One common cause of this problem is an issue with the internal memory. Resetting the TV can often help to resolve this issue.
Another possible cause is overheating, which can also be remedied by resetting the TV. Finally, there may be an issue with the TV driver, which can sometimes be resolved by updating the driver or contacting the manufacturer for support.
In this post, I would cover the causes with proper troubleshooting steps to help you fix the issue with your Sansui TV.
Let’s get started!
- Sansui TVs may turn on and off immediately due to issues with internal memory, overheating, or the TV driver.
- Resetting the TV can often help to resolve the issue. If resetting the TV doesn’t work, updating the driver or contacting the manufacturer for support may be necessary.
Sansui TV Turns on then Off Immediately
If your Sansui TV turns on and off immediately, it could be due to internal memory issues which can be resolved by resetting the TV. Overheating is another possible cause, which can also be fixed by resetting the TV. If the problem persists, it could be due to a TV driver issue that requires updating.
Here are the detailed causes with ways to fix that to solve the issue of Sansui TV Turning on then Off:
#1. Overheating of Sansui TV
One of the most common reasons why your Sansui TV turns on and then off immediately is due to overheating. Your TV may be overheating because of a blocked ventilation system or a faulty cooling fan.
How to Fix Overheating of Sansui TV?
To prevent overheating, make sure that the ventilation system is not blocked. Check that there is enough space around the TV and that the air vents are not covered.
Additionally, ensure that the cooling fan is working correctly. If the fan is not working, it may need to be replaced.
#2. Faulty Power Supply
A faulty power supply can indeed cause issues with your electronic devices, including your Sansui TV. If your TV turns on and then immediately turns off, it’s worth checking the power supply as a potential culprit.
How to Fix the Problem with Faulty Power Supply?
To start, check the power cord, outlet, and surge protector to ensure they work correctly. If those components check out, it’s worth investigating the power supply itself.
One option for diagnosing a faulty power supply is to swap it out with a known good power supply. If that’s not possible, you can also get power supply testers that will test various aspects of the power supply, such as verifying that all the voltage levels are within tolerances.
There are also common causes of power supply failure to be aware of, such as power switching components (MOSFETS) that can cause failure if the heat sinking is inadequate or if the drain overvoltage, drain overcurrent, gate overvoltage, or the internal antiparallel diode is overstressed.
Proper design and the derating of components can help avoid these issues. Understanding and addressing key power supply issues can help prevent power supply failure in the first place.
#3. Problem with Sansui TV Internal Memory
Sometimes, a problem with the internal memory of your Sansui TV can cause it to turn on and then off immediately.
How to Fix Problems with Sansui TV Internal Memory?
If you’re experiencing an issue with the internal memory of your Sansui TV, causing it to turn on and off immediately, try resetting your TV to factory settings. Here’s how:
- Turn off your Sansui TV and unplug it from the power outlet.
- Press and hold the power button on the TV for 15-20 seconds.
- Release the power button and plug the TV back in.
- Turn on the TV and go through the initial setup process.
#4. Sansui TV Driver Issue Causing It to Turn On then Off Immediately
A driver issue can also cause your Sansui TV to turn on and then off immediately. Check for any software or firmware updates that may fix the issue.
How to Fix the Problem with Sansui TV Driver Issue?
If a driver issue is causing your Sansui TV to turn on and off immediately, try checking for any software or firmware updates that may fix the issue. Here’s how:
- Press the “Menu” button on your Sansui TV remote.
- Select “Settings” and then “Software Update.”
- If an update is available, follow the on-screen instructions to download and install it.
- Once the update is complete, restart your TV and check if the issue is resolved.
If the issue persists, contact Sansui customer support for further assistance.
#5. Sansui TV Infected with Virus
A virus can also cause your Sansui TV to turn on and then off immediately. Scan your TV for viruses and malware and remove any found.
How to Fix Sansui TV Infected With Virus?
To resolve any issues with your Sansui Smart TV, the first step is to disconnect any external devices that may be attached to the TV. Once disconnected, it’s recommended to format those devices and scan them using anti-virus software on your laptop or PC.
Next, perform a factory reset on your Sansui Smart TV. This will remove any additional files, including potential malware, and restore the TV to its original settings. This should resolve any issues that may have been caused by external devices or malware.
#6. An issue with the Sansui TV Hardware
If none of the above troubleshooting steps work, the issue could be with the hardware of your Sansui TV.
How to Fix the Problem with Issue With the Sansui TV Hardware?
To get started, it’s important to check the warranty status of your Sansui TV. If your TV is still under warranty, it’s recommended to register a complaint and log a ticket through Sansui’s official customer support channels. You can also reach them via their Twitter support @SansuiTV_US.
This is an advanced step, so only perform it with the help of a TV repair expert.
However, if your TV is no longer covered by warranty, it’s best to take it to a nearby repair shop for a diagnosis of the issue and an estimate for the repair cost. TV Repair expert will properly diagnose your TV’s internal circuit, main board, power supply, and panel to find out the exact issue causing your TV to turn off.
After receiving the estimate, it’s important to cross-verify it with official customer support to ensure fair pricing before proceeding with the repair.
In most cases, repairs can be done at a reasonable cost. However, if the cost of repairs is too high, it may be more practical to consider purchasing a new TV instead.
