1. SAFETY PRECAUTIONS
The following check should be perfor med for the
continued protection of the customer and ser vice
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known ear th ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the ear th ground and all exposed
metal par ts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
D
Leakage
current
tester
Device
under
test
E
Reading should
not be above
0.5 mA
Test all
exposed metal
surfaces
Also test with
plug reversed
(Using AC adapter
plug as required)
Earth
ground
ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related character istics. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be obtained
by using replacement components rated for voltage,
wattage, etc. Replacement par ts which have these
special safety character istics are identified in this
Service Manual.
Electr ical components having such features are
identified by marking with a
on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
infor mation, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Ser vice Manual may be obtained at a

5. PCB PARTS LIST
NOTES:
A
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%).
560 Ω
56 x 10 1
RD1/4PU 5 6 1 J
561
47k Ω
RD1/4PU 4 7 3 J
47 x 10 3
473
0.5 Ω
RN2H R 5 0 K
R50
1Ω
RS1P 1 R 0 K
1R0
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω
562 x 10 1

7.1.1 PROTECTION CIRCUIT CONTROL SPECIFICATION
Microcomputer-related ports
2 Overload detection
FAN_DRIVE (Expansion IC) : For Fan on/off
(abnormality detection)
TEMP_IN (pin 94)
Input port (A/D) : To detect temperature
FAN_STOP (pin 95)
Input port : To detect Fan forced stop
OL_DET (pin 73)
Input port : To detect overloading at the amplifier
(Interrupt port)
DC_DET (pin 63)
Input port : For DC 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)
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.
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)

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 key
input 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.)
If 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

7.1.2 DIAGNOSTICS OF AMPLIFIER SECTION
A
When 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.
B
C
• 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 R46214627 (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.

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.
C
Help of Non-failure Decision
Adaptation Problem with Chip Set
Symptom when a sound is not output
(Symptom is different by each OS)
Operating environment and findings of PCM2902EG
PCM2902EG caution of operation
• 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
D
• There is a bug in early USB AUDIO driver of WINDOWS XP, and
contain noise once for several minutes. (Correspond with
WINDOWS 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?
Evaluation PC: Libretto PAL2060 TNML made by Toshiba
(1) CPU: Crusoe 600MHz made by Transmeta
Use chip set: Transmeta N/B (North Bridge)
M1533 (South Bridge) made by ALi
OS: Windows ME
(2) CPU: Cerelon 566MHz made by Intel
Use chip set: Aladdin Pro 5 (North Bridge) and M1533 (South
Bridge) made by ALi
OS: Windows ME
(3) CPU: K6-2 400MHz made by AMD
Use chip set: Aladdin 5 (North Bridge) and M1543 (South
Bridge) made by ALi
OS: Windows ME
When contain noise by a problem of the chip set side, there is a
problem in the PC side because even other USB audio equipment
contains noise.
Therefore, do not recommend use in the condition and environment
as mentioned above.
Reference
Confirmation 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.
