Why My LG TV Wont Turn On? (Easy Fixes You Should Try!)

For some reason, most LG TVs eventually experience the same issue of simply not turning on.

There are numerous cases of LG TV owners who claim to have experienced this issue – some claim to have been dealing with it for years! Fortunately, there is a simple fix on LG tv wont turn on that should fix about 80% of LG TVs that won’t turn on.

So, How To Fix LG TV That Won’t Turn On?

If Your LG TV won’t turn on, try these 6 simple solutions:

1. Examine the power cable connections.
2. Turn on the television by pressing the power button.
3. Check that the sensors are not blocked.
4. Reset the remote control.
5. Wait 2 minutes after unplugging the television.
6. Restart the television.

WHY MY LG TV WON’T TURN ON?

If your LG TV will not turn on, it must be reset. Unplug your television and wait 60 seconds. Press and hold the power button for 30 seconds while the TV is unplugged. After 60 seconds, reconnect your LG TV and it should work.

1. UNPLUG LG TV FROM WALL

While this fix sounds obvious, unplugging your LG TV from the wall socket is the most common way to get it to turn back on. The key here is to wait the entire 60 seconds. Have some patience and wait at least a minute before plugging it back in.

Find and hold the power button on your LG TV for 30 seconds while it is unplugged. Check that you’re holding the power button on your TV, not the remote!

This helps to drain any remaining power in the TV and allows it to soft reset itself. This is not the same as simply turning the remote on and off! When you plug the TV back in after 60 seconds, it should power back up without a hitch.

While this fix should work for about 80% of cases, the remaining 20% can be a bit trickier. If you’re still having trouble getting your LG TV to turn back on try the fixes detailed below.

2. REMOVE BATTERIES FROM LG REMOTE

If unplugging and replugging your TV didn’t solve the problem, try removing the batteries from your remote. Make certain that both batteries are completely removed from the remote. After removing the batteries, hold down the power button on the remote for 30 seconds.

Repeat for a total of 30 seconds! Not ten seconds, but thirty! Replace the batteries in the remote and try to turn on the TV after the full 30 seconds have passed. It should be turned back on. You might want to put in a new set of batteries during this step just to be safe!

If either of the two steps above fixes your LG TV power problem but then a few days or weeks later you run into the same issue, you’ll want to try factory resetting your TV for a more permanent solution.

3. FACTORY RESET LG TV

Click the Gear icon at the top of your remote while the TV is turned on (hopefully unplugging it or removing the remote batteries was able to temporarily power the TV). Then, on the left, select All Settings (Advanced Settings) > General > Reset to Initial Settings.

Your television will turn off and on again before displaying the initial setup screen. This will essentially return your LG TV to the settings it had on the day you bought it. That means that all account settings will be deleted, as well as any installed apps!

4. FACTORY RESET LG TV WITHOUT REMOTE

If for whatever reason you do not have access to your TV’s remote, you can still factory reset your LG TV. To do so, locate the power button on your television. Depending on the model, this may be located on the right, left, or very bottom of the device.

Press and hold the power button for about 10 seconds while the TV is turned on. If that doesn’t work, navigate to Menu > All Settings > General > Reset to Initial Settings using the TV’s joystick panel control.

There are other options if you can’t find these buttons on your TV or if it’s mounted in a confined space. To begin, consider plugging a USB keyboard directly into the back of your LG TV, which you can then use to navigate and reset your TV.

If you have an LG Smart TV, you can also download the LG ThinQ app to your smartphone. You can use your smartphone as a remote after connecting your TV to the app! Another option is to use a universal remote that you have to lie around and enter the appropriate LG code for the remote to get it to work.

You should have resolved your power issues by this point, but in case you haven’t, I’ve included some additional steps worth trying before calling it quits.

5. RESEAT POWER CORD IN BACK OF LG TV

Unplugging the power cord from the back of the TV is another simple potential solution to your power issue. Unplug it for about 60 seconds before plugging it back in.

Make sure the connection is snug when you plug it back in! You don’t want this to be loose at all – a tight connection is necessary to ensure that the TV receives consistent power. Reconnect the power cord and turn on the TV using the TV power button, not the remote! Hopefully, you’ll see the television come back to life.

6. SELECT THE CORRECT INPUT SOURCE

Because of an incorrect input source, your LG TV may not appear to turn on. For your TV to function properly, you must select the appropriate input source.

So, whether you’re using a streaming device, a DVD player, or a cable box, make sure your TV source/input matches the number of HDMI ports you’re using. In the following example, you would set the TV to “HDMI 2.” You can choose the correct input source using one of two methods:

Method 1 – Enable Input Source using a Remote Control

• Turn on your TV
• Press the Source button on your remote control
• Select the desired input mode

Method 2 – Change Input Source without Remote Control

• Turn on your TV
• Press the MENU button on the side or bottom of the TV
• Use the volume button to navigate to the source option
• Press the menu button to select the desired input source

Note: Some TVs have a source button at the back or side that you can use to select your preferred input source.

7. TRY A DIFFERENT POWER OUTLET

While this is unlikely to be the cause, if you’ve had no luck up to this point, I would try plugging your LG TV into a different power outlet in your home. We don’t always notice when an outlet has a short or a blown fuse.

If you don’t want to lug your TV around, you could simply plug another smaller appliance into the outlet you’re attempting to use for your TV. If you see that device turn on, you know that outlet is operational and that it is most likely not the source of your problem.

Again, this is unlikely to be the cause, but it is a worthwhile troubleshooting step that should be eliminated as a suspect as soon as possible.

8. BACKLIGHT IS BROKEN

If nothing has worked up to this point, it is very possible that your LG TV’s backlight is broken. To test whether or not this is the case, turn on your TV and then bring a flashlight very close to the screen.

When you flash the light, look closely to see if there is an image on the screen. If you see a picture but it’s extremely faint, it’s most likely because your TV’s backlight has failed and needs to be replaced.

9. MOTHERBOARD IS FRIED

If there was a recent lightning storm, it’s possible that your motherboard was fried. Unfortunately, the only way to be certain is to remove the back paneling from your LG TV, which will reveal a few boards – the motherboard (or “mainboard”) and the power board are the two major components.

To ensure that the problem is not with the power board, plug in your TV and turn it on, then detach the cable that connects the motherboard to the power board from the power board side. If the TV continues to light up, you know the power board is fine and you have a faulty motherboard.

Motherboards are pretty cheap to replace, just make sure you get the exact replacement by checking the numbers on the board itself. Or, if you’re not comfortable doing this yourself, go ahead and have a TV repairman assist you.

10. CHECK LG TV WARRANTY

This is always a last resort, but if you simply cannot get your LG TV to turn on, you should check to see if your TV is still under warranty.

After you describe the problem and LG determines whether or not it is covered under warranty, they will either repair or replace your TV. They even provide in-home services if this is covered by your warranty. It’s worth a try!

HOW TO FIX LG TV NOT TURNING ON RED LIGHT FLASHING?

When an LG television does not turn on but has a red light, try turning it on with the power button on the unit rather than the controller. If you turn on the television by pressing the Power button, the remote control may be defective.

If you’re confident that your remote is working properly, make sure the line of sight between the remote and the TV’s sensor isn’t obstructed. Then, using the remote control, try to turn on the television again.

If the television still does not turn on, replace all of the batteries in the remote control and repeat the process. If none of the above troubleshooting approaches turn your device on, you have two other options:

• Reset the controller manually.
• Use a remote control app to switch on the TV.

You can also turn to smartphone remote control applications compatible with LG TVs, like:

• Smartify
• Anymore
• Peel Smart
• LG TV Plus

HOW TO RESET AN LG REMOTE CONTROL?

When your television does not respond to the power controls on your remote, the issue is almost always with the controller, not the television. This is especially true if your LG device has an active LED display.

To resolve this issue, perform the following steps to reset your remote control:

1. Press and hold the Back and Home buttons for 5 seconds to unregister the remote. A red LED indicator will flash when the remote is unlinked.
2. Turn on the television by pressing the power button.
3. Connect the RF Dongle to the USB port on the TV. When you buy a dongle, it usually comes with a remote as an attachment.
4. Wait 20 seconds before proceeding.
5. To register the remote, use the scroll wheel.

If your remote control lacks a scroll wheel, reset it using the Back and Home buttons on the remote control. To reset the remote, press and hold the buttons for at least 5 seconds.

After that, review your user manual for instructions on how to repair the unit. Then, attempt to power your television using the remote before considering the controller broken.

HOW TO FIX LG TV WON’T TURN ON NO RED LIGHT?

If the status LED does not light up and the TV will not turn on, unplug and reconnect the power cable. You can then check to see if the status light is illuminated; if it isn’t, continue reading. LG recommends connecting your television to a wall outlet.

As a result, if your LG unit is connected to a power strip, consider relocating it because the strip may not provide enough power. Are you still having issues after connecting it to the wall?If this is the case, try a soft reset on your TV by unplugging it and leaving it unplugged for at least ten seconds.

If that doesn’t work, repeat the procedure but leave the device disconnected for about a day. If the problem persists, the LG television may be broken, which is frequently the result of the following mishaps:

• Outage of power
• Electricity surges
• Corrosion-prone connectors
• You can seek advice from an LG service representative on how to proceed.

HOW TO FIX LG TV HAS POWER BUT WON’T TURN ON?

If your LG television receives power but does not turn on, the power capacitors may need to be replaced. Examine the list of symptoms provided below. If your TV is experiencing any of these symptoms, your device’s capacitors must be replaced immediately:

• The LG unit freezes at the logo.
• Lines running across the screen
• The unit intermittently turns on and off.

Even if you don’t notice any of these symptoms, replacing the capacitors is the most logical solution to the power problem.

Diagnosing Worn Capacitors

The diagnosis of capacitors is straightforward. Locate the motherboard and inspect for brown capacitors after removing the back panel of your unit. A blown capacitor will also exhibit the following characteristics:

• Top is bowed
• Corrosion
• severing leads
• Brown fluid is leaking.

The following tools are required to replace the capacitors:

• Screwdriver
• Iron for soldering
• Wick for soldering
• Capacitors that work together

HOW TO REPLACE CAPACITORS IN AN LG TV?

Following that, replace the capacitors as follows:

1. Disconnect the power supply for the television from the wall outlet.
2. Remove the backplate with a screwdriver.
3. Remove the motherboard from the casing of the television.
4. Consider the polarity of the capacitor. Compare these values to the values on your replacement piece to ensure a proper fit.
5. Apply intense pressure to the capacitor’s solder joint with the tip of a hot soldering iron. Use a soldering wick if there is too much solder in the hole for your iron to penetrate.
6. Remove the wire lead from the capacitor. If the joint melts, the tip of the iron will fall through the circuit board cavity. You can then disconnect the wire lead.
7. Take note of the wire lead’s length.
8. Trim the replacement capacitor tips to the same height as the old ones.
9. Put the current capacitor leads in the holes where the old capacitor used to be.
10. Directly press the tip of the soldering iron into the backside joint of the circuit board.
11. As soon as the end of the wire lead slips through the hole, insert it into the hole.
12. Take out the iron. The solder joint will solidify and hold the replacement in place.
13. Re-run the procedure with the remaining capacitors.
