MZ-E505 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.
case (rear) (silver) ornamental belt (violet)

ABOUT VIOLET-COLOR-TYPE Not a whole set of the violet-color-type is colored violet, but only the ornamental belt and window (ornament) is violet, and the upper panel, the case (rear) and the battery case lid are colored silver.
upper panel (silver) window (ornament) (violet) battery case lid (silver)

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-4E) 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.

Replacement of CXD2671-210GA (IC601) used in this set requires a special tool.

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)

OPTICAL PICK-UP FLEXIBLE BOARD
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. 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 (S809 on MAIN board) with a tape in advance.

When entered in the TEST MODE, this set provides the Overall Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode, the system discriminates between CD and MO discs, performs adjustments in sequence automatically, and displays the faulty location if any fault is found. In the Manual mode, selected adjustments can be performed automatically. The attached remote control is used to operate the TEST MODE. Unless otherwise specified in the text, the key means that on the remote control. Remote control LCD

4-2-1. How to set the TEST MODE To set the TEST MODE, two methods are available. 1 Solder bridge and short TAP601 (TEST) on the main board. Then turn on the power. MAIN BOARD (Component Side)

Press and hold down X key to hold the current display while the key is being pressed. 4-2-3. How to release the TEST MODE When method 1 was used: Turn off the power and open the solder bridge on TAP601 on the main board. Note: The solder should be removed clean. The remaining solder may make a short with the chassis and other part. When method 2 was used: Turn off the power. Note: When the power supply is switched on in the state where all electrical adjustments have not finished, it is displayed on LCD as "NV Error'' and the usual operation can't be performed. When a power supply is accidentally turn off in the middle of electrical adjustments, it is again set as test mode and electrical adjustments is mode to complete.

All resistors are in and 1/4 W or less unless otherwise specified. C : panel designation. A : B+ Line. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Total current is measured with MD installed. Power voltage is dc 3 V and fed with regulated dc power supply from external power voltage jack. Voltages and waveforms are dc with respect to ground in playback mode (servo circuit ON). no mark : PLAYBACK : Impossible to measure Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. Circled numbers refer to waveforms. Signal path. E : PLAYBACK * Replacement of IC601 used in this set requires a special tool. The voltage and waveform of CSP (chip size package) cannot be measured, because its lead layout is different form that of conventional IC.
