SECTION  1
SERVICING  NOTES
Notes  on  Disconnecting  Between  the  OP  Section  (DVBU101)  and  the  DMB18  Board
Note:  When disconnecting between the OP section (DVBU101) and the DMB18 board, be sure to make a solder brige for electrostatic 
prevention as illustrated in the fi gure (before disconnection).
 
On the contrary, when installing the OP section, never remove the solder bride until the OP section and the DMB18 board are 
 connected.
 
Be sure to remove the solder bridge after the OP section and the DMB18 board have been connected.
Service  Position  for  the  DVD  Mechanism  Deck  Section
Refer to the fi gure given below when disassembling the DVD mechanism deck section.
Perform solder bridging to prevent damage by electrostatic  
discharge when handling the BU as a single unit.

Notes  on  Installing  the  Two  Cooling  Fans  (FAN901  and  FAN902)  (HCD-GZR8D/GZR9D)
Note:  The HCD-GZR8D/GZR9D has two cooling fans (FAN901 and FAN902) used. The connectors of these fans have the same color 
and the same number of pins.
 
When installing these fans, check the marking of CN601 and CN602 on the MAIN board and ensure that they are located correctly.
 
The CN601 on the MAIN board is to be attached with the connector of FAN901 where as the CN602 is to be attached with the 
connector of FAN902.
