SERVICING NOTES
MZ-E505
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-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.
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.

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 dam-
aged 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 conve x part of the open/close detect switch
(S809 on MAIN board) with a tape in advance.
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)

TEST MODE
MZ-E505
4-1. GENERAL
• 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.
4-2. SETTING THE TEST MODE
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) –
Remote control LCD
• 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.
2 In the normal mode, operate the keys on the set and those on the
4-2-2. Operations when the TEST MODE is set
When the TEST MODE is entered, the system switches to the display check mode within the TEST MODE. From this mode, the
other Test modes can be accessed.
When the TEST MODE is set, the LCD repeats a cycle of the following displays:

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 per-
formed.
When a power supply is accidentally turn off in the middle
of electrical adjustments, it is again set as test mode and elec-
trical adjustments is mode to complete.

4-5-1. Outline of the function
This mode is designed to adjust the servo system automatically by
going through all the adjustment items.
Usually, this mode is used to perform automatic adjustments when
servicing the set.
For further information, refer to section 5. ELECTRICAL ADJUSTMENTS. (See page 18)
4-6. SELF-DIAGNOSTIC DISPLAY MODE
4-6-1. Outline of the function
The Self-diagnostic system is used in this set. If an error occurs
during playback, this system detects the fault through the
microprocessor’s mechanism and power control blocks and stores
the cause in EEPROM in a history format.
This history, which can be viewed in the TEST MODE, provides
the means of locating the fault in troubleshooting.

5-6-1. LED voltage check
Connection:
Procedure:
1. Confirm the power voltage is at 1.5 V.
2. Set to the test mode.
3. Set the Manual mode and set the item No. to 071.
Connect a digital voltmeter to TP902 (VCOUT) and TP815
(LEDADJ) on the MAIN board and confirm the voltage (high
luminosity RED voltage value).
