LG Television: Replaced 3 boards and still doesnt turn On

Fri, 19 Jun 2026 11:11:05 -0700

This is very weird to me since im not familiar to fixing thing, maybe someone can provide help.

I have this oled tv that wont turn on any more and remains on standy.

I have replaced for brand new:

Power supply board
T-com board
Main board

Issue remais. But I found a way to turn it on without screen

by disconnecting either one of these two connectors

I can hear and go to youtube by memory and play videos all good.

Which of course make me think the problem was a faulty screen.

But my question is, how cant it work even with the screen disconnected (image below), these connectors are unplugged

boards I replaced are brand new but still same issue.

In my head this doesnt make any sense at all, after replacing all and same thing, with screen disconnected

Thanks @oldturkey03.

Model is LG OLED48C1SPA.

Here is the cable I disconnect when it works

Im having trouble understanding how the oled panel can cause this if I disconnected it as image below

Does the OLED panel connects to the boards through other cables?

I have replace 3 boards and oled disconnected and it doesnt work unless I disconnect the cable in the first image above

Here is a complete picture with the 3 boards I replaced.

But the oled screen is disconnected as the second image

Lg tv: LG OLED C5 blackscreen after pannel & mobo replacement

Mon, 08 Jun 2026 02:58:41 -0700

Hello everyone, i just went got a secondhand LG OLED C5. I know it's not a good idea most of the time since it's particulary fragile. But here's the thing, the TV had black screen flashes going and finally going entierely black after a moment. The previous owner got a the support who changed the pannel AND the mainboard. And the problem reappeared after a full month of normal usability.

I got it and it worked like a charm for a day, not black flashes. And then i got one but i thought it was maybe a firmware problem since it hasn't been updated ever, and then no problem for 2 days. I kept the tv plugged but not turned on, and today when i tried to turn it on, it remain black. I still hear the LG turning on sound and turning off when i do it with my remote (turning on sound with the power button on the tv, but turn off doesn't work it seems with it).
I let it unplugged for several hours but then replugged it but still no pictures, no signs of backpannel problem since there's nothing when i put a light next to the screen. I openned the tv and everything seems connected right.
I plugged my pc to the tv, my pc detects the tv no problem but nothing on the TV. Do you guys think it's a powerboard issue ? Or is it the T-CON ? And of course do i have some chances to save the TV ?

If you need photos, don't hesitate to ask, i can take some. It'd be a lifesaver to know what's the problem, thank you in advance

It's me again, i think i may have found the culprit. Do you guys think this module is burnt ? Or ist normal that's it feels like it in some branches ?

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

Sun, 07 Jun 2026 22:43:11 -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!!!

LG UltraFine 5K: Green tint on screen

Thu, 04 Jun 2026 10:27:35 -0700

Hey ifixit community,

I have a question about a 24” LG Ultrafine 5K Monitor. The screen shows a picture, but it is equally greenish tinted, see attached photo.

I tried 2 different MacBooks and different cables. Also the screen has 2x usb-C input and it doesn’t make a difference which one I’m using.

I assume it’s a hardware defect on the mainboard, the question is if the defect allows to narrow down, where to search on the mainboard.

Do you have an idea what could possibly be the problem?

Thanks!

LG Television: My LG 86UP8050PVB has backlight&sound with no picture, intermittent

Fri, 29 May 2026 03:32:02 -0700

Hey guys, I'm new here.

my lg tv 86UP8050PVB stopped working.. it has backlight and the microcontroller seems to be working as the remote is working and sound and everything is working even when there's no backlight.

after rebooting the tv a few times, it turns on normally and everything is working great for a few minutes to an hour and then the picture is disappearing.

i have opened it and when the tv is working normally all voltages on the T-Con is OK (obviously), when there is no picture the only voltage on the T-Con is 13V (input from the main board) and all other voltages are missing..

i tried to disconnect all of the ribbon cables , one at a time and almost all the combination until only the 13V was connected but nothing seems to help.

i also reflowed the micro controller and the memory/pmic chips.

i will appreciate any help..

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?
