Sony TV Not Turning On: How To Fix In Minutes

A Sony TV that won’t turn on can be a frustrating experience.

However, before you panic, there are several simple troubleshooting steps you can take to diagnose and potentially fix the problem yourself.

This guide will walk you through common causes for a Sony TV not turning on and provide step-by-step instructions on how to troubleshoot and resolve the issue.

Let’s move on…

1) Double-Check the Power Connection

While it may seem obvious, the first and most crucial step is to ensure that your Sony TV is properly plugged in.

It’s surprisingly easy to overlook this basic check, especially when you’re feeling stressed or panicked.

Begin by confirming that the TV’s AC power cord is firmly and securely plugged into a working wall outlet.

Give the cord a gentle tug to make sure it hasn’t come loose.

To verify that the wall outlet itself is functioning correctly, try plugging in a different electronic device, like a lamp or your smartphone charger. If the other device powers on, you can rule out the outlet as the culprit.

If your Sony TV is connected to a surge protector or power strip, disconnect it and plug the TV directly into the wall outlet.

If here is no improvement, then

  • Again disconnect the TV from the power outlet
  • Similarly disconnect all the HDMI and antenna cable from the TV.
  • Now wait for at least 5 minutes.
  • During this time, press and hold the TV’s power button for about 30 seconds.
  • Once you are done, power the TV back on.

That’s it, your TV should work now…

Also, carefully inspect the power cord itself. Make sure it’s not bent, frayed, or damaged in any way. A damaged power cord can be a safety hazard and should be replaced immediately.

2) Don’t Forget the Remote Batteries

Another often-overlooked culprit is the humble batteries in your Sony TV remote.

Even if your TV is plugged in correctly and the power outlet is working, a dead remote can leave you stranded.

If pressing the power button on your remote yields no response, it’s time to investigate the batteries.

Remove them from the remote and test them in another device, such as a different remote or a flashlight.

If the other device fails to work with the batteries, it’s a clear sign that they need to be replaced. Pop in a fresh set of batteries and try turning on your TV again.

If your remote uses rechargeable batteries, make sure they are fully charged.

Connect them to the charger and allow them to charge for the recommended duration.

3) Discharge the TV’s Capacitors (Proceed with Caution)

If the previous steps haven’t resolved the issue, it’s possible that your Sony TV’s power supply is the root cause.

More specifically, the capacitors within the TV may be holding a residual charge, preventing it from turning on.

Discharging the capacitors can sometimes resolve this issue, but it’s important to note that this is a technical procedure that should only be attempted if you are comfortable working with electronics and understand the risks involved.

To discharge the capacitors, you’ll need to access the TV’s internal components.

This typically involves removing the back panel of the TV, which may require unscrewing several screws.

Once you’ve gained access, locate the motherboard, usually a large circuit board with various components attached.

On the motherboard, identify the largest capacitor, typically a cylindrical component. Take note of the location number specified beneath it.

Now, carefully flip the motherboard over and locate the pins associated with the capacitor.

Using a conductive and insulated tool, such as a screwdriver with a plastic handle, gently short the legs of the capacitor by touching them together.

This will discharge any residual charge that may be present.

4) Toggle the Energy Saving Switch

Many Sony TVs come equipped with an energy saving switch, a feature designed to reduce power consumption when the TV is not in use.

However, if this switch is in the wrong position, it can prevent your TV from turning on.

Locate the energy saving switch, usually found on the back or side of the TV, and make sure it’s in the “on” position.

This will ensure that the TV is not in a low-power mode that prevents it from starting up.

If you’re unsure about the location or operation of the energy saving switch, consult your TV’s user manual for specific instructions.

Each Sony TV model may have slight variations in the design and functionality of this feature.

5) Give Your TV a Dusting

Believe it or not, dust accumulation inside your Sony TV can sometimes interfere with its power supply and prevent it from turning on.

Dust acts as an insulator, disrupting the flow of electricity and potentially causing malfunctions.

Fortunately, this is an easy fix.

Grab your trusty vacuum cleaner, preferably with a brush attachment, and carefully clean the vents and openings on the back and sides of the TV. These are the areas where dust tends to accumulate most.

If you suspect that dust may have infiltrated deeper into the TV, you can attempt to remove the outer frame.

This usually involves unscrewing the screws that hold the panel in place. Once the frame is removed, use a dry cloth to gently wipe away any dust or debris from the internal components.

It’s crucial to use a dry cloth to avoid any moisture coming into contact with the sensitive electronic components, which could lead to damage.

6) Check Your Video Source

In some instances, your Sony TV may technically be turned on, but you’re greeted with a blank screen instead of your favorite shows or movies.

This can be a perplexing situation, but it often has a simple solution.

The culprit is usually an incorrect video input source. Your TV may be receiving a signal but displaying it on the wrong input channel.

To rectify this, locate the “source” button on your Sony TV remote or on the TV itself.

Pressing the source button will bring up a list of available input sources, such as HDMI 1, HDMI 2, AV, or TV. Use the remote or the buttons on the TV to navigate to the correct input source for the device you’re trying to use.

For example, if you’re trying to watch a movie on your Blu-ray player connected to HDMI 1, make sure that HDMI 1 is selected as the video source.

Once you’ve selected the correct source, the content should appear on your screen.

If All Else Fails, Contact Sony Support

If you’ve diligently followed all the troubleshooting steps outlined above and your Sony TV still refuses to cooperate, it’s time to seek professional assistance.

Sony’s customer support team is renowned for its responsiveness and expertise.

They are well-equipped to help you diagnose and resolve any issues you may be experiencing with your TV.

When you contact Sony support, be sure to provide them with the model number of your TV and a detailed description of the problem.

Explain the troubleshooting steps you’ve already taken, as this will help them narrow down the potential causes and expedite the resolution process.

Depending on the nature of the issue and your TV’s warranty status, Sony may offer to repair or replace your TV.

They may also guide you through additional troubleshooting steps or refer you to an authorized service center.
