Why Panasonic TV Blinking Red Light [13+ Blinks Solved]

All the Panasonic TV models have a built-in “SOS Circuit” for fault diagnosing purposes on the unit. When there is any abnormality on one of the internal circuits, the “SOS-Circuit” in the Panasonic TV will detect it and output the error in the form of red-light blinking.

To indicate the exact fault, the LED indicator blinks several times, usually 2-14 times. Each time blink represents a specific error. You can diagnose it easily by counting the number of red-light blinking on the indicator.

So, to assist you in your diagnosing and resolving journey, we’re going to describe all the Panasonic TV red light flashing error codes in detail. You’ll find the same error codes applicable to many Panasonic TV models like Plasma or Viera.  

So, let’s take a glance at what they’re & what they mean.

  • Also, confirm that the ventilation system isn’t inhibited. You can clean the vents or the slots to reassure it.
  • Still, seeing 2 times blinking in the same pattern? Inspect the D board of the unit. Inspect the voltages which we have already mentioned above. Replace the D board when it is detected to be faulty.

2. Red Light Blinking 3 Times [3.3V SOS D Board]

In the case of the 3 times blinking, it’s a voltage-related issue on the D board. This error code is connected to the 3.3V on the D board. Either this voltage is lost or missed out, letting the TV blink 3 times.
