LG Television: Why does everything have a blue tint?

Sun, 08 Dec 2024 19:40:08 -0700

I have had my LG 43UF640V 43” smart TV for 2 years and over time, the picture has become more and more tinted. Everything looks a blueish purple.

This problem occurs all the time, with my sky box, DVD player and Netflix and YouTube apps on the smart tv.

I have tried adjusting all the picture settings. I have turned the picture temperature all the way to warm and even this doesn’t help lessen the blue tint. I’ve tried everything.

What might be causing the blueish purple tint?

Any help much appreciated,

Thanks.

LG Television: How do I fix dark screen but can faintly see picture when I hold light

Thu, 20 Nov 2025 23:28:22 -0700

I have LG 47LN5200-UB, has been working fine but two nights ago went to turn it on and screen is black. I can see a Faint picture if I hold a flash light up to the screen.

I have tried unplugging it, holding the power button for 10 seconds and plugging it back in. I tried switching picture settings to vivid. But did not help. Sound works fine.

What else can I try.

LG Television: LG TV - powers on, but black screen after LG logo, backlight is on

Tue, 18 Nov 2025 14:28:15 -0700

Hi guys,

A few days ago my TV screen suddenly went black and I don't quite know what to do.

Basically, if I turn it on the LG logo will appear for about a second or so and then the screen goes black. although backlight stays on. The only button on the remote that does anything is the on/off one.

Called up 2 tv repair shops and both told me almost straight away that it sounds like the panel is dead and I need to basically replace the whole screen (a $3,000 repair), which I don't quite believe.

When I took the TV off the wall and tried turning it on again a few days later - it worked fine for maybe 10 seconds and then the screen went black again.

Maybe there is a loose connection somewhere or something.

Any ideas? I hope there's something I could try before I throw it away.

The model is LG 70" UH635T, I could find it in the list so had to choose a random LG model when posting this question

Thanks!

LG Television: Left side is too dark. How to fix it?

Wed, 27 Mar 2024 22:29:18 -0700

Hello,

I got a LG 42LG5000 TV in 02/2009. In 02/2011 (just after the TV's warranty expired), when I opened the TV to watch something, I saw that the left side of TV was much more darker than the right side.

As manufacturer and repairers say "left LCD panel is gone, replacement price is much more then TV's price, so throw the TV to trash" but I'm not convinced actually because of the following;

Till a month ago, when I shake the TV or wait a little bit, the left side was coming back to normal but in last month, it doesn't.

I'm attaching the pictures. So you can see the problem and may give some advice to me.

LG Television: LG 47LB5900-UV TV display is flashing / flickering on and off

Mon, 06 Oct 2025 07:20:25 -0700

I have a LG TV 47LB5900-UV, which is about 1.5 years old and the screen suddenly started flickering on an off. I was watching TV on it and suddenly the display just went off, the flashed on then back off. At this point the display is primarily off, but flashes on for half a second, then back off. This is happening with the initial screen, on screen menu, and with any input. I opened the back and reseated the internal cables between the 3 boards, but the issue remains. The connectors on each cable are somewhat recessed, so I am not sure of a good way to clean them.

The TV doesn't seem to be completely powering on and off, just the screen is flashing on/off. Whatever is would normally be displayed is just flashing on briefly until I turn the TV off.

Please advise how to test and further isolate to which component should be replaced.

Tcon? Power board? Main board? Cable?

LG Television: TV won’t turn on

Fri, 01 Nov 2024 19:01:05 -0700

There was a severe thunderstorm in my area a few days ago and my LG Smart tv turned off and won’t turn back on. The red light at the bottom just blinks when I try to power it back on. I’ve unplugged everything from the tv including the cable cord and power and let it sit overnight then only plugged the power cord back in and it still won’t turn back on the red light blinks non stop. Is scheduling a repair appointment best at this stage?

LG Television: Why is my 55 inch LG TV turning off by itself?

Sat, 06 Jul 2024 13:03:24 -0700

While watching tv, it will shut off by itself. I have to unplug it wait a few minutes and plug it back in again, then it works again for awhile, then shuts off again. I have no idea why. I have it plugged into a power surge protector. I was gone away on vacation for 2 weeks and it was previously working fine, until I returned home. Now it shuts off by itself.

LG Television: How Can I restore LG TV's firmware to default?

Sun, 10 May 2020 04:30:22 -0700

I have an LG 47LV5400, one of the LG 2011 models with Medialink and "Plex Client integration. This worked quite fine until I installed an update. Now my TV is unable to find the Plex server.

After an additional update, the NTFS USB hard drive won't work anymore. I formatted it to FAT32 and that won't work either ( the TV wants to format it to be used as a DVR).

I would like to know if there is a code or something that will set the TV's firmware back to default.

LG Television: Why the brightness of the display became dark?

Sat, 03 Feb 2024 19:59:45 -0700

LG 32LB5610

Suddenly TV is showing everything very dark.

It is as if you got the brightness near to zero even if you have it to 100.

Still the same after resetting it to its factory settings.

I am sure that this is a hardware problem.

Any suggestions?

LG Television: LG LED TV has backlight but no picture.

Sat, 18 Nov 2023 23:38:17 -0700

I have LG 55LA6205. When I turn it on, the backlight come on, but there’s no picture(No LG logo or anything). I checked the voltage on the Power supply, everything was normal. Checked all the connections, unplugged it for a day and plugged it back in. Nothing worked. Until I remember Sometimes I use the LG remote app on my iPhone. It has a feature to view what’s on the TV, like a second screen. So, I turn on the tv, and took a screenshot. It showed the LG no signal cube thing. So I took another one, this time I pressed the input button on the side. It showed the inputs screen. I researched before posting and couldn’t find a definite answer about this problem. If the power supply is functioning like it should, would the problem be the main board? But the main board seems to work. Or could it be the panel. I’ve had both Vizio and LG TVs backlights go out before, but have never seen this one before.

Lg smart tv: Dim grey screen, no picture, good sound.

Sun, 16 Mar 2025 13:04:50 -0700

Hello,

I have an LG 55 inch smart tv, 55UK5090PUA. The screen suddenly went from a solid picture to a dimly lit grey screen. There was no transition where it was intermittent - it just stopped displaying a picture, although when I pressed hot buttons to get to a streaming service, I could hear the sound.

After trying the reset/troubleshooting, I replaced the Main Board with the same replacement part (EBT65513202), plugged everything back in, with the same results. I guess now I have a back-up.

Does anyone have a suggestion on what I should check next (and how)? With the back off the TV, you can see the back lights on for sure, so I believe there is juice moving through the power board.

Thank You in advance,

Evan
