5. PCB PARTS LIST

• LIST OF WHOLE PCB ASSEMBLIES

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation.When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

The following control processes are activated immediately before the relay system is turned on upon power-on. The time is 4.8 seconds after power-on. (Control of the relay system is enabled 5.2 seconds after power-on.)Only DC detection is enabled 2 seconds after power-on to activate it before other protection functions.

1 Thermal and Fan detection, and Fan control

1) Thermal detection and Fan controlValid with American and Japanese models only.

2) Fan detectionIf the fan is forcibly stopped, the FAN_DET port becomes "L" Detecting "L" the microcomputer performs the following operations: 1. System muting on 2. Protection relays off

The warning indication "FAN STOP" appears (flashing) on the FL display.If this status continues for more than 3 seconds, the power is turned off (for Standby mode).If the port becomes "H" within 3 seconds, the unit resets automatically.FAN_DET port performs the chattering check for 7 msec.In addition, there is the case that detection delays for maximum 20 msec because performs monitor of FAN_DET port with a main loop.

2 Overload detection(abnormality detection)

If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes "L"Detecting "L" edge interrupt in an interrupt process, the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer) 3. Power off (Standby mode)

3 DC detection (defect detection)Only DC detection is enabled 2 seconds after power-on.If there is a fault in the power amplifier or a high-level signal lower than5 Hz is input, the DC_DET port becomes "L"Detecting "L" the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer)

The warning indication "AMP ERR" appears on the FL display.

If this status continues for more than 3 seconds, the power is turned off (for Standby mode) and flashes the standby LED.Do not accept the key input afterward.(Flash it always till turns the primary side off.)If the port becomes "L" within 3 seconds, the unit resets automatically.

DC_DET port performs the chattering check for 1 msec.In addition, there is the case that detection delays for maximum 20 msec because performs monitor of DC_DET port with a main loop.Even if turns the primary side off and turns on once again, standby LED flashes as it is.If detects DC once and turned the power off, do not accept the keyinput afterward.However, power on is possible when the following key was pressed to be able to key input in the protection line and service. 1. Test mode (remote control code : A55F) 2. When the STEREO/DIRECT key and SIGNAL SELECT key

are both held pressed for 2 seconds.(Be effective when turned the power off by DC detection regarding 2.)

Valid with European and other general-area models only.

* By poor contact of Thermistor and alien substance mixture, there are the following cases displayed FL. Become STBY after having done flushing with "THDCT NG" for three seconds.By opening of thermistor junction or energization in very cold place (less than -15°C),TEMP line becomes high impedance. And when TEMP port became equal to or less than 0.1V.

7.1.2 DIAGNOSTICS OF AMPLIFIER SECTIONWhen DC detection worked (STBY IND. flashes for a long time) in the protection circuit of foregoing section (or there is not the speaker output, probably only 1CH), failure (damage) of the power amplifier section is considered.

Because this receiver cannot diagnose the amplifier section by an electricity state by structure, please diagnose it in the following steps.

Caution:When release the STBY (flashes) state before repair, Because there is the case that the damage progresses when turns the power on once again, please be careful.

• According to a symptom, perform the following confirmation beforehand.

1. Are not Fuse and IC protector opening it?2-a. When can turn on electricity, confirm that supply voltage of

the point that can measure is appropriate.2-b. Furthermore, confirm that voltage ((in a no signal) DC and

the appropriate signal output) between GND and R4621-4627 (Either of the amplifier side and the speaker terminal side is possible) (Or remove either of CN4601-4604). And limit failure CH.

If was able to limit failure CH, diagnose the CH in the following steps.

• Use the tester basically and check that each part is not damaged (resistance value / open / short circuit).

About parts with damaged possibility, explain FL ch to an example in order.1. R4131, 4132 (ACN7107: 0.1 Ω, 1W chip drain resistor)

USB AUDIO data

About PCM2902EG• With codec of USB BUS POWERED, power is supplied from Vbus of USB, and work. (work with a power supply of VSX-45TX irrelatively.)• Be USB codec, but analog I/O and digital (SPDIF) input are not using in VSX-45TX.• When only connects to PC and receiver (VSX-45TX) is turned on, the output of TC7SET08F outputs.

Music playback(A music file of MP3, etc.)

Help of Non-failure Decision

Symptom when a sound is not output (Symptom is different by each OS)• Confirm a driver whether PC is recognizing it. (With a device

manager).• Is a switch of sound sourse performed properly? (Control Panel,

Sound or Multimedia)• Is volume control of PC adjusted?• How is other PC?• In the state that does not change PC setting, is sound output in

other VSX-45TX?• When uses CD-ROM and playback a music CD, and a sound is

not output, is digital playback of CD-ROM checked?

When contain noise• There is a bug in early USB AUDIO driver of WINDOWS XP, and

contain noise once for several minutes. (Correspond withWINDOWS UPDATE.)

• An affinity problem with chip set• Adaptation problem with chip set (refer to next item)• Performance issue of PC. (Release resident software as

measures.)• Noise when using the other software during music playback.

(Do not guarantee or do not use the other software)• Do contain the same noise even if changes the PC?

ReferenceConfirmation item of the USB part with Function checker.Supply a power supply (+5V: pin 3, GND: pin 4) of IC1681 (PCM2902EG), and connect D+ (pin1) to GND.Confirm that X1681 (ASS7047) starts oscillating.

Adaptation Problem with Chip Set

PCM2902EG caution of operationOperating environment and findings of PCM2902EG

Evaluation PC: Libretto PAL2060 TNML made by Toshiba

(1) CPU: Crusoe 600MHz made by TransmetaUse chip set: Transmeta N/B (North Bridge) M1533 (South Bridge) made by ALiOS: Windows ME

(2) CPU: Cerelon 566MHz made by IntelUse chip set: Aladdin Pro 5 (North Bridge) and M1533 (South Bridge) made by ALiOS: Windows ME

(3) CPU: K6-2 400MHz made by AMDUse chip set: Aladdin 5 (North Bridge) and M1543 (South
