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 electro- static 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.

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 up- per panel, the case (rear) and the battery case lid are colored sil- ver.

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

The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care.

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 dur- ing 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, re- moving 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.

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)

MZ-E505 specifications

The Sony MZ-E505 is a portable mini-disc player that emerged in the early 2000s as part of Sony's innovative move towards digital audio solutions. This compact device combines functionality, versatility, and cutting-edge technology, making it a popular choice among music enthusiasts. The MZ-E505 stands out due to its sleek design and impressive features, setting the standard for portable audio players of its time.

One of the main characteristics of the MZ-E505 is its lightweight design, weighing approximately 160 grams. Its portability is complemented by an elegant, user-friendly interface, which includes a simple set of buttons for easy navigation through tracks and folders. The device features a bright LCD display that shows essential information such as track number, time elapsed, and battery life, ensuring users remain informed while on the go.

The MZ-E505's standout feature is its mini-disc technology, allowing users to record and playback high-quality audio. Mini-discs, introduced by Sony in the 1990s, offer an advanced storage solution that can hold up to 74 minutes of high-fidelity stereo sound on the standard format. The player also supports LP2 and LP4 modes, enabling users to double or quadruple the recording capacity, which is perfect for those who require more space for their music collections.

In terms of sound quality, the MZ-E505 utilizes Sony’s ATRAC (Adaptive Transform Acoustic Coding) compression technology, which ensures that audio playback is clear and precise. The device is equipped with a 20-second shock protection mechanism to prevent interruptions during playback, giving users peace of mind while enjoying their favorite tracks during activities like jogging or commuting.

Battery life is another crucial aspect, and the MZ-E505 doesn’t disappoint. It features a rechargeable battery that can provide up to 10 hours of continuous playback on a full charge. Additionally, users have the option to utilize standard AA batteries as an alternative power source.

The MZ-E505 also incorporates a variety of connectivity options, including an analog line-in for direct recording from external sources. This feature was particularly appealing for audiophiles who wanted to create their mix compilations.

Overall, the Sony MZ-E505 is a remarkable blend of portability, sound quality, and innovative technology, representing the quintessential qualities of early digital audio devices. Although the mini-disc format has since been largely superseded by other digital technologies, the MZ-E505 remains a cherished piece of audio history, celebrated for its unique capabilities and breathtaking design.
