TABLE OF CONTENTSNOTES 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 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 unsol-
dering.
SAFETY-RELATED COMPONENT WARNING!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radia-tion exposure.
SAFETY CHECK-OUTAfter correcting the original service problem, perform the following safe-ty 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 TESTThe 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 instru-ments.
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)

SECTION 1SERVICING 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 fl exible board is easily damaged and should be handled with care.
UNLEADED SOLDERBoards 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)
: LEAD FREE MARKUnleaded 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 viscous (sticky, less prone to fl ow)
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.
NOTE OF REPLACING THE IC102 ON THE DMB19 BOARDIC102 on the DMB19 board cannot exchange with single. When this part is damaged, exchange the entire mounted board.
