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.

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%).
Adjust L201 so that the DC voltage between Pin
21 and Pin 23 of IC201 (Test point Vtm) gets
within 0 ± 50mV.

7.1 DIAGNOSIS
7.1.1 SELF-DIAGNOSTIC FUNCTION OF PICKUP DEFECTIVE
Symptom
• Indicates "No Disc" in FL display.
• Player does not playback, etc..
Procedure of Self-Diagnosis
1 Press the → buttons (of the test mode remote control unit : GGF1067) in the test mode screen, and turn on the
laser diode (It light-up for nine seconds.).
2 Confirm the indicated value of the laser diode current (LDI).
3 When indicated value is more than 110, pickup is defective. → Release the Traverse Mechanism Assy.
Note : When a DVD disc is played in the test mode, this function is effective.
TEST1
This function is effective only for DVD pickup (650nm).

7.1.5 TROUBLE SHOOTING
Microcomputer troubleshooting
Symptom of problem
• The power supply does not enter .
• The standby LED lights even if the
POWER key is pushed.
• The microcomputer is not reset.
Thought cause
XV-HTD510, XV-HTD510-B
Check method
• Whether terminal RESET (11Pin) is "H" is confirmed.
The operation of the RESET circuit is confirmed if
not becoming "H".
• It enters the state of POWER OFF
soon even in case of the POWER
ON.
• DVD does not operate at all.
• Time is not displayed in FL DISPLAY
at the DVD function.
• The AC pulse is not input.
• The oscillation circuit of the microcomputer
does not oscillate.
• If the function is DVD, the 3.3DETECT input
is 2.9V or less.
• It does not communicate with the DVD
microcomputer.
• Whether the AC pulse is input to AC input terminal
(26Pin) is confirmed. If the AC pulse is not input,
the AC pulse generation circuit is confirmed.
• The microcomputer or the oscillation circuit is broken.
The microcomputer or the oscillation circuit is
exchanged.
• If the voltage of the 3.3DETECT (13Pin) terminal of
the microcomputer is 2.9V or less, the voltage is
adjusted to 2.9V or more.
