Fixed: Panasonic TV Red Light Blinking

TV issues can seriously ruin your downtime, especially the irritating Panasonic TV red light blinking issue.

Here’s how to fix this common issue.

Start by power cycling your TV.

Unplug it completely and leave it for a few minutes.

Then, plug it back in and turn it on.

Corrupted memory can cause this red light blinking issue, and draining the TV of power can clear the corrupted memory.

TVs are complex pieces of technology, but thankfully, many solutions to this common problem are super simple.

The rest of this article will help you diagnose and fix the blinking red light issue.

Why Is Panasonic TV Power Light Blinking Red?

There are several reasons why your Panasonic TV might blink red, and believe it or not, the number of blinks actually indicates the exact problem you have.

  • One blink indicates that there is a problem with the inverter circuit on the LCD panel, prompting the need for a replacement.
  • Three blinks indicates that the voltage levels in the AP board are too high. This problem can be repairable with an ohmmeter and voltmeter, but if you don’t have experience working with an AP board, it might be worth contacting a repairman.
  • Four to six blinks indicates other problems with the AP board. If you see this problem, it’s definitely worth getting a technician to have a look at it.
  • Seven blinks indicate a problem with the MAINs: the +3.3V, the +5V, or +9V sources
  • Nine blinks will let you know that there’s a problem with the unit’s audio output circuit. If your speakers are broken, you will need to replace them.
  • Ten blinks will let you know that there’s a malfunction in the frame converter, which is on the A board. If there’s an issue with this, you may need to replace the entire A board.

How to Fix It

Sometimes, if the issue is caused by a software error or corrupted memory, a simple reset of your TV is enough to banish the blinking red light.

In other cases, you may need to replace components of the board to get the TV back in working order again.

The Basics

Before you do any in depth fix attempts, your best bet is to do a simple power cycle.

Unplug the TV and leave it for a few minutes so that it can drain of power.

After that time has elapsed, plug it back in again and turn on the TV to see if the issue is fixed.

If so, then it may have been a simple case of corrupted memory.

You should also try replacing the batteries in your remote control as well.

Sometimes, a faulty remote can cause some irritating issues with the TV, so refreshing the batteries is often a good idea to make sure there’s nothing wrong with the remote.

I recommend you follow the steps below to rule out any remote-related issues:

  1. Take the batteries out of the remote.
  2. Give your remote a good shake to make sure there is no dust or dirt inside.
  3. Press each and every button on the remote a few times to make sure none of them got accidentally suck.
  4. Place a fresh set of batteries into the remote.

Now try using the remote and see if the issue with the light is gone.

Cable Checks

Make sure to check your cables from time to time and clean the ports with a dry microfiber cloth.

To detect faulty cables, try using them on another device and see if they still work.

If the cable doesn’t work, then you’ve found your issue.

If you find a cable that’s faulty, replace it and see if the blinking red light goes away.

Contacting the Panasonic Support Team

Unfortunately, the blinking red light in your Panasonic TV often indicates a problem with your hardware.

These issues are not fixed by a simple press of a button and will require expert diagnostics to figure out and solve the problem.

As such, your best bet once you’ve tried these simple fixes is to get in touch with the Panasonic support team and see if they have any insights on how to fix it.

Visit the official Panasonic support team website and contact customer support.

Depending on the issue you’re having, they may have you answer a few additional questions to provide accurate troubleshooting advice.

In many cases, however, they will dispatch a technician to take a look at the issue and see what needs repairing.

Thankfully, you can start planning ahead for the cost of the repairs by looking at the number of blinks.

Problems affecting the entire AP board will tend to be more expensive, while minor fixes like replacing a blown capacitor or faulty cable are much more straightforward.

If your technician suggests that you replace the circuit board entirely, then it might be worth looking into getting a new television, since the cost of repairing an old one can sometimes be more expensive than the cost of replacing it entirely.

Final Thoughts

The blinking red light on your TV can be annoying, but if you have ruled out some of the basic fixes, you’ll want to contact Panasonic customer support and have them send out a technician to fix it.
