Panasonic LCD TVs, particularly the X-Series and G-Series, use error codes to help diagnose internal faults. These error codes are indicated by the blinking LED light on the front of the TV. Each blink pattern corresponds to a specific hardware issue, making it easier to identify and fix the problem.
In this guide, we will explain what these error codes mean and how you can troubleshoot common issues in Panasonic X-Series and G-Series TVs.
Understanding Panasonic TV Blinking LED Codes
When a Panasonic LCD TV detects a fault, it enters a self-diagnostic mode. Instead of displaying an error message on the screen, the power LED will blink a specific number of times. Each blinking sequence corresponds to a different hardware failure, such as a power board issue, inverter board failure, or voltage instability.
Panasonic X-Series TV Error Codes
🔴 1 Blink – Inverter Board Failure
- Cause: The TV’s inverter board, responsible for powering the backlight, has failed.
- Fix: Inspect the inverter board connections and replace any faulty components.
🔴 3 Blinks – Power Supply Voltage Failure
- Cause: Issues with the TV’s power supply voltages (1.2V, 1.8V, 3.3V, 12V, or 6V Tuner voltage).
- Fix: Check the power supply board and measure the voltage levels. Replace faulty capacitors if needed.
🔴 4 Blinks – Digital TV Processing Board Failure
- Cause: The digital board (A-Board) is failing to receive 12V power.
- Fix: Test the 12V supply line and replace the A-Board if necessary.
🔴 5 Blinks – 6V Circuit Board Failure
- Cause: A failure in the 6V power circuit affecting multiple TV functions.
- Fix: Inspect the voltage regulators and replace any defective components.
🔴 9 Blinks – P-Board 17V Failure
- Cause: The P-Board, which manages power distribution, has failed at 17V output.
- Fix: Check the P-Board for burned-out components and replace them.
🔴 13 Blinks – Emergency SOS Error
- Cause: A severe internal failure, causing the TV to enter protection mode.
- Fix: Disconnect the power for a few minutes, then restart the TV. If the issue persists, a professional repair is recommended.
Panasonic G-Series TV Error Codes
🔴 5 Blinks – 9V Power Failure
- Cause: The 9V power supply to a critical circuit has failed.
- Fix: Inspect the power board capacitors and check for damaged voltage regulators.
🔴 7 Blinks – 3.3V Circuit Failure
- Cause: The 3.3V power supply to the main board (A-Board) has malfunctioned.
- Fix: Test the 3.3V regulator and replace any burned-out components.
🔴 8 Blinks – ZWPL3.3V IC4200 Failure
- Cause: A failure in the ZWPL3.3V circuit, affecting the TV’s IC4200 chip.
- Fix: Replace the IC4200 chip or consult a technician for a board-level repair.
Troubleshooting Tips for Panasonic LCD TV Errors
✅ Restart Your TV – Unplug the TV for 5 minutes and plug it back in.
✅ Count the LED Blinks – Identify the error code before attempting any repair.
✅ Check Power Supply Voltages – Use a multimeter to test voltage levels on the power board.
✅ Look for Burned Components – Inspect the capacitors, resistors, and fuses on the TV’s circuit board.
✅ Refer to the Panasonic TV Service Manual – Always use the official Panasonic repair guide for proper diagnostics.
Conclusion
Panasonic X-Series and G-Series TVs use LED blinking codes to indicate hardware faults. Understanding these error codes can help you diagnose and fix problems quickly. If your TV is showing a blinking LED light, count the flashes and refer to this guide to determine the cause.
If you are unable to resolve the issue, it is best to contact a Panasonic service center for professional repair.
