MZ-R900 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. • 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 page 7) FLEXIBLE board (Over write head) upper panel assy NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-4R) 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. Tape MAIN board S806 • Replacement of CDX2671-203GA (IC801) used in this set requires a special tool. laser-tap OPTICAL PICK-UP FLEXIBLE BOARD • On the set having the microcomputer version 1.000, some adjusted values were set in the manual mode at the shipment, but these data will be cleared when the NV is reset. Therefore, on the set having the microcomputer version 1.000, change the adjusted values following the Change of Adjusted Values immediately after the NV was reset. (See page 17) • If the nonvolatile memory was replaced on the set, the modified program data must be written to the nonvolatile memory. In such a case, write the modified data that meets the microcomputer version following the patch data rewriting procedure at the replacement of nonvolatile memory. (See page 22) CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. 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. 3 MZ-R900 SECTION 2 GENERAL Looking at controls This section is extracted from instruction manual.

In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted. • Operation in the test mode is performed with the set. A key having no particular description in the text, indicates a set key. • For the LCD display, the LCD on the remote commander is shown, but the contents of LCD display on the set are same. • When the test mode becomes active, first the display check mode is selected. • Other mode can be selected from the display check mode. • When the test mode is set, the LCD repeats the following display. Remote commander LCD display All lit 888 BASS12 Setting Method of Test Mode There are two different methods to set the test mode: 1 Short SL801 (TEST) on the MAIN board with a solder bridge (connect pin 3 of IC801 to the ground). Then, turn on the power. – MAIN Board (Conductor Side) – All off Microcomputer version display 003 V1.000 Destination code 002 : Except US, Canadian models 003 : US, Canadian models • When the X key is pressed and hold down, the display at that time is held so that display can be checked. Caution: On the set having the microcomputer version 1.000, some adjusted values were set in the manual mode at the shipment, but these data will be cleared when the NV is reset. Therefore, on the set having the microcomputer version 1.000, change the adjusted values following the Change of Adjusted Values immediately after the NV was reset (see page 17). Releasing the Test Mode + C830 + C809 C813 SL801 (TEST) 2 In the normal mode, turn on the [HOLD] switch.

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. Setting the test mode (see page 12). 2.
