Samsung Un40h5203af Keeps Turning on and Off Continuously

According to some recent reports users have been encountering issues with their Samsung TV where it doesn't turn on and flickers the red light for some time. This issue is usually caused by a bad power supply but it can also occur in some cases due to a glitched HDMI link.

Samsung TV Won't Turn on issue.

What Prevents the Samsung TV from Turning on?

• Bad Power Supply:In some cases, the TV might have shorted its power supply due to an excessive inflow of electric current. This might have damaged either the whole power supply or some components on it such as capacitors, transistors, etc. This is a fairly common occurrence with many electric components because a power surge can seriously put a strain on the efficiency and the restraint of the components.
• Incorrect Launch Configurations:It is also possible that the launch configurations of the TV might have been corrupted due to which it is facing this issue while trying to start up. Launch configurations are stored by the television to decrease the startup time and save certain information while the TV is being shut down. However, if corrupted, it can prevent it from being able to startup altogether. This can also sometimes cause an issue where the TV doesn't connect to Wifi.
• HDMI Glitch:In some cases, it was observed thadddddt the Samsung TV was facing issues with the startup because the user was previously using a PS4 or an Xbox with it. After using the console, you might have turned it off directly without switching the HDMI source and now the console might be preventing the TV from turning on.
• Surge Protector:If you are using a surge protector device with the TV and it isn't connected directly into the power outlet, the issue might be with the surge protector. Because, in some cases, the surge protector might have worn out over time and it might not be supplying enough voltage to the TV for it to turn on.
• Source Selection:In some cases, the correct source might not be selected from the TV due to which it is facing issues while launching. This is a fairly common mistake that most users make and it prevents the TV from turning on because it can't receive the signal correctly from the source.

1. Identifying the issue

It is very important that first, we try to identify the issue and isolate the reason behind its occurrence. For this, we will be trying some basic checks to uncover whether the issue is with the hardware or the software of the television. For that:

1. With your TV on, check if the standby Light under the lower right side of the TV is on.

4. Also, make sure that the screen is being powered by tapping your finger lightly on the screen.
5. If the screen blinks it means that the screen is also functioning properly.
6. If the screen doesn't blink or the LED doesn't turn off it means that either there is an issue with your remote, the power supply or the screen is faulty. There is also a possibility that you are experiencing a black screen on the Samsung TV.

2. Powercycle the TV

In some cases, corrupted launch configurations can prevent the TV from being able to power on correctly. Therefore, in this step, we will be power-cycling the TV to completely get rid of the launch configurations which will be regenerated by the TV automatically. For that:

1. Unplug the TV completely from power and remove the power cable from the wall outlet.

2. Press and hold the "Power On" button on the TV for at least 15 seconds.
3. Plug the TV back in and power it on.
4. Check to see if the issue persists after turning on your TV.

3. Unplugging Extras

It is also possible that the HDMI source selection on your TV has been glitched due to which it is facing problems while turning on. Therefore, it is recommended to unplug any devices that you have plugged into your TV's HDMI slots. Be it your PS4, Xbox, cable box or any other device. Once unplugged, launch the TV and check to see if it launched correctly. If it does, change its source to HDMI 1 and connect the extra console in the HDMI 2 slot. After that, you can select HDMI 2 to go into the console's view and remember to change back to HDMI 1 before turning off the TV.
