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.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT -540A. Follow the manuf acturers’ instructions to use these instruments.

2. A battery-operated A C milliammeter . The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated A C voltmeter . The “limit” indication is 0.75 V, so analog meters must have an accurate lo w-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

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 viscou-s (sticky, less pr one 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.

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

The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

NOTES ON REPLACEMENT OF THE MB BOARD

1. Flash Memory

New part of flash memory (IC202) on the MB board cannot be used. Therefore, if the mounted MB board (A-1132-163-A) is replaced, exchange new flash memory with that used before the replacement.

2. Adjustment

When replacing the mounted MB board (A-1132-163-A), since the adjustment value is not set up correctly, “Drive Auto Adjustment” in the Test Mode can’t be performed. In this case, initialize memory in the following procedures.

Procedure:

1. Connect a video monitor to VIDEO LINE OUT jack (J103).

2. Press the [TOP MENU], [CLEAR], I/1 keys on the remote commander (RM-ASP001) in this order with standby status to enter the T est Mode, then “DIAG START” will be displayed on the fluorescent indicator tube and the Test Mode Menu screen will be displayed on the video monitor.

3. Press the [2] key on the remote commander to select the “2. Drive Manual Operation”.

4. Press the [6] key on the remote commander to select the “6. Memory Check”.

5. Press the [CLEAR] key on the remote commander to initialize the memory.

Note: Refer to page 22 for detail of the Test Mode.

NOTE OF HANDLING THE AV BOARD (Part No. A1126-999-A)

When the AV board is replaced by a repair for a fee, throw away the AV board after obtaining consent of not returning of the AV board to the customer. When throwing away the AV board, be sure to throw away after destroying IC600 physically with the hammer etc.

This Player Can Play the

Region code

Your player has a region code printed on the back of the unit and will only play DVD VIDEOs (playback only) labeled with identical region codes. This system is used to protect copyrights.

DVD VIDEOs labeled will also play on this player.

If you try to play any other DVD VIDEO, the message “Playback prohibited by area limitations.” will appear on the TV screen. Depending on the DVD VIDEO, no region code indication may be labeled even though playing the DVD VIDEO is prohibited by area restrictions.

Example of discs that the player cannot play

The player cannot play the following discs:

•CD-ROMs/CD-Rs/CD-RWs other than those recorded in the format listed on the previous page.

•Data part of CD-Extras

•DVD-ROMs

•DVD Audios

Also, the player cannot play the following discs:

•A DVD VIDEO with a different region code.

•A disc recorded in a color system other than NTSC, such as PAL or SECAM (this player conforms to the NTSC color system).

•A disc that has a non-standard shape (e.g., card, heart).

•A disc with paper or stickers on it.

•A disc that has the adhesive of cellophane tape or a sticker still left on it.

•DVD-Rs recorded in VR mode (Video Recording format)

•Copy-Once programs recorded on CPRM* compatible DVD-Rs.

•An 8 cm disc (The 12 cm disc adapter should not be used for 8 cm discs because it

may cause the disc to jam or the player to malfunction).

*CPRM; Content Protection for Recordable Media

is a coding technology that protects copyright for Copy-Once programs.

Notes

• Notes about DVD+RWs/DVD+Rs, DVD-RWs/ DVD-Rs or CD-Rs/CD-RWs

Some DVD+RWs/DVD+Rs, DVD-RWs/DVDRs or CD-Rs/CD-RWs cannot be play ed on this player due to the recording quality or physical condition of the disc, or the characte ristics of the recording device and authoring software.
