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 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
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 > 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
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.

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.
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.

No scratches or dirt on its appearance after receiving it for service.
1 Check the firmware version. The firmware version must be the latest one.
If it is not the latest one, be sure to update it.
2 Confirm whether the customer complain has been solved.
If the customer complain occurs with the particular source, such
as Dolby Digital, DTS, AAC and HDMI, input it for the operation
check.
The customer complain must not be reappeared.
Video, Audio and operations must be normal.
5 Check a supported music file playback (e.g. wav. flac. mp3, etc).
(Make the connections with a USB memory or an iOS device)
Audio and operations including OSD output must be normal.
6 Check the surround playback.
(Select Surround mode and check the multichannel operations
via the DSP circuit.)
Each channel audio and operations must be normal.
3 Check the analog audio playback.
(Make the analog connections with a CD/DVD/BD player.)
Each channel audio and operations must be normal.

This is just for general reference and does not including every single case.
In case of using 4K/60p-compatible TV and no picure.
The receiver’s HDMI input terminals support the 4K/60p signal. However, there are two types of terminals as follows.
Type 1: 4K/60p 4:4:4 24 bit signal (transmission speed up to 18 Gbps) can be transmitted: BD, DVD (HDMI IN 1), SAT (HDMI IN 2)
Type 2: 4K/60p 4:2:0 24 bit signal can be transmitted (4K/60p 4:4:4 24 bit signal is not supported, transmission speed up to 10.2 Gbps):
HDMI input terminals other than the above
NOTE: All input terminals are type 2 when HDZONE is turned on.
1. When a source device that does not support the 4K/60p 4:4:4 24 bit signal is connected to a type 1 terminal, the video image may become reddish,
sound may not be output, or 3D signals may not be output for some devices. For such devices, try the following.
*This is not a malfunction of the receiver.
Connect the device to a type 2 terminal instead of the type 1 terminal.
It is also possible to set all input terminals to type 2. Set the following “HDMI 4K/60p signal output setting” to “4:2:0”.
2. When the video image is not output, is interrupted, or there is noise, the cause may be the HDMI cable. (Some HDMI cables do not support
4K/60p 4:4:4 24 bit signal transmission.) In such cases, set the following “HDMI 4K/60p signal output setting” to “4:2:0”.
HDMI 4K/60p signal output setting
Operation is performed on the front panel of the unit. You cannot perform the setting if the multizone function is not set to MULTI ZONE OFF.
1 Switch the receiver into standby.
2 While holding down ENTER on the front panel, press STANDBY/ON.
The display shows RESET NO .
3 Use / to select ‘4K/60p’.
4 Use / to select the signal to set.
4:4:4 – Select this setting when connecting to a 4K/60p 4:4:4 24 bit compatible TV using HDMI. More high quality video images can be enjoyed.
4:2:0 – Select this setting when connecting to a 4K/60p 4:2:0 24 bit compatible TV using HDMI.
5 When you’re finished, press RETURN.
6 Press STANDBY/ON to switch on the receiver and your TV.
Make sure that the TV’s video input is set to this receiver.
