TROUBLE SHOOTING SOFTWARE UPDATE AND POWER SUPPLY CIRCUIT 

TROUBLE SHOOTING
VFD DOES NOT DISPLAY OR NO BOOTING WHEN YOU TURN ON THE POWER BUTTON
VFD does not display or no booting problem occurs when you power on the BD player.
IC301
Solution
Please check and replace IC301 on MAIN board.
How to troubleshoot 
1) Please check 5.3 VA of C213 (CN201).
Please check 3.3 VA of IC208 pin1.
2) Check the 1.2 V, 1.5 V, 3.3 V.
If 1.2 V, 1.5 V, 3.3 V voltage doesn’t come out,
check P_CON_5.3V1 (IC301 pin33) and P_CON_5.3L1 (IC301 pin32).
> If you figure out those power control doesn’t come out any signal level (or voltage), please replace IC301 of MAIN board.
3) If X301 does not oscillate as the frequency of 12 MHz, first, check X301 and then replace IC301.
4) After changing it, if the set is still not booting, check MPEG IC(IC500).
After changing it, if VFD is not displayed, check SMPS power (-29VA, FD+, FD-).
NO BOOTING WHEN YOU TURN ON THE POWER BUTTON
When you turn on your BD-P, it will display “Hello” message continuously on front panel, and it will not boot-up normally.
IC601, IC602
Solution
Please check and replace IC601, IC602 on MAIN board.
How to troubleshoot 
1) please check 1.5 V of C651.
2) If 1.5 V voltage doesn’t come out, check P_CON_5.3V1 of IC301.
> If you figure out those power control doesn’t come out any signal level (or voltage), please replace IC301 of MAIN board.
3) Check DDR3_VREF of C619, DDR3_VREF must be 0.75 V.
If DDR3_VREF is not 0.75 V, check the R581 and R582.
4) If the set is still not booting, check DDR IC (IC601, 602).
NO BOOTING WHEN YOU TURN ON THE POWER BUTTON
When you turn on your BD-P, it will display “Hello” message continuously on front panel, and it will not boot-up normally.
X501, IC500
Solution
Please check and replace X501, IC500 on MAIN board.
How to troubleshoot 
1) Please check the soldering status of 27 MHz crystal (X501).
2) Please check the frequency of 27 MHz crystal (X501).
3) If the crystal doesn’t oscillate, replace X501.
4) After changing it, if the set is still not booting, check MPEG IC (IC500).
NO BOOTING WHEN YOU TURN ON THE POWER BUTTON
When you turn on your BD-P, it will display “Hello” message continuously on front panel, and it will not boot-up normally.
IC603
Solution
Please check and replace IC603 on MAIN board.
How to troubleshoot 
1) Please check the IC603 on your eyes.
2) Check the /CE signal of pin9 of IC603.
First, If the /CE signal is not operating normally during booting, try to change IC603.
3) After changing it, if the set is still not booting, check MPEG IC (IC500) or DDR IC.
AUDIO OUTPUT IS SMALL OR NO AUDIO OUTPUT
When disc is played, audio signal is small or audio output is not.
IC805
Solution
Please check and replace IC603 on MAIN board.
How to troubleshoot
1) Please check the IC805 on your eyes.
2) Check the 1.2VRMS level of pin20 of IC805.
If the 1.2VRMS is OK, check C806 (VBIAS).
3) If the set is still no audio output, try to change IC805.
NO CONNECTION WHEN YOU TRY TO OPERATE NETWORK CONTENTS
When you connect YouTube , BD-live or Netflix, the “no connection“ message appears.
JK805
Solution
Please check and replace JK805 on MAIN board.
How to troubleshoot 
1) Please check the ethernet Jack (JK805) on your eye.
2) If there is no soldering problem, replace JK805.
3) After changing it, if the set is still NG, check MPEG IC (IC500).
SHOWING BAD COLOR, NO OUTPUT OR MIXED COLOR ON THE SCREEN USING HDMI
When BD player is connected the TV using HDMI, picture shows bad color, no output or mixed color on the screen. But component output is OK.
JK803
Solution
Please check and replace JK803 on MAIN board.
How to troubleshoot 
1) Please check JK803, RA801, RA802 on your eyes.
2) If JK803, RA801, RA802 pins shorted because of solder problem, unsolder and remove shorted point.
3) If there is no soldering problem, replace JK803.
4) After changing it, if the set is still NG, check MPEG IC (IC500).
NO CONNECTION WHEN YOU TRY TO OPERATE NETWORK CONTENTS WITH WIRELESS
When you connect You-tube , BD-live or Netflix through the wireless,
the “no connection” message appears.
WiFi Module
Solution
Please check and replace WiFi module on FRONT board.
How to troubleshoot 
1) Please check the WiFi module on your eye.
2) If there is no soldering problem, replace WiFi module.

In case of BD670/BD690, check USB hub IC (IC902)
HDD IS NOT OPERATING
When you try to contact with HDD, HDD is not recognized.
IC901, HDD module
Solution
Please check and replace IC901 on MAIN board and HDD.
How to troubleshoot 
1) Please check the power of HDD module (5 V,12 V).
2) If there is no power, replace HDD module.
3) After changing it, if the HDD operation is still NG, check SATA Bridge (IC901)
