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

Sun, 24 May 2026 11:03:14 -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 55LW5300 tv image problem

Sun, 24 May 2026 08:03:55 -0700

I have a problem with my lg 55LW5300. The screen just randomly started having issues. It looks very similar to the image in the link below. The only difference is the first vertical strip is just normal greyed out and the second scrambles white. The rest of the image is perfectly normal. Is this a faulty T-con board?

LG UltraFine 5K: Why is my monitor rapidly flickering (like on and off) like crazy?

Tue, 05 May 2026 09:28:49 -0700

Hi, hope someone can help.

I have LG Ultrafine 22MD4KA-B monitor that I am trying to use with my MacBook Pro.

MacBook Pro is Core i9" 2.4 16" 2019 5600M

https://everymac.com/systems/apple/macbo...

At first the problem was that only in MacOS (various versions) monitor blnks like crazy. On the same machine i have BootCamp with Windows 11 and from there monitor works normaly. When i boot in MacOS it automaticly starts to blink and it then continue to blink even if i boot to Windows. Only way to stop that is to disconect monitor from power and wait couple of hours (usualy one night). Then it works normaly again but only in windows not the MacOS.

As i can recal i tried using LG application for this monitor in windows, and when i changed brightness it started with blinking. Again as i recall. At that time I did not used MacOS with this monitor so mabey the problem was already there, and then mabey it started with me and that LG app.

I tried couple of things like disabling auto brightnes, graphic switchnig, and so, but with no success. Also a lot of different USB-C and Thunderbolt cables (this model only have USB-C connection)

Also worth mentioning is that in Internet recovery and as i recall in safe mode it does not fliker (after one night without power).

As I mentioned in another post, it seamed that at some point monitor fixed it self (in windows and macos) but that did not lasted long.

I used monitor like that for a while, but now it started blinking in Windows also, and leting it without power is not working same as before. It continues to bilnk no mater what. Now i left it without power, and will leave it for a few day to see what will happen.

I asume that it is some hardware issue but not sure. I do not have multiple Macbooks to try them. If someome have some suggestion or hint it would be much appreciated. I love this exact model because of screen size and resolution...

LG Television: Replacement LED Strips Too Short?

Sun, 03 May 2026 08:16:42 -0700

First time attempt at replacing LED backlights for me. Picked up an old LG 55" tv (LG 55UM7300PUA) that has an overly blue picture. Ordered some replacement LEDs off Ebay, and got them in this week. Part number seems to match (SSC_Y19_TRIDENT_55UM73), but the eight-LED strips are only about 22" long (as in, about half the length of the tv screen).

I haven't broken open the TV yet, but before I do so, was wondering if having LED strips so short compared to the length of the TV is normal.

Also, I noticed that the markings on each strip are identical (i.e., there's no "A" or "B" strip designation). Are these strips typically interchangeable among themselves?

LG Television: Why does the red light flash and click but tv doesn't turn on?

Sat, 11 Apr 2026 13:51:21 -0700

LG - 55" Class G1 Series OLED evo 4K UHD Smart webOS TV with Gallery Design

The TV was working just fine in the morning. Went out and came home to the red light flashing and a little click but nothing. I've already tried unplugging then holding the power button for 30 seconds, taking batteries out of the remote and even leaving it unplugged overnight. Any ideas on what it could be would be greatly appreciated!!!
