reasons why sony tv isn't turning on

If your Sony TV doesn’t turn on, several possible causes exist. For example, the issue may be due to a bad power supply, a faulty power cord, a damaged circuit board, or a bad mainboard. Additionally, the TV may not receive enough power or be set to the wrong input source.

However, these are the eight primary reasons your TV is not turning on:

  • Defective Power Supply.
  • Loose Cables.
  • Faulty Main Board.
  • Blown Fuse on Main Board
  • Power Outage.
  • Faulty Remote Control
  • Overheating
  • Firmware Issues

Steps to Troubleshoot the Sony TV Not Turning On Issue

To troubleshoot your Sony TV that isn’t turning on, check the power cord, power button, and remote control. If these are all functioning properly, factory reset your TV.

Before diving into a detailed solution, look at the table below for a better understanding of the problem.

Reasons Solutions
Outdated Firmware Update the TV
Faulty cable or outlet Replace them
Damaged mainboard Repair It

Step 1: Troubleshoot related things first.

Typically, a faulty power outlet, damaged power cable, or malfunctioning remote control is the cause of this issue.

Therefore, checking these components before examining the TV is essential.

♦ Check the power cable.

To ensure your TV turns on properly, first, check that the power cord is securely plugged into both the TV and the wall outlet.

If the cord appears loose or damaged, it may not provide sufficient power to the TV. In this case, unplug the cable from the TV and wall outlet, then plug it back in firmly.

♦ Check the power strip.

If the power cord is securely plugged in, next check the power outlet to ensure that it is not controlled by a switch or timer and provides enough power to other devices.

You can test this by plugging in a lamp or another device to see if it turns on. If the outlet does not have power, connect your TV to another outlet.

♦ Check the remote control.

If you have checked that the power cord and outlet are functioning correctly, the next step is to verify that the remote control is working properly. First, ensure that the batteries are not damaged and have sufficient charge.

If the remote control has a power button, try pressing it to see if the TV will respond. If the TV does not respond, try using the power button on the TV itself to see if it will turn on.

Note: Consider replacing the batteries at this point (just to be safe)

Step 2: Troubleshoot the TV

If the power cord, power strip, and remote control are all functioning correctly, but your TV still will not turn on, there may be a problem with the TV itself. This could be due to corrupted firmware, damage to the main board, or a software glitch.

♦ power cycle your TV.

Sony TVs are prone to damage during power outages or sudden shocks. If this occurs, a power cycle can help clear any issues from the TV’s memory without losing your downloaded content or settings. To power cycle your Sony TV, follow these steps:

  • First, unplug it from the electrical outlet.
  • Then, for about 30 seconds, press and hold the TV’s power button.
  • Wait another ten minutes without turning on the TV.
  • Replug the TV.

Now, try turning the TV on using the power button on the remote or the TV itself. If it does not work, proceed to the next step.

♦ Check the power button to see if it’s stuck or broken.

It is possible that the power button on your TV is either stuck or broken, preventing it from turning on. If the button is damaged, there is nothing you can do to fix it yourself.

However, if the button is stuck due to dirt or dust, you can take the following steps to try and unstuck it:

  • First, check to see if the button is physically stuck. If it is, try gently pushing it in and out to see if it will become unstuck.
  • If the button is still stuck, try using a toothpick or other small object to push it in and out carefully.

Remember to be gentle and cautious when attempting to unstuck the button, as you don’t want to cause any further damage.

♦ Update your TV’s firmware.

As mentioned earlier, If your TV’s firmware is outdated or corrupted, it may not be able to function correctly or even stop working altogether. Sony releases new monthly updates to improve its system’s performance and fix minor bugs.

However, if you update your TV, there is a chance that your problem may be fixed. To do that,

  • Download the latest firmware update for your TV model from the Sony website.
  • Right-click the downloaded firmware file, then select “Send To,” “Extract” (or “Zip“), and the extraction program loads onto the screen.
  • Connect a USB drive to your computer and copy the downloaded firmware file to the drive.
  • Click “Start,” “(My) Computer,” then right-click the removable device icon and select “Eject.” (Disconnect the USB flash drive from the USB port on the computer once the icon disappears.)
  • Now, insert the USB drive into a USB port on your TV and then power the TV on.

If your TV’s hardware is functioning properly, inserting a USB flash drive into it will initiate the transfer of data to the TV. After the data has been successfully transferred, a notification will appear on the screen instructing you to remove the flash drive from the TV.

♦ Factory reset your TV

A factory reset is always recommended to fix any internal software-related error. There are two methods to do that, but we will use the manual method as we cannot access the TV’s settings.

Remember that this will erase everything, including your data and settings.

Here’s how to do that:

  • First, unplug the TV from the power outlet.
  • While the TV is unplugged, locate the “Power” and “Volume Down (-)” buttons on your TV and then press and hold both of them.
  • At the same time while these buttons are pressed, replug your TV back in a power outlet.

Warning: Do not release the power and volume down buttons on the TV until it is plugged into the power outlet. Otherwise, it will not get reset correctly.

Continue holding down the power and volume buttons until the LED light on the device changes color. This can either be green or white, depending on the model you are using. The length of time that you will need to wait for the reset to fully complete can vary, with some models taking anywhere from 15 to 60 seconds.

However, once the LED light has changed color, you can release the buttons, as this indicates that the reset has been successfully completed.

Step 3: Nothing has worked so far. What next?

If the previous methods did not work and your Sony TV is still not turning on, there may be another potential cause.

♦ Cool down your TV.

TVs generate a lot of heat, mainly if used for extended periods. However, it may overheat if your TV is in a small space with poor ventilation.

If the circuit board has not sustained any internal damage, the TV will not turn back on until it has cooled down. To fix this issue, allow the TV to rest overnight and clean any debris from the surrounding vents.

♦ Check the TV’s backlight.

It’s also possible that your TV’s backlight is burned out due to a power outage or bad electric flow. Turn on your TV and hold a flashlight near the screen to check if this is the issue.

When you flash the light, carefully observe whether there is any image on the screen. If you see a faint picture, the backlight must be replaced.

♦ Contact a repairer

If the backlight of your TV is functioning properly, it is possible that there is an issue with one of the internal components of the TV. If you are not skilled at DIY repairs, it is best to contact a professional repairer to diagnose and fix the issue.

Attempting to repair the TV yourself without the proper knowledge and expertise could potentially cause further damage. A professional repairer will have the necessary tools and experience to properly diagnose and fix any issues with your TV.

To wrap up, if your Sony TV isn’t turning on, some possible solutions are checking the power cord, unplugging and plugging the TV back in, using a different power outlet, and checking for a faulty circuit board. If these steps don’t work, it may be best to contact a TV repair technician.
