Reasons for My Sony TV Turning on Then Off Immediately
If you are experiencing the issue of your Sony TV turning on and then off immediately, it can be frustrating. However, there are several reasons why this can happen. In this section, we will explore the possible reasons why your Sony TV is turning on then off immediately.
Overheating of Sony TV
One of the most common reasons for your Sony TV turning on and then off immediately is overheating. When your TV overheats, it automatically turns off to prevent further damage.
This can happen if the TV is placed in a location where there is not enough ventilation or if the TV’s internal fans are not working properly.
Faulty Power Supply
Another possible reason for your Sony TV turning on and then off immediately is a faulty power supply.
If the power supply is not providing enough power to the TV, it can cause the TV to turn on then off immediately. In this case, you may need to replace the power supply to fix the issue.
Problem with Sony TV Internal Memory
If there is a problem with your Sony TV’s internal memory, it can cause the TV to turn on then off immediately.
This can happen if the TV’s memory is full or if there is a problem with the TV’s firmware. In this case, you may need to reset the TV to its factory settings or update the firmware to fix the issue.
Sony Bravia TV Driver Issue Causing It to Turn on Then Off Immediately
If there is a problem with the Sony Bravia TV driver, it can cause the TV to turn on then off immediately. This can happen if the driver is outdated or if there is a problem with the TV’s software.
In this case, you may need to update the driver or reinstall the TV’s software to fix the issue. Before that if TV does not remain on, power reset it.
Sony TV Infected With Virus
If your Sony TV is infected with a virus, it can cause the TV to turn on then off immediately. This can happen if you have downloaded an infected app or if you have connected your TV to an infected device. In this case, you may need to run a virus scan on your TV or reset the TV to its factory settings to fix the issue.
An issue with the Sony TV Hardware
If there is a problem with the Sony TV hardware, it can cause the TV to turn on then off immediately. This can happen if there is a problem with the TV’s circuit board or if there is a problem with the TV’s power button. In this case, you may need to replace the faulty hardware to fix the issue.
How to Fix if Sony TV Turns On Then Off Immediately?
If your Sony TV turns on and off immediately, it can be frustrating and annoying. Here are some things you can do to fix this issue.
Turn Sony TV On and Off
The first thing you should try is turning your Sony TV off and on again. Sometimes, this simple step can fix the problem. Use your remote control to turn off your TV, wait for a few seconds, and turn it back on.
Use a Different Power Source
If your Sony TV still turns on and off immediately, try plugging it into a different power outlet. Sometimes, the power source can be an issue.
If you’re using a power strip or surge protector, try plugging your TV directly into the wall outlet.
Reseat Connections
If your Sony TV is still turning on and off immediately, check the connections. Make sure all cables are securely connected to your TV and any external devices you’re using.
If you find any loose connections, reseat them.
Clean the Vents of Your Sony Bravia TV
Sometimes, the vents of your Sony Bravia TV can become clogged with dust and debris, which can cause it to overheat and turn off. Use a soft cloth to clean the vents of your TV.
Power Reset
Perform a power reset of your Sony TV. Turn off your TV, unplug the TV power cord from the electrical outlet, and let the Bravia television remain without power for 30-40 seconds. Plug it back in and turn it on.
Manual Factory Reset
This reset step is for Google and Android TV of Sony Bravia. If you have other models, do the Power reset step on the above instead.
This reset type returns the TV to its original out-of-the-box settings and can solve more persistent issues. Before starting, keep in mind that once you complete the reset, you will have to go through the initial setup again, similarly to when you first activated the TV.
A factory data reset removes all custom settings in the TV, including Google account settings, apps, channels, and wireless network settings.
The way to perform the manual reset differs depending on the number of buttons your TV has.
- If your TV model has one button, press and hold the power button located on the TV’s bottom center or left side when viewed from the front.
- If your TV model has three buttons, including the power button and volume buttons, they are on the right or left of the back of the TV.
- If your TV model has more than three buttons, refer to the TV Startup Guide or Reference guide, accessible on your product page on the support website. Follow the instructions according to the number of buttons on your TV.

Advanced Troubleshooting of Sony TVs Internal Hardware
If you’ve tried all the basic troubleshooting steps and your Sony TV is still turning on and off immediately, it’s possible that there is a problem with the TV’s internal hardware.
This can be a more complex issue to diagnose and fix, but there are a few advanced troubleshooting steps you can try before resorting to product repair.
Note: These steps are advanced steps, so only try to do this with the help of an expert TV repair professional only. Also, please avoid these hardware-level troubleshooting steps if your Sony Tv is under warranty.
Power Supply Inspection:
The first component to check is the power supply board. Look for any visible physical damage like burnt components, bulging capacitors, or loose connections. Pay special attention to the capacitors as they are known to be a common cause of power-related issues.
Use a multimeter to check if the voltage outputs from the power supply board are within the expected range. Refer to the TV’s service manual or datasheet for the correct voltage values.
Main Board Inspection:
The main board handles various functions and processes in the TV. Inspect the main board for any visible damage, burnt areas, or loose connections.
If the TV uses an external remote control receiver board, check that as well for any damage or loose connections.
Inverter/Backlight Inspection (for LCD TVs):
If the TV is an LCD model, the inverter board controls the backlighting. Faulty inverter boards can cause immediate shutdowns. Inspect the inverter board for any visible damage or loose connections.
Check for Faulty Components:
Use a digital oscilloscope or logic analyzer to probe and analyze signals on various components to identify abnormalities.
Pay close attention to temperature-sensitive components, as overheating can lead to shutdowns.
