the power is OFF:
1.  With the power cord unplugged, remove the panel (side L) / 
(side R) assembly, panel (top), and panel (front). (See “How to 
Remove 2-2, 2-3 (page 8), 2-6 (page 10)”)
2.  As shown in the fi gure, insert a thin rod into the hole at the 
lower part of CD block, and push it in the arrow A direction.

bottom.

Peel the cushion (CD) a 
little when it hides the hole.
METHOD  2
If the CD-ROM drive is turned on but the mother board does not 
start:
1.  Insert a thin fl at-tip screwdriver into a round hole at the bottom 
of the set.
2.  Through a hole at the bottom of CD-ROM drive, short the 
points (patterns) on the board of CD-ROM drive.

METHOD  3
If the mother board starts but the system software is abnormal:
Plug in the power cord while pressing the [Z] button.
Note: This method is same as “CD Start Mode” of test modes. Load the 
start disc and close the disc tray, and if the start disc is not recog-
nized, start the CD as usual.

DISCHARGE  PROCESSING
1.  Switching power block on primary side of main board
 
Though high voltage of 280V is applied to the electrolytic capacitor (C205), in about 3 seconds after the AC cord was unplugged, the 
voltage will lower to 3 to 4V.
 
However, in the case of standalone main board, the discharge time will be long because of small load.
 
The voltage at this time is about 290V.
 
The voltage becomes half in about 20 seconds after the AC cord was unplugged. After that, in about 5 seconds, the voltage will lower 
to about 3V rapidly.
 
Then, the discharge slows and accordingly the forced discharge processing is necessary.
•  Forced discharge processing method
  Connect a resistor such as 100Ω 3W to the terminals of C205 and execute the discharge processing. (Discharge for about 10 sec-
onds)
Note: The potential of about 145V exists across aluminum case of C205. You could get an electric shock if you touch the aluminum case of C205.
2.  Power block on secondary side of main board
 
In about 3 seconds after the AC cord was unplugged, almost all potentials will lower to below 3V, but after that the discharge slows and 
accordingly the forced discharge processing is necessary.
•  Forced discharge processing method
  Connect a resistor such as 100Ω 3W to the terminals of C308 and C310, and execute the discharge processing. (Discharge for about 
5 seconds)
 
For electrolytic capacitors other than C205, 308 and 310, the discharge processing is executed simultaneously with the above discharge 
processing, and therefore the forced discharge processing is not necessary.
