This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
WARNING
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which may
cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with
the solder. Also, when soldering do not inhale any smoke or fumes produced.
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must
be of identical designation.
REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces
de remplacement doivent avoir la même désignation.
(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts 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 60Hz outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.
Reading should
not be above
0.5mA
Earth
ground
Device
under
test
Also test with
plug reversed
(Using AC adapter
plug as required)
Leakage
current
tester
Test all
exposed metal
surfaces
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 characteristics. 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 parts which have these special safety
characteristics are identified in this Service Manual.
Electrical components having such features are identified
by marking with a
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
information, always consult the current PIONEER Service
Manual. A subscription to, or additional copies of, PIONEER
Service Manual may be obtained at a nominal charge from
PIONEER.

NOTES:•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%).
• The information shown in the list is basic information and may not correspond exactly to that shown in the schematic diagrams.

7.2 TEST MODE
7.2.1 TEST MODE
7.2.1.1 How to Enter the Test Mode
Even that is possible though there are the following two methods.
(1) Receive "A55F" command with the remote control unit.
(2) Short-circuit the TEST MODE points on the foil side (pin 19 of
IC5001 and ground) of the DISPLAY Assy. Plug the power
cord into the AC socket.

2. DSP Check
Press the SURR. MODE key → Enter the DSP check mode.
DSP check mode
Outputs TEST TONE in the DOLBY VIRTUAL state.
Output repeatedly TEST TONE in order of LEFT → CENTER →
RIGHT → SURROUND.
Confirm whether DSP moves normally at the time of the
SURROUND output.
Press the SURROUND MODE key twice → Release the DSP check
mode. FL and LED are normal display.
* A key except for the designation normally moves.
7.2.1.3 Release The Test Mode
Turn the STAND BY/OFF key to OFF during the power on or unplug
the power cord from the AC socket.
7.2.2 SINGLE OPERATION METHOD
HTV system doesn't move if it is not the combination of HTV-C1
and HTV-A1 fundamentally.
AC26V is added to the sub-transformer (T2) when the HTV-C1 is
separate and you must diagnose it. (All the functions can't be
validated.)
• When the test mode is entered, FL displays with "TEST 1" for 1
second.
• LED keeps going on and off in the Test Mode.
• At this time, the setting of VOLUME becomes 10.
• SURROUND mode becomes DOLBY VIRTUAL ON.
7.2.1.2 Test Mode Operation
FL Segment Check
Press the DISPLAY key → Switch the movement of (1) to (5)
cyclically.
(1) All lighting the FL and LED
(2) All light-out the FL and LED
(3) (segment check 1) "ABCDEFGH" display
(4) (segment check 2) "IJKLMNOP" display
(5) Normal display
1. Check The AUTO STANDBY Function
(1) Press the INPUT key →
Turn the POWER off and it becomes AUTO
STANDBY mode.
FL displays with "AUTO".
(It becomes the condition that it passes for three
minutes during POWER ON with no signal.)

Auto Standby Function
The unit is equipped with a function that will automatically turn the
power ON/OFF (Standby) according to the presence or absence of
an input signal.
÷ When the power is ON, the AUTO indicator will be illuminated.
Standby status will automatically be engaged if there is no input
signal for 5 minutes.
÷ If the selected input terminal receives an input signal while the
AUTO indicator is illuminated (Standby status is engaged), the
power will automatically be turned ON.
÷ If power to the unit has been turned OFF (Standby status is
engaged) using the STANDBY/ON button on either the unit or the
remote control, Standby status will remain engaged even if the
selected input terminal receives an input signal.
