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. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree 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 viscous (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.

MZ-S1 SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. (See Fig.1) · In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See Fig.2) · The shipment data will be cleared when the NV is reset. Therefore, change the NV adjusted values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 20) · This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC804) was replaced. (See page 30)

This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the microcomputer detect it and record its cause as history in the nonvolatile memory. By checking this history in the test mode, you can analyze a fault and determine its location. Total recording time is recorded as a guideline of how long the optical pickup has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred. Clear both self-diagnosis history data and total recording time, if the optical pickup was replaced. · Self-Diagnosis Result Display Mode Setting Method 1. Set the test mode (see page 15). 2.

REWRITING THE PATCH DATA AT REPLACEMENT OF MAIN BOARD OR NONVOLATILE MEMORY (IC804)
This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC804) was replaced. Caution: The application that meets the microcomputer version in this set must be used when rewriting the patch data. Rewriting the patch data using the application not suitable for the microcomputer version could cause the set to malfunction. For a checking method of the microcomputer version, see "SECTION 4 TEST MODE" (page 15). · Preparation 1. USB cable (attached to the set) 2. Personal computer in which the Net MD Driver has been installed. (For further information, see "System requirements" (page 5) in "SECTION 1 SERVICING NOTES") 3. Application "PatchWriter" for patch data rewriting · How to Get the Application "PatchWriter" for Patch Data Rewriting Contact our service technical support division to get the application. · Pre-Check 1. Check the microcomputer version in this set. (For a checking method of the microcomputer version, see "SECTION 4 TEST MODE" (page 15).) 2. Check that the Net MD Driver has been installed in the personal computer. 3. Make sure that the set is in the Normal mode.
Note: Do not rewrite the patch data in the Test mode.

· Rewriting the Patch Data 1. Connect the set to the personal computer with the USB cable. 2. Start the application "PatchWriter". 3. Make sure that the following window opens. 4. Click the [Usb Connect] button.
