Sony TV Turns On And Off Repeatedly [Causes & Solution]

Have you tried to expand your TV series collection and at the same time experienced your Sony TV coming on and off by itself? 

 

How do you feel about this? I don’t think it is a good encounter at all. This can be embarrassing and annoying at the same time. 

 

In this article, we will address such problems and provide insights and personal experiences to make the conflict more humorous.

Understanding the Problem: Why Is Your Sony TV Turning On and Off?

But first, it’s always best to examine the factors that could trigger the turn-off and on behavior from a Sony TV. 

One of the more common problems that make a TV repeatedly click on and off includes:

Power Supply Problems

A power supply control board is foremost on the list of reasons why television could malfunction.

 If the Power Supply Unit (PSU) is not operating well, the chances are that the television may turn on and off due to power cuts.

Problems with the remote control

Another reason the television may keep clicking on and off is if the remote control has been broken and therefore keeps sending signals for the television to power on or off. 

This could also be the case if a battery is running low or a button has jammed the remote.

Software Glitches

The TV may also be affected by persistent software glitches, which may be due to the product’s firmware or application software not being updated over some time. 

If such a situation arises and if the TV has been quite old and has not been serviced for quite a long time, there is a possibility of bugs occurring and causing endless reboots.

 

External Device Conflicts

Connected devices can also cause snags in the system. 

A defective gaming console, videogame console, or DVD player for example may keep sending signals to the TV in an attempt to turn it on whenever it is off.

Overheating

There are instances in which, due to security reasons, the TV may shut down. 

Such instances can occur if the television is extremely hot, this heat can be due to too little ventilation space, accumulation of dust or the fan not working properly.

Internal Hardware Failures

There are, however, internal hardware faults that can also cause power cycling, though they are less prominent. 

Internal hardware issues may include the motherboard being faulty or the power supply circuit being damaged.

Personal Anecdote

Some months ago my friend Mark had a similar problem with his Sony TV. 

After a long day of work, he was excited to relax and catch up with his best program, but the television kept turning on and off at will. 

He was in shock and expressed his frustrations, the device had to be replaced. 

A few tests later, he learned that the reason was that the volume button on his remote control was malfunctioning. 

Everything returned to normal after the remote was cleaned.

How to Fix Your Sony TV that Turns On and Off Repeatedly

We have now pointed out some of the most common causes of failure, let us move on to how to effectively deal with them. 

Here is a simple but effective illustrated guide to troubleshooting your Sony TV.

Step 1: Check the Power Supply

Inspect the Power Cord: The power cord is readily available for both the television and the wall socket and has not been misplaced. 

Check for damages on the power cord.

Try a Different Outlet: 

Reconnect the television to the wall socket but this time in a different electrical wall outlet.

Add a Surge Protector: 

If you do not possess a surge protector, it is capital that you get one. The TV has the tendency to go off with no notice in the case of a power surge.

Step Two: Check Remote Ownership

Take off the Batteries: 

Remove the batteries from the remote control so that every switch can be activated multiple  Times. Doing this can aid in resetting the stuck buttons.

Using No Remote: 

With no remote, switch the TV on and off using the buttons. In case, it works as it should, then the remote may be broken.

With the Batteries: 

Where the remote may appear to function, but with low signals, put in new batteries.

Step Three: Upgrade the Software

Make Sure That You Have the Latest Firmware: Access your Sony TV settings and search for either a “Software Update” or “System Update” option.

Will Download and Install: 

On the other hand, if there’s any update available, use the prompts to download and install it. Updating can take time but is necessary for the improvement of performance.

See: 

(if necessary) If the software update did not help, then turn to factory settings. Do be aware though that everything you’ve personalized will be lost.

Step 4: Remove All Connected Devices

Unplug All Devices: 

Remove any external devices including game consoles, DVD players etc from the TV set.

Performing a Soft Reset of the TV Set

Try Running the TV Alone: 

Switch on the television without plugging in any accessories. If the television works, one of the devices may be faulty.

Reconnect devices one by one and see if the problem reappears: 

In this way, you will be able to discover which device is causing the problem.

Step 5: Ensure Proper Ventilation

Examine the area around the television set: In particular, make sure that the television set is not in an enclosed area. 

This can result in the television turning itself off due to overheating.

Dust off: 

Accumulation of dust can obstruct the airflow. Cleaning the vents of the television using a piece of soft cloth or a can of compressed air helps.

Cover: 

Ensure that the television set is not on a carpet or a soft material that would prevent ventilation of the set.

Step 6: Open the back panel of the TV Set

Check for damage:

If you want, you can unplug the television and check internal parts that are burnt out or any loose wires that are disconnected from the board.

Professional Help: 

If you have some faults, or you have done all possible troubleshooting and the problem is still there, I suggest calling the Sony helpdesk or a qualified technician.

Personal Anecdote

I called an expert, finally, and he found that one of the power supply circuits was short. This got replaced and my TV has been working perfectly in the years to come.

Key Points to Remember

Check that the power supply is at all times and that it is not loose.

Mostly it is the remote control which has problems, so give it a good inspection.

If you update your TV Firm with the latest Software you can avoid having such problems.

Removing external devices may be helpful to check where the problem lies.

Your TV requires sufficient air circulation to function properly.
