As the reason for 13 blinks on Panasonic TV, on some Panasonic TV models, it’s an indication code of communication error [Peaks Lite2] where the checkpoint is DG board. 

The error indication code can also be DN board SOS when the voltage in this DN board is down on some Panasonic TV models.

  • Check all the connections of the boards if they are snugly seated on the board or on the chassis so that you can eliminate this loose connection as a probable cause. 
  • Locate the DG or the DN board and see for the damages on these boards.
  • Measure the voltage of the boards using a voltage multimeter. 
  • On the DN board, check if the 3.3V, 2.5V, 1.8V, and 1.5V is down.
  • Check if there is any missing or loss of voltage on any ICs on the board. 
  • If the boards can be repaired, repair the faults on them. 
  • When the boards are out of repair, you may need to change the DG or the DN boards. 
  • In order to replace the boards, disconnect all the ribbon cables and the cables that are holding the boards. 
  • Now install the new board into its place and put everything back in its place properly once you are done.

  • Test each component on the A board in this manner until you find the source of the problem of 13 blinks on the Panasonic TV.
  • Now according to the fault, repair or replace the A board of your TV.
