Lg tv: Lg C1 randomly turned off.

Hey, I have a lg c1 oled tv. I turned it on it was fine for like 10 seconds. Then completely shut off. The screen is completely black. And the standby light is red/on. I’ve tried power cycling it and resetting. The only feedback I get is I can hear the psu clicking a couple times. And sometimes a lines of an image on the screen. Any ideas?

Lg tv: Lg tv Horizontal black stripes after replacement work

Thu, 16 Oct 2025 10:40:15 -0700

Hi everyone,

I have a LG 49LF550T

The TV was recently repaired for Backlight and power board replacement.

After getting it back, I noticed one or more horizontal black stripes across the screen that were not there before the repair.

The stripes are constant (don’t flicker) and appear on all sources (HDMI, TV menu, etc.), so it seems like a panel or connection issue, not software.

I’ve attached photos showing the lines.

From what I’ve read, this might be a loose ribbon / T-Con connection or a damaged TAB bond from reassembly.

Could anyone confirm what this looks like, and whether it’s fixable or means the panel’s damaged?

Also, would it make sense to take it back to the same repair shop and ask them to recheck the ribbon/T-Con connection?

Any advice would be appreciated - thank you

Hello everyone,

I’ve been experiencing an issue with my LG TV since today. As you can see in the picture, the entire screen is covered with horizontal black lines.

Could you please help me understand if there’s a way to fix it, perhaps by replacing some hardware components?

Thanks for any help!

Lg tv: Horizontal flickering lines at bottom of display

Sun, 05 Oct 2025 09:01:06 -0700

Hello! Our LG TV has flickering lines at the bottom

These lines only appear after the TV has been on for 10 minutes or so.

This occurs with all ports, different HDMIs, streaming services and so on

Interestingly enough, when the TV was off for a few months, the lines disappeared completely and only came back after a few weeks
