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
D
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.
Device
E

test
Reading should
Leakage current
not be above 0.5 mA
tester
Test all exposed metal surfaces
Also test with plug reversed (Using AC adapter plug as required)
Earth ground
(fusible de type lent) sur CCI indiquent que les pièces
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.

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.

Assembling of Digital Amplifier Block
A Note : The attachment positioning of the Digital Amplifier Block relates to
sound quality of the unit. If assembling Digital Amplifier Block by wrong
steps, sound quality would deteriorate. Therefore assemble it correctly
following the procedure shown below.
[1] Attach the D AMP_SS ASSY
(1) Allocate the D AMP_SS ASSY attached with the Heat Cond Sheet, Heat Sink
Spacer (PLS), Heat Sink 85 (AL) and the 19P FFC (ADD7795). Don’t fix it with
screws.
B Note: If the 31P FFC (ADD7786) is connected, disconnect the connector. (For
prevention of damage of the 31P FFC.)
