ELECTRICAL PARTS LIST ................................ 43 Notes on chip component replacement - Never reuse a disconnected chip component. - Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing - Keep the temperature of the soldering iron around 270 ˚C during repairing. - Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). - Be careful not to apply force on the conductor when soldering or unsoldering. SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PA RT NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. Notes on the AC power adaptor Use only the AC power adaptor and USB cradle supplied with the player. Do not use any other AC power adaptor since this may cause the player to malfunction. The player is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the player itself has been turned off. If you are not going to use the player for a long time, be sure to disconnect the power supply. To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

3 NW-HD1 SECTION 1 SERVICING NOTES -Replacement of CXR704060-201GA (IC1003), MBM29SL800BE-90PBT (IC1101), S1R72003BOOA100 (IC2001), CXR710160-211GH (IC3001), CXD1616GH (IC7001) and EDL1216CASA-10L-E (IC7002) used in this set requires a special tool. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. -Unleaded solder melts at a temperature about 40 ˚C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 ˚C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! -Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. -Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
