Pioneer Plasma TV Blinking Blue Light 8, 9 & 12 Times (Easy Fix!)

Pioneer Plasma TV blinks blue light 8 times when there is a faulty voltage regulator chip, a brief power outage, or a communication problem between the chips. Other than these, if your TV’s protection mode is On, the blue light may blink 8 times.

If the blue light on your Pioneer Plasma TV is blinking 9 times, the internal circuit board could be defective or the receiver box could be faulty. While blinking blue light 12 times on your Pioneer Plasma TV indicates a digital tuner communication error. Furthermore, the blue light may blink 12 times when there is any change in signal, or the TV’s main board has failed. 

In this guide, I will cover the troubleshooting of the issue of the blinking blue light on your Pioneer Plasma TV whether it is blinking 8 or 9 times. At the end of this post, you will also know why the Pioneer Plasma TV screen flickers and how you can reset your TV if you don’t have your remote!

Pioneer Plasma TV Blinking Blue Light 8 Times (Causes & Solutions)

First, let’s know the possible cause when your Pioneer Plasma TV blinks blue light 8 times.

The Voltage Regulator Chip

If somehow, the voltage regulator chip is defective, your Pioneer Plasma TV will start blinking blue light, and it will blink 8 times with no picture and no sound. Considering a faulty voltage regulator as the main cause of the blinking blue light 8 times, once you replace or repair the chip, the problem will solve for you instantly. 

The main board contains a voltage regulator chip, and if the chip is lousy or defective, the TV will start flickering or blinking blue light. So, you have to check if the chip is the issue and replace it with a new one if it is faulty. 

To do this, first, check the input and output voltage and note them down. When you replace the faulty regulator chip, make sure the input and out voltage are good as they should be. Once you change the faulty voltage regulator, the blue light will stop blinking. 

Note- Since these steps need excellent technical skills, I would recommend contacting a professional repairman so that you don’t mess things up. If you have such good skills, you can replace the defective chip yourself! 

The second possible cause for the issue is the power outage and let’s understand it in detail!

The Power Outage

If your TV is On, and the blue light is blinking 8 times then the power outage could be the culprit. If the power source stops working as usual, your Pioneer Plasma TV may experience a power outage, then it can result in the blinking blue light issue. This can happen when the cable connection between your TV and the outlet is insecure, the TV is not plugged into a surge protector or there is some kind of Power supply failure.

To solve the power outage issue with your Pioneer Plasma TV, you should perform a power reset. To do this, just unplug your TV from the main power source and detach all the wires or cables from your TV and wait for 2 minutes. While detaching all the cables, press the power button on your TV so that all the residual power could be drained out. Plug all the cables and turn on your TV. 

Also, you should check the cables and wires if they have any kind of defects or issues. 

Communication Hindrance between the Chips

This is another cause of the issue ‘Pioneer TV blinks blue light 8 times ‘. The TV has many chips internally connected, if somehow, the connection between these chips gets hindered (Any of the chips get defective), the TV starts blinking blue light 8 times. 

Dealing with chip communication problems is not a layman’s task, it requires excellent technical knowledge. So, to fix this issue, I would recommend contacting a TV technician, as the process may take hours and a lot of steps.  

However, in short, when you determine the exact cause of miscommunication, fix it and the TV will turn on and the blue light will not blink again. 

TV Has Gone into Protected Mode

There are several reasons why your Pioneer Plasma TV may be in protection mode. But it could happen majorly due to these:

• Accumulation of charges on the capacitors results in a jammed internal circuit. 

• Internal fault. 

• If the board chip reads the wrong voltage. 

• Internal voltage cut is identified by the protection circuit.

To fix this issue, the first thing to do is to power reset your TV, and if this doesn’t help, hire a technician or go to your nearest repair shop to determine the cause. 

If you have done all the above-mentioned techniques, the blue light should stop flashing or blinking. 

Pioneer Plasma TV Blinking Blue Light 9 Times (Causes & Solutions)

Pioneer Plasma TV blinks blue light 9 times mainly due to Malfunctioning Internal Circuit Board or there is any issue in the Receiver Box. So, once you determine the exact nib of the issue, the problem would be very easy to solve. 

Don’t worry I will help to figure out the causes for both issues and also tell you the actions that you should perform. 

The Internal Circuit Board

Malfunctioning the internal circuit board could be caused by several means in which, failure of internal components, the circuit board’s physical damage, power failure, overheating of the circuit board, or burnt components within the board are very common.  

So, to prevent a mess with your TV’s internal circuit board:

• Don’t use your TV excessively to prevent overheating.

• Find out the damaged internal components and replace them with a new ones. 

• Ensure that there is no lack of power. 

• Determine the burnt components and replace them with a new ones. 

The Faulty Receiver Box

A faulty Receiver sends wrong or inappropriate signals to the TV, as a result, the Pioneer Plasma TV blinks blue light 9 times. So, to check and ensure the issue, disconnect the DVD or receiver box from your Plasma TV. If the blinking light stops blinking, it could be understood that the receiver was the problem.  

Note- I always recommend performing the technical steps only if you have excellent knowledge in the field, otherwise, I always suggest taking the help of a professional repairman to prevent any other mess.
