Before we dive straight into fixing it, let us first identify the most common power supply problems on LCD TVs.

Failure to Boot or Startup

One of the more common and obvious signs that you are having a power supply failure is this.

If it’s not starting up correctly or if it’s not turning on, they’re clear signs of a damaged power supply.

Instantaneous Rebooting or Restarting

Is your Samsung TV just rebooting or restarting without any notice? Is it happening more times than how it should be?

Should it instantaneously reboot or restart, it could be a sign that the power supply is damaged.

Lockups or Freezing

Last but not least would be the freezing or locking of the television. It’s not common for a TV to freeze, crash, or lock up.

This guide will be comprehensive, tapping into all the necessary steps to fix your Samsung TV!

Step #1. Check your Remote Control.

Before you do anything, make sure that your remote control is working properly. It might be the reason why you are not seeing any display!

So, try replacing the batteries of your remote control first.

If it does, then you would want to manually restart your remote. You can do this by removing the batteries of the remote for about 20 to 30 seconds, and then press the power button.

Try it now out again to see if the television will turn on.

Step #2. Manually Restart Your Samsung TV

After that, proceed to restart your television manually by unplugging out from the socket while it’s turned on.

Do this for about 1 to 2 minutes, then plug it back into the wall outlet. Should those fail, proceed to the next step.

Step #3: Test Out Power Supply

There are two ways of testing the power supply of your television. We will tackle both of these methods so don’t worry.

You can test using a Multimeter or without a multimeter.

Testing With Multimeter

A multimeter is an instrument used to measure electrical properties, usually current, voltage, and resistance.

You will see a label of what the hot and the cold sides are. Remove the power board from the back of the television. Keep the power cord plugged into the AC outlet.

Take the digital multimeter (black lead or negative) and tap it onto a pin that says, “ground or probe.”

Then, short together the pins that have the label “PSON” and “5VSB” to tell the board to turn on all power outlets. You can use an alligator clip to short them.

While doing that, place the negative again on the ground and test each of the pins using the positive multimeter.

The goal is to make sure that all the pins correspond to the label that they have. If one or more of them have 0 or less voltage, then you know that the problem is with your board.

Testing Without Multimeter

That first method might be a bit too technical for you.

But you can test out the power supply of your television without doing that!

While having a multimeter is accurate and precise, you can perform these steps to test it out, too.

Make sure that your television is not plugged into an overloaded circuit. It will be best to connect it to a singular wall power source.

Check the power cord if it has any type of damage – nicks, slices, and cuts.

Assess the flow of AC power by connecting your TV to an independent power source. If it works and opens, then the power supply is in good condition.

Now, try inserting a lamp plug into the socket to see if there will be flickering of the LCD screen. If it does, then you are having intermittent power connections.

Step #4: Replace Bad Parts

During testing, you should already have seen where the problem is.

If it were a couple of pins on the board, replace them. If it’s the power cord or cable, use a different one with the same wattage and voltage.

If it were some parts of the board like the capacitors, purchase new ones that are compatible and replace them.

The most common problem would be capacitors that are bulged. It’s pretty obvious to determine a bulged capacitor from one that’s not.

You can purchase replacement parts of the capacitor in any electronic shop outlet near your location. The same thing goes for the pins and cables, too!

Step #5: Test It Out

After you replace the parts that are malfunctioning, don’t reassemble them yet.

The best thing to do is to perform testing first while it’s dismantled or disassembled. You will find it easier to troubleshoot more if the problem is still there.

Test out the parts you replaced using a multimeter. Alternatively, you can try to mount it to the television to see if the problem has been resolved.

If you are already too worked up about it, the next best thing to do is to contact Samsung.

Tell their technical support team or their client support about the problems you are having – tell them that it’s with the power supply.

As part of their protocol, they would perform troubleshooting steps to determine what the problem is.

Tell them that you have already done the method we outlined, but it’s still not working.
