Panasonic TV Not Turning On – Best Ways To Fix 

Is your Panasonic TV suddenly not turning on? If you don’t know how to fix it, you’re in the right place. It is quite common that you sit down for a quick watch, but your TV just refuses to turn on. But don’t worry; it is not very hard to fix it. You just need to find the reason behind this.

Your TV might have stopped working because of issues like a Faulty Power Supply, Backlight Issues, or Internal Problems like damaged circuitry or components. 

You can fix these problems by doing a Power Reset, which will ensure your TV is free of any power problems. You can then check the electrical outlets through which your TV is connected. If it still doesn’t work, you can check the Backlight for issues.

In this guide, I will walk you through all the common problems in detail and a thorough step-by-step procedure to get your Panasonic TV back up and running. Let’s get started.

Why Isn’t Your Panasonic TV Turning On?

Here are the most reported reasons that users experience due to which their Panasonic TV doesn’t turn on:

  • Power Supply Issues. The most common culprit is a disruption in the power supply. It might be a defective energy outlet or issues with the TV’s power cable, interrupting the power flow.
  • Internal Faults or Malfunctions. Internal issues in the TV itself might be stopping it from powering up. These can be anything from problems with the TV’s circuitry to failures in essential components like the backlight or mainboard.
  • External Device Interference. Sometimes, devices connected to your TV cause problems, leading to the TV’s refusal to turn on. A connected device like a Chromecast or cable box can cause this trouble.
  • Potential Backlight Problems. While less common, a malfunctioning backlight may also be the reason behind the display staying blank, even if the TV itself is operational.
  • Electrical Circuitry or Component Damage. Damage to the TV’s electric circuitry or key components for various reasons can make the TV non-operational.

Step-by-Step: How to Fix Panasonic TV Not Turning On

1. Do a Power Reset

When faced with a Panasonic TV that refuses to power up, initiating a power reset can do wonders. Here’s the way to go about it:

  • Start by switching off your Panasonic TV and disconnecting it from the power supply. This step ensures a complete shutdown.

  • Once unplugged, press and hold the power button for your TV for about 60 seconds. This long press helps discharge any residual power within the TV, performing a thorough reset.

Sometimes, a more sophisticated approach is necessary to attempt a hard reset. Here are a few alternative ways to reset your TV:

  • Press and Hold the Volume Buttons. While the TV remains unplugged, hold one of the volume buttons simultaneously as you press and hold the power button.

  • Remote and TV Power Button Hold. Another approach involves holding the power button on the TV and simultaneously pressing and holding the red button on your TV’s remote for at least 30 seconds.

2. Check the Power Sources

If your Panasonic TV is still not turning on, it is important to check whether or not the problem is with the power supply. Here’s how:

  • Start by plugging another device into your TV’s power outlet. This quick check confirms if the outlet itself is running properly.
  • Once the device is connected, if it powers up, it indicates the outlet is just fine. This implies the TV is encountering an inner issue causing the power problem.
  • If the device doesn’t power up, the outlet is faulty. Either get it changed by an electrician or plug your TV somewhere else by disassembling it and taking it near another outlet.

When dealing with electronics, especially troubleshooting power-related issues, it is important to prioritize safety. Avoid attempting to disassemble the TV yourself, particularly if you’re not educated or experienced in handling electronics. Disassembling the TV poses a full-size risk of electrocution because of its inner electric components.

It is better to get assistance from a qualified technician or a professional service center. They have the skills and protection measures to diagnose and handle these things.

3. Check for Issues in the Backlight

If your Panasonic TV stays unresponsive, it doesn’t necessarily mean it’s totally inactive. A blank screen could imply backlight trouble. Here’s a way to troubleshoot:

Check the TV’s operation by shining a bright light behind the display screen. Ensure no obstructions hinder the light from going through openings. Then, look at the TV display from the front. If faint pictures or shadows are visible, the TV is on but has a backlight malfunction.

Repairing backlights is complicated and, depending on the TV’s model and age, might not always be price-effective. For higher-end TVs, repairing a backlight may be an option. However, the repair cost might exceed the TV’s cost for older TVs.

Seeking an expert opinion can provide clarity on this. Technicians can evaluate the extent of the issue and advise on the best course of action regarding backlight repair for your Panasonic TV.

Examining Further Issues

When your Panasonic TV still refuses to turn on, there are additional steps you can take to go deeper into the issue. 

A multimeter can be a valuable tool for those confident in handling electronics. Using a multimeter, check the voltages to ensure the power gets where it needs to go. Before attempting this method, it’s critical to exercise caution and familiarity with electronics.

Peripheral devices connected to your TV may sometimes cause trouble. Disconnect all external devices like Chromecast, cable boxes, or DVD players from your TV. In rare cases, these devices might interfere with the TV’s functionality, causing it to stay unresponsive.
