SAFETY-RELATED COMPONET 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.

SERVICING NOTES

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 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 IC1131 ON THE DIGITAL AB BOARD

IC1131 on the DIGITAL AB board cannot exchange with single. When IC1131 on the DIGITAL AB board is damaged, exchange the entire mounted board.

NOTE OF REPLACING THE IC3511 AND IC3513 ON THE HDMI BOARD

IC3511 and IC3513 on the HDMI board cannot exchange with single. When IC3511 and IC3513 on the HDMI board are damaged, exchange the entire mounted board.

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and scan the input FM signal with automatic scanning.

4. Conﬁ rm that input frequency of A, B and C are detected and automatic scanning stops.

set

When the station signal is received in good condition, automatic scanning stops.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise speciﬁ ed.

• f : internal component.

• 2 : nonﬂ ammable resistor.

• 5 : ﬂ usible resistor.

• C : panel designation.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.

no mark : TUNER

• V oltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope.

V oltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.
