Notes on chip component replacement

• Never reuse a disconnected chip component.

Q

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

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

TEL 13942296513 QQ 376315150 892498299

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 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 IC3511 AND IC3513 ON THE HDMI RE BOARD

IC3511 and IC3513 on the HDMI RE board cannot exchange with single. When IC3511 and IC3513 on the HDMI RE board are dam-

TEL

aged, exchange the entire mounted board.

For Schematic Diagrams.

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

• Voltages 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.

Voltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.

• Signal path.

J : AUDIO (DIGITAL) F : AUDIO (ANALOG) f : TUNER E : HDMI N : MIC

For Printed Wiring Boards.

Note:

• X : Parts extracted from the component side.

• Y : Parts extracted from the conductor side.

• f : Internal component.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

• Indication of transistor.

CEB

These are omitted.

Caution:

Parts face side: (SIDE A) Pattern face side: (SIDE B)

Parts on the parts face side seen from the pattern face are indicated. Parts on the pattern face side seen from the parts face are indicated.

• Circuit Boards Location

Caution:

Pattern face side: (Conductor Side) Pattern face side: (Component Side)

Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.

Note: The components identiﬁ ed by mark 0 or dotted

line with mark 0 are critical for safety.

Replace only with part number speciﬁ ed.
