4. D board Malfunctions

From the very top, you may have known the Panasonic plasma TV red light blinks 5 times, mainly occurring to the faulty D board.

D board malfunctions 

When there is a wrong diagnosis by the D board, or there is a loss of 5V on the D board, the TV starts blinking 5 times. This may also occur for a shorted 5V. Look through the D board to resolve the 5 times blinking on your Panasonic TV. 


  • Remove the screws on the back of your TV and remove the panel.
  • Check the D board. Using a multimeter to measure the voltage of the D board. Check if there are any short out or missing voltages. 
  • If it has faults, you may have to change this particular board. 
  • Disconnect the flexible cables [D31, D32, D33 & D34] of the D board. 
  • Remove the four screws of the D board as it is marked on the picture.

5. Flawed P Board

Among other reasons, a flawed P board can be a cause behind the 5 times blinking on Panasonic TVs. In case of a shorted voltage or loss of voltages on the P board, the Panasonic TV goes to the self-diagnosis circuit and starts blinking 5 times. 

 P board 

Check the voltage of the pins and connectors of the P board using a multimeter. If the P board is flawed, refurbish the P board or, if needed, go for the replacement.


  • First, try to run the panel by disconnecting the connectors P6, and P7. If the panel comes on, the problem area is the DS, DN, and slot board.
  • Otherwise, there is a problem in the panel section. 
  • Check the voltage on the P board. Look if the Pin1 on connector P12 is shorted to the ground. 
  • If there is no shorted out, proceed to the P5V line. Check if there is 5V output at pin5 of connector P25 of the P board.
  • If there is no voltage output, measure the resistance between pin5 of connector P25 and the chassis. 
  • If a shorted 5V is located, find out from where it’s on the P board. 
  • Also, check if the voltage at pin7 or connector P27 goes low. 
  • According to the damages, take steps to repair or replace the P board.

6. Defective PA & H Board

The PA board and the H board can be another reason for Panasonic TV’s red light blinking 5 times.

PA & H board 

When the P board is fine, but the other boards like these can’t get the P5V, it makes the TV diagnose it as a 5 times error code and for the red-light blinking.


  • If the P board is fine, disconnect all the connectors providing the P5V to all the other boards like PA & H board. 
  • Remove the connectors of P5V while measuring the resistance between pin5 of connector P25 and the ground. 
  • If you find the defective PA board or H board when the connector that provides the P5V to the board is removed, you’ll see the short circuit is no longer present. 
  • Check the PA board and the H board. 
  • Now replace the faulty PA board or the H board. Remove all the connectors of these boards.
  • In its place, install the new board and connect all the connectors properly. 

7. A Board Failure

The very last reason for Panasonic TV’s red light blinking 5 times is an A board malfunction. It also causes a loss of P5V on the A board.

  • Open the back panel of your TV and access the A board.
  • Check the components of the A board if there is a short out.
  • Check the voltages on the A board using a multimeter. Look through if there is any loss of voltage.
