Imagine settling in for a perfect movie
0:02
night. Blanket ready, snacks lined up,
0:04
only for your LG TV to ruin the vibe
0:06
with a parade of vertical lines across
0:08
the screen. Frustrating, right? You
0:09
might think it's game over and time for
0:11
an expensive repair. But in most cases,
0:13
it's actually an easy fix you can do
0:15
yourself. No fancy tools or tech skills
0:17
required. In this video, I'll show you
0:19
step-by-step solutions that have helped
0:21
countless people. And the quickest one
0:23
is near the end, so stick around. And if
0:25
this helps, give the video a like so
0:27
YouTube can recommend it to others. and
0:29
subscribe for more fixes you can do at
0:31
home. Let's start simple with a power
0:32
cycle. Turn your LG TV off. Unplug it
0:35
from the wall. Then find the physical
0:36
power button on the TV, not the remote,
0:38
and press and hold it for about 30
0:40
seconds. After that, keep the TV
0:42
unplugged for at least a full minute.
0:44
This drains any leftover power and can
0:46
reset internal components. Once done,
0:48
plug it back in, power it on, and check
0:50
if the lines are gone. If they are,
0:52
you're done. If not, no worries. There's
0:54
more we can try. Next, check your HDMI
0:56
cables. Unplug all of them and take a
0:58
close look for signs of wear, bends, or
1:01
rust on the connectors. If you have a
1:03
spare cable you know works well, swap it
1:05
in and use a different HDMI port on the
1:08
TV. Make sure the cable clicks in
1:10
securely. With the TV off, you can also
1:12
gently press around the HDMI port area
1:14
in case a loose connection needs to
1:16
settle back in place. Then turn the TV
1:18
back on and see if there's any
1:20
improvement. If not, on to the next
1:22
step. Try running a screen self
1:24
diagnosis or picture test using your
1:26
remote. Press the settings button. Go to
1:28
all settings, then support, and select
1:30
screen self diagnosis or picture test.
1:32
Watch closely during the test. If the
1:34
vertical lines show up, the issue is
1:36
inside the TV. If they disappear, then
1:38
it's likely caused by one of your
1:39
connected devices or cables. For LG OLED
1:42
owners, pixel cleaning can be a
1:44
lifesaver. Press the settings button, go
1:46
to all settings, then general, select
1:48
OLED care, OLED panel care, and choose
1:50
pixel cleaning. Hit start now and let it
1:52
run. This may take up to an hour and the
1:54
TV will turn off during the process.
1:56
Don't interrupt it. When it's done, turn
1:58
your TV back on and see if the issue has
2:00
cleared up. Now, let's check for a
2:01
software update. Grab your remote, press
2:03
settings, go to all settings, then
2:05
support, and select software update.
2:07
Choose check for updates, and if one's
2:09
available, install it fully. Updates
2:12
often fix display glitches and improve
2:14
performance. If the update doesn't help,
2:16
then it's time for the step that
2:17
sometimes fixes things instantly. The
2:19
fastest fix for some people is a full
2:21
factory reset. With your remote, press
2:23
settings. Go to all settings, then
2:25
general, and select system. Choose reset
2:27
to initial settings. It may ask for a
2:29
pin. By default, it's often 000000 or 1
2:33
2 3 4. Confirm and let the TV restart.
2:36
This will erase your apps and settings,
2:37
so you'll need to set everything up
2:39
again, but it can clear stubborn issues
2:41
for good. And that's it. You've now
2:42
tried every major fix for vertical lines
2:44
on an LG TV without opening it up or
2:47
spending money on repairs. Which of
2:49
these worked for you? Let me know in the
2:51
comments. I read everyone and I'd love
2:52
to know what helped. If this video saved
2:54
you time and frustration, give it a
2:56
thumbs up so YouTube can recommend it to
2:58
others. And don't forget to subscribe
