Sony TVs are renowned for their stylish designs and reliable performance, but they may occasionally experience issues.
One common cause of red light blinking on your Sony TV may be a power supply issue. It could also be related to another connected device like a USB cable or DVD player that’s having issues.
1. Check the Power Supply
A red light blinking on a Sony TV may indicate there is an issue with the device, either electrical or software related. Before calling an expert, make sure you inspect the power supply of your Sony television that is flashing red so you can resolve it yourself.
First, attempt to reset the television by unplugging it from a power outlet and pressing both “Power” and “Volume Down (-)” buttons on the remote. Hold down these buttons until you see an LED light turn green or white indicating that reset was successful.
If the red light on your Sony TV continues to blink, disconnect all devices connected and wait 5 minutes before plugging it back in again. If you can’t get the red light to stop blinking, then it may be time for a professional repairman.
Another option is to upgrade the software on your Sony TV via internet connection if it’s connected to Wi-Fi. Generally, this should take around 5-10 minutes for the software to install and stop the red light from blinking.
One of the most common causes for Sony televisions that blink red is an internal short circuit. This occurs when there is a voltage drop within its internal circuits, leading to no power output.
Most circuits comprise resistors and transistors. You can verify if there is voltage present in these circuits by measuring its reading with an analog multimeter.
You can check the voltage with an electronic voltmeter. If there is a reading above 19V, it indicates that there is an issue with one of its resistors or other electronic components on the power board of your Sony television.
An electronic voltmeter can be an efficient tool to identify the cause of a Sony television that’s flashing red, since it will show how much voltage has gone out of each resistor or other electrical component. This helps pinpoint where the issue lies so you can fix it and prevent future issues from arising.
2. Check the Power Cord
Sony televisions often display a red light when there is an issue with their power supply or main board. To resolve this, try unplugging and reconnecting the TV; usually this will force the problem to reset itself and fix itself automatically. However, if this persists, contact Sony support for assistance.
First, inspect the power cord of your Sony television to make sure it’s in working condition. In particular, look for any kinks or knots in the cable which could damage its copper wires. Furthermore, take a close look at the back power connector to confirm it’s free from corrosion, dirt and dust buildup.
Another step you should take is using a voltmeter to check if your power board is functioning properly. If the voltage readings are inconsistent, this could indicate an issue with the circuit board.
If the voltmeter indicates that your board is functioning correctly, you can proceed to the next step in this troubleshooting guide. To restart your Sony television, unplug it from its wall outlet and press and hold the power button for approximately 30 seconds on your remote control.
Once the television has been restarted, check the red light again. If it is still blinking, attempt disconnecting all devices from the television and reconnecting them one at a time.
If none of the devices connected to your TV are causing the problem, then you can begin looking into the software in your Sony television. If it has internet capability, updating its firmware through Sony’s web portal should solve it; otherwise, performing a factory reset on the device should get rid of all previous software and prevent red light blinking again.
3. Check the Connections
One of the most frequent issues that causes a Sony television to blink its red light is an intermittent connection issue. This could be something as simple as your USB cable not working or it could be something much more complex like an issue with either your main board or power board on your television set.
To check the connections on your television, you will need to turn it off and unplug it from its power supply. Doing this will allow you to determine if the issue lies within the television itself or with another device.
If the problem lies with a USB cable or any external device, disconnect it and try turning on your Sony TV again. If the light still blinks, that indicates an internal problem and you must purchase a replacement item.
You may try resetting your Sony TV to see if that solves the issue. To do this, hold down both power and volume down buttons on the remote while plugging it into a wall outlet. Continue holding these buttons until a green light illuminates, signifying that reset has been successful.
In most cases, a simple soft reset will solve your issue and have you up and running quickly. However, if the problem is more complex and requires further repair work, then calling in a technician for assistance is necessary.
The next step in checking your Sony television’s motherboard is to look for any signs of damage or components on it that need replacing. Take them out and replace them with a brand-new one to avoid future issues.
Checking for a motherboard malfunction on your television is an incredibly fast and effortless way to determine if there’s an underlying issue with the board itself. In most cases, this will cause the light to blink 11 times; thus, make sure you get this checked before looking into other hardware solutions.
If the red light blinks 11 times while using a Sony TV, it could be due to damage or corruption of the Trident IC on the motherboard. Check other components on the board to make sure there are no other damage signs and all parts are working properly.
4. Check the Software
It is imperative to regularly verify the software of your Sony device, whether you own a TV or projector. Doing this can prevent any problems caused by system errors or hardware defects.
In most cases, a simple soft reset is all that’s necessary to get your Sony device up and running again. To do this, simply power off your device for several minutes, then restart it once more.
If that doesn’t solve your problem, try resetting the firmware on your Sony TV. This should restore everything back to its original settings and should resolve any software errors causing the red light blinking issue.
However, you should be aware that this is a complex step and may take several attempts before success. Therefore, it’s wise to back up all important data before attempting this procedure.
To upgrade your TV’s firmware, press either Home or Menu on your remote. This will bring you to the settings menus for your television and usually have the option to update software located under Product Support or Contact Sony.
This process may take up to 10 minutes, so it’s wise to wait for the installation to finish before turning your Sony TV back on again. Doing so gives your device time to refresh and install any potential software updates that may be available.
Reload your Google account (if applicable) and set up network setup if your TV is internet-enabled. Furthermore, ensure the HDMI cable is plugged in securely.
If the software update doesn’t fix your issue, it may be time to contact a repair technician. They can explain why your device is showing a blinking red light and provide an estimate for any necessary repairs.
Before calling in a repair technician, try these basic troubleshooting steps first. This will help identify the issue and provide an immediate fix. If none of these work, contact Sony customer support center to discuss your concern and receive some helpful suggestions.
