Vertical Error 1, 2 , 3, 4, 5, 8, 53, or 11
Yes
Change the upper Y-Buffer if in the upper part of the screen. Change the lower Y-Buffer if in the bottom of the screen. If this does not resolve the problem, change the PDP panel.
Replace the SSB
No
Error 6
Yes
Is the 5V SW voltage present on Pin 5 of 1M46 on SSB at turn On?
No
Error 7
Yes
Yes
Replace the SSB
Is the 8.6 volt supply present on Pin 3 of 1M46 on the SSB at turn On?
No
Error 12
Replace the Power supply.
No
Replace the Power supply.
No
Yes
Yes
Replace the SSB
Power supply or SSB. Check 12 volt supply from power supply. Replace the SSB.
No
Error 14
No
Yes
Remove power from the set and disconnect 1M52 and 1M02 from the Audio Amplifier panel.
Does the set turn On?
Yes
Replace the Audio amplifier board.
No
B
Repair complete
Yes
Replace the SSB
Has the SSB been recently changed?
C
Yes
Enter the screen diversity code with remote by pressing 0 6 2 5 9 8 Menu followed by the 3 digit screen diversity code.
Did the picture return?
No
Repair the panel as Stand alone
Pg 3
No
C Change the Power supply
Disconnect and remove the SSB. Disconnect the audio amplifier.
Error 7
G
No
Disconnect the Y-Driver and run the Power supply stand alone. Is the error still present?
Yes
Yes
Yes
Disconnect the Logic board and run the power supply Stand alone. Is the error still present?

Yes
Change the Logic board.
REFER TO PAGE 6
Yes
Yes
Run the power supply in a stand alone mode. Is the error still present?
Yes Is there a solid LED and Flashing LED on the Logic board? LEDs located in the upper right corner of the Logic board.
No
Are all of the supplies to the Logic board present?
No
Replace the power supply.
No
Yes
J Disconnect one logic driver board at a time to determine which is defective.
Pg 4
G
Error 5 or 8
Remove the X-Driver board and run the power supply stand alone. Is the error still present?
Yes
Yes
Change the power supply.
No Change the X-Driver board.
No Error 6, 9, 10, 11, or 13 or other.
Change the Power supply.
Yes
I
J Change the Y driver board if the power supply voltages to the panel are ok.
Is “Y” drive present? Check this on the test point on the lower part of the Y buffer upper or lower.
Yes
Is the “X” drive signal present? Check this on the X board connectors to the panel.
No

Pg 5
Yes
Check for proper cable placement when reassembling.
Figure 1 - line in picture - Defective TCP
Disassembly tips Connector removal of the Y-Buffer boards. Gently pull up on each end of the panel ribbon connectors to the Y-Buffer as not to create stress on the ribbon connector.
Checking the V4 panel power supply 1. To switch on the power supply while on the plasma panel with the Logic board connected, place jumpers on J8003 and J8004. To switch on the power supply outside the plasma panel, insert an additional jumper on BJ8902. 2. If LED8001 and LED8002 does not switch on, replace the power supply.
Pg 6
3. The Alarm LED will blink if one of the supplies is missing or is overloaded on the power supply. Refer to the troubleshooting flow chart. 4. Placing a jumper on BJ8901 will disable the protection circuits in the power supply. This can cause additional damage. White screen switch On Place a jumper on the Logic board at the location shown. Place the jumper before applying AC power to the panel.
Power Supply adjustment locations V4 power supply adjustment locations. Refer to the power set label on the panel for the correct voltages.
