SECTION 1
SERVICE NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
Lead free soldering
MAIN and PANEL boards of this product are lead free soldered
(contains no lead).
Lead-free solder have the following characteristics.
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.
• The melting point is about 40 ºC higher than conventional solder.
Conventional soldering iron can be used, but must be pressed for a longer time.
When using the soldering iron with a temperature adjustment function, set to about 350 ºC.
Note: Pressing the soldering iron too long may cause the board pattern (copper coating) to peel off.
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.
• Strong viscosity
As it has stronger viscosity than conventional solder, make sure the IC terminal does not solder bridge.
Laser component in this product is capable of emitting radiation exceeding the limit for
Class 1.
• Can be used with conventional solder
Though it is best to add lead-free solder only, conventional solder can also be added.
• Boards using lead-free solder are printed with the LF mark meaning “Lead Free”.
This appliance is classified as a
CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT
MARKING is located on the rear exterior.
This caution label is located inside the unit.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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 manufacturers’ instructions to use these instruments.
2. A battery-operated AC 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 AC voltmeter. The “limit” indication is 0.75
V, so analog meters must have an accurate low-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)
To Exposed Metal
Parts on Set
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 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.
