It would be really difficult to watch movies or any type of program or news without the use of television sets. 

And with all the available brands, it can be pretty easy to choose a Sony TV since it is well known that it offers both outstanding quality and innovation. 

But Sony TVs are not all rosy as there can be multiple YVs problems. One of the common faults is the blinking red light code. 

This text focuses on the reasons behind these lights blinking, gives effective troubleshooting steps, and mentions some interesting stories that you might have gone through.

The Meaning Behind the Blinking Red Light

The Red Light Code: 

Spelt L-O-C-K-D

TVs contain quite a few LEDs that can emit red lights and one of such lights is blinking on the bottom of your new Sony TV. 

It can be disconcerting to see your Sony TV blinking red. 

You might be wondering what exactly the flashing red bulb means: the most basic answer is that it means some communication directed toward you. 

Every flashing pattern represents a whole army of different troubles ready for you to deal with each separately. 

The flashing patterns can be caused by the number of repetitions and intervals between the successive flashes.

Causes of the Blinking Red Light

Anecdote: 

Let me share with you my recollection. One summer I got home much later than usual, and after opening the door, I was horrified to notice my TV blinking. 

We had always been doing nothing but watching that same episode and it had abruptly cut off. 

I quickly composed myself and remembered placing the television set in an awkward space with no air circulation.

Problem with the Power Supply

Description: 

If the power supply is defective, it will create conditions when the delivered power is unstable — the red light blinks. This can occur because of overvoltages or age.

Anecdote: 

I have a friend who experienced the same. She had gone through a power cut that day and returned to her home, and her TV, a Sony TV for that matter, could simply not be switched on. 

The blinking light was not normal, and clearly suggested a power supply problem.

Internal Hardware Issues

Description: 

Certain internal components of the set such as motherboards or capacitors that are integrated within the TV, can also cause the red light to blink.

Anecdote: 

I myself only got to know about the TV blinking issue after my television began to blink out of nowhere. I later found out that there was a broken capacitor in my television which was causing all the trouble.I went to a local technician and found out that the internal hardware of my television had to be resolved.

Software Glitches

Description: 

To be honest, all smart TVs work on software, and Sony is not an exception. Their TVs, like many smart devices, can have bugs, and glitches, which can lead to the red light.

Anecdote: 

One time, I noticed my TV blinking after I had rearranged the furniture in my living room. Upon inspection, I found that the power cord had been pulled out slightly from the outlet.

Troubleshooting Steps for Sony TV Blinking Red Light Codes

Once you notice the blinking red light, you need to think about the appropriate response in a step-by-step manner. Here we discuss several things that you can do:

Two blinks: 

It means there is a blunder in the provision of power.

Three blinks: 

It is associated with the hardware of the television device that is housed internally.
