A Sony TV that won’t turn on can be a frustrating experience for any owner. We’ve already looked at several problems with Sony TVs, but let’s focus in on problems with turning the TV on.

Here’s exactly what to check and what to do.

Let’s dive in.

Basic Troubleshooting Steps

Check Power Source

  • Ensure the TV is plugged into a working power outlet.
  • Test the outlet by plugging in another device to see if it’s functioning properly.

Inspect Power Cord

  • Check the TV’s power cord for any visible damage.
  • Make sure the cord is securely connected to the TV and the power outlet.

Power Reset Your TV

  1. Unplug the TV from the power outlet.
  2. Wait for 1 to 2 minutes.
  3. Plug it back in.
  4. Try turning the TV on, either with the remote or using its power button.

You can also do a more thorough reset of your TV. Here’s how to find the reset button on the TV.

Check Remote Control

  • Replace the remote control’s batteries and ensure they’re inserted correctly.
  • Test the remote on another device to confirm it’s working.


Restart Your Sony TV

  1. Point the remote control at the illumination or status LED.
  2. Press and hold the POWER button for at least 5 seconds or until a “Power off” message appears.

Power surge or protection

Some Sony TVs have built-in surge protection or power-saving features that may prevent them from turning on immediately after a power outage or surge.

In such cases, you may need to wait for a few minutes before attempting to turn on the TV again.

Software or firmware issues

Occasionally, software or firmware glitches can prevent a TV from turning on.

Try performing a power reset by unplugging the TV from the power outlet, waiting for a couple of minutes, and then plugging it back in. This process can help clear temporary software issues.

Potential Hardware Issues

Power Supply Board

The power supply board is a crucial component in Sony TVs. It is responsible for providing the required voltage and current to the various hardware components.

Potential issues with the power supply board can lead to the TV not turning on. Some common problems include:

  • Faulty power cords or outlets: Ensure the power cord is firmly attached and the outlet is functioning.
  • Defective capacitors: A capacitor is an electronic component that stores and releases energy. A damaged or leaking capacitor can prevent the TV from turning on.
  • Burnt or damaged components: A visual inspection of the power supply board can reveal burnt or damaged components.

TV Main Board

The TV main board manages various functions and inputs, including processing video and audio signals. Issues with the TV main board can prevent it from turning on.

Common problems associated with the main board include:

  • Firmware issues: Outdated or corrupted firmware can cause issues with the TV’s functionality. Ensure the TV’s software is up to date.
  • Faulty input connections: Check to ensure all cables are firmly connected to the TV.
  • Damaged components: Visually inspect the main board for any burnt or damaged components.

To resolve these issues, you can try the following steps

  1. Perform a soft reset by pointing the remote control at the LED and holding the power button for at least 5 seconds. If that doesn’t work with your TV – check this guide to resetting.
  2. Perform a power reset by unplugging the TV, holding the power button down for 15 seconds, and then plugging it back in after waiting 2 minutes.

Remember, if the issue persists after trying these troubleshooting steps, it may be necessary to seek professional repair.

Contacting Sony Support and Repair Considerations

Warranty Information

When experiencing issues with a Sony TV not turning on, it is crucial to check the warranty status. If the TV is still under warranty, the user might be eligible for free support and repairs.

Warranty terms and coverage may vary depending on the model and purchase location, so it’s essential to consult the warranty documentation provided during purchase.

Service Centers

If the TV is not under warranty, contacting an authorized Sony Service Center is recommended. They have skilled technicians with proper training to diagnose and repair Sony TVs. To locate a nearby service center, visit Sony’s official website and enter the relevant information such as product model and location.

To troubleshoot the TV before contacting support, the user can try performing a soft reset by pointing the remote at the LED and pressing and holding the POWER button for at least 5 seconds until a Power off message appears. If the issue persists, the user may unplug the TV from the electrical outlet for at least 30 seconds and then plug it back in. Additionally, detaching all external devices from the TV before turning it back on may help resolve the issue.
