Got annoying horizontal lines on your LG
0:02
TV screen? Don't worry, you're not alone
0:04
and you don't need to call a technician
0:06
just yet. In this video, I'll show you
0:08
step by step how to fix it yourself with
0:10
simple solutions made just for LG TVs.
0:13
Whether it's a quick glitch or something
0:15
a little deeper, we'll walk through it
0:16
together. If this helps, give it a
0:18
thumbs up and subscribe for more easy
0:20
tech fixes. And if you find a solution
0:22
that works for you, drop it in the
0:24
comments. It might just help someone
0:26
else, too. Let's start with the first
0:28
and often most effective method. Power
0:30
cycling your TV. First, turn off your LG
0:34
TV and unplug it completely from the
0:36
power outlet. Don't just flip the power
0:38
strip. Remove the plug. Then go to the
0:40
TV itself, not the remote, and press and
0:43
hold the physical power button for at
0:45
least 15 seconds. This clears out
0:47
residual power from the internal
0:49
components and can reset temporary
0:51
glitches. After that, leave the TV
0:53
unplugged for about 30 minutes to allow
0:55
it to fully discharge. Once the time's
0:58
up, plug it back in and power it on.

You'd be surprised how often this one
1:02
simple trick can clear up those
1:04
horizontal lines. Next, turn off your TV
1:07
again and disconnect all HDMI and other
1:09
external cables. Take a good look at
1:11
those cables. Are any of them frayed,
1:14
bent, or loose? Damaged cables can
1:16
absolutely cause screen issues. If
1:18
you've got a can of compressed air, now
1:20
is a great time to gently clean out the
1:22
HDMI ports to make sure there's no dust
1:24
or debris causing a poor connection.
1:27
After cleaning, reinsert the cables
1:29
firmly, and if possible, try using a
1:31
different HDMI port. Still seeing lines?
1:35
Switch to a different device like a game
1:37
console or Blu-ray player to see if the
1:38
issue is with the TV or just one of your
1:40
inputs. Now, check your environment.
1:44
Sometimes nearby electronics like Wi-Fi
1:46
routers, Bluetooth speakers, or even
1:48
microwave ovens can interfere with your
1:50
screen. Move any devices placed close to
1:52
your TV a little farther away and see if
1:55
that makes a difference. It's a small
1:56
tweak that can sometimes have a big
1:58
effect. If the lines are still there,
2:01
it's time to run a picture test. So,
2:03
just go into your TV settings menu, head
2:05
over to all settings, then support, and
2:08
select picture test. If the horizontal
2:10
lines appear during this test, it likely
2:12
means the issue lies within the TV
2:14
itself. But if they don't, the problem
2:16
is probably with a connected device or
2:17
cable. After that, make sure your
2:20
software is up to date. Open your
2:22
settings again, go to all settings, then
2:24
support, and tap on software update. If
2:26
an update is available, install it.
2:29
Also, make sure the auto update option
2:31
is enabled so your TV stays updated
2:33
moving forward. For those of you using
2:35
an LG OLED TV, go to all settings,
2:38
choose picture, then OLED panel
2:40
settings, and run the pixel refresher
2:42
feature once. Don't overuse it. Once is
2:44
enough. If your TV isn't OLED, just skip
2:47
this step and head to the next tip. Try
2:49
resetting your picture settings. Go to
2:51
the picture section and select picture
2:53
reset. This will revert your settings to
2:55
the factory defaults, which can be
2:57
especially helpful if the issue started
2:59
after tweaking brightness, contrast, or
3:02
advanced settings. Also, make sure that
3:04
the energy saving mode is turned off. Go
3:06
back to the picture settings, find
3:08
energy saving, and set it to off. This
3:10
mode can sometimes cause display
3:12
inconsistencies, especially in low light
3:14
scenes. If all else fails, try a full
3:17
factory reset. Go to general in your
3:19
settings and choose reset to initial
3:20
settings. Be aware this will erase all
3:23
your apps, accounts, and settings. So,
3:25
use it as a last resort, but it can
3:27
often be the most effective fix when
3:28
everything else fails.
3:30
And that's a wrap on fixing those
3:32
annoying horizontal lines on your LG TV.
3:35
