 PIONEER XV-BD212 BLU-RAY Home Cinema System

HOW TO USE THE SA RESET FUNCTION

 SA RESET PURPOSE
1) If we change system, we should do SA adjustment to get better performance of BD disc.
2) This is the operation to locate collimator lens of pick-up at the exact point.
3) We use this value to playback the BD disc after we store into the flash memory.
REQUIRED SA RESET
1) After changing Traverse.
2) After changing Main Board Assembly.
3) After changing Main Board Flash IC.

SA RESET PROCEDURE

SOFTWARE UPGRADE
Burn a DVD recordable disc or USB with a file that is named to ‘PIONEER_HB_6200B33.ROM’.
Insert a upgrading disc or USB.
Show help message for disc upgrade as follows.
< in the case of Back End program & Front End program >

Press enter key to upgrade and it will show progress information.
Do not turn off the power during firmware update.  After completing upgrade then power is off.

Troubleshooting

When you turn on your set, it will display “PLEASE WAIT” on front panel, and it will not boot-up normally.

IC500 (MPEG IC)
Solution
Replace IC500 on MAIN board.
How to troubleshoot (Countermeasure)
1) Please Check 1.2 V.
Please Check 3.3 V.
Please Check 1.5 V.
Please Check RESET.
Please check the frequency of 27 MHz crystal (X500).
2) If it doesn’t work even though 1.2 V, 1.5 V, 3.3 V power and RESET are no problem, IC500 BCM7633 could have problem.
3) If RESET isn’t high, you may need to replace IC101.
4) After changing it, if the set is still no booting, check main board.

MAIN Board
Solution
Replace MAIN board.
How to troubleshoot (Countermeasure)
1) Please remove IC500, IC502, IC503, and then check the Impedance between each signal (DATA, ADDRESS, and so on.).
2) If there is some Impedance (a few Ω or infinite Ω) especially power source trace, PCB via might be broken. You’d better change main board.

WIRED NETWORK CONNECTION ERROR
When you connect Accu Weahter, You-tube or Picasa through the wired LAN, the “no connection“ message appears.

JK250
Solution
Replace JK250 on MAIN board.
How to troubleshoot (Countermeasure)
1) Check you internet connection. Make sure it connect properly to modem or router.
2) If internet connection OK, please check the ethernet jack (JK250).
3) If there is soldering problem, please re-soldering pin JK250.
4) If after re-soldering problem still occurs, replace JK250.
5) If problem still occurs after change JK250, check BCM7633 IC (IC500).

BAD HDMI VIDEO / AUDIO OUTPUT
When unit is connected to HDMI TV using HDMI cable, picture shows bad color, no output or mixed color on the screen. But component output is OK.

JK803
Solution
Replace JK803 (HDMI Jack).
How to troubleshoot (Countermeasure)
1) Check JK803 pin soldering.
2) If there is short soldering on pin JK803, re-soldering pin JK803.
3) If problem still occurs, check CF809 ~ CF812, R831 ~ R838:
If issue still NG, replace IC801.

BAD HDMI VIDEO / AUDIO INPUT
When unit is connected to HDMI IN(1 or 2) using HDMI cable, picture shows bad color, no output or mixed color on the screen.

JK801 & JK802
Solution
Replace JK801 or JK802 (HDMI Jack).
How to troubleshoot (Countermeasure)
1) Check JK801 or JK802 pin soldering.
2) If there is short soldering on pin JK801 or JK802, re-soldering pin JK801 or JK802.
3) If problem still occurs, check R814 ~ R829:
If issue still NG, replace IC801.

COMPONENT REPAIR

ABNORMAL MD OPERATION
Abnormal disc reading or abnormal tray open/close.
Replace new MD and test if it is operated normally.
Component
1) Traverse assembly
2) FFC cable from MAIN board to MD
How to troubleshoot (Countermeasure)
1) Check the connection between main board and FFC cable,
2) Confirm the connection point.
3) If all the cable connections are normal, replace the traverse assembly.

Service hint (Any picture / Remark)
After changing MD(Traverse assembly), you must perform "SA Reset".
Refer to the next chapter "How to use the SA reset function".

"ALL BD DISC" READING ERROR
All the Blu-ray disc is not operated, but DVD and CD are operated normally.
If the LDO for APC of BD laser diode is abnormal, BD doesn't work.
If the LD current control is abnormal, BD doesn't work.
Component
1) MD (Traverse Assembly)
2) SIC707 – Adjustable LDO
How to troubleshoot (Countermeasure)
1) Check MD (Traverse, pick-up) first of all
2) Check input/output voltage of LDO SIC707 – (12 V, 8.1 V)
3) If output voltage is abnormal, check the periphery of SIC707 and replace it.
4) Check the BD LD Control input/output.
If input signal (LTHR) is ok, but no output (LDI_BD), check the TR SQ714, SQ716

"ALL DVD DISC" READING ERROR
All the DVD disc is not operated, but BD and CD are operated normally.
If the LD current control is abnormal, DVD doesn't work.
Component
1) MD (Traverse Assembly)
2) SQ712, SQ717
How to troubleshoot (Countermeasure)
1) Check MD (Traverse, pick-up) first of all.
2) Check the DVD LD Control input/output.
If input signal (LDEL0) is ok, but no output (LDI_DVD), check the TR SQ712, SQ717.

"ALL CD DISC" READING ERROR
- All the CD disc is not operated, but BD and DVD are operated normally.
- If the LD current control is abnormal, CD doesn't work.
Component
1) MD (Traverse Assembly)
2) SQ713, SQ715
How to troubleshoot (Countermeasure)
1) Check MD (Traverse, pick-up) first of all.
2) Check the CD LD Control input/output.
If input signal (LDEL1) is ok, but no output (LDI_CD), check the TR SQ713, SQ715.

ABNORMAL SERVO OPERATION
The actuator, spindle and sled operation of pick-up are abnormal.

After changing Motor Drive IC, the motors are abnormal operations.
Component
1) MD (Traverse Assembly)
2) SIC706 – AZ4580MTR-E1
How to troubleshoot (Countermeasure)
1) Check if the input/output voltage of SIC706 (pin5 and pin7) is 1.65 V.
