LG Television: a red blinking light and the tv won't power on

I have the similar issue of a red blinking light and the tv won't power on. I've done all the external troubleshooting to try to get the tv to power on. My tv model number is a 55UQ7570PUJ. The brand is LG. Any help with this would be greatly appreciated! Thank you!

Here's photos of the boards in the tv.

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!!!

LG Television: Why won't my main board replacement work?

Sat, 28 Mar 2026 17:02:01 -0700

I ordered a new main board from Encompass to repair my snowy screen issue and upon installation the screen will not power up. The power light goes from constant red to off like normal but the screen will not power on. The initial symptom experienced from the old board was a static/snowy screen with functional sound and sub titles. I figured from research that the main board was bad so I order a replacement (EBT64049102). See attached photos and please advise if there is a step during the replacement process I a missing. This television is a 65UF6450UA LG 65" Smart TV.

Thanks,

Daniel

LG Television: turns on and immediatly shuts off

Fri, 27 Mar 2026 06:18:34 -0700

A few years ago it was doing the same thing and I would unplug from the back of the tv and restart and then it worked fine.

Lately though, the red light is on when I turn on with the remote there is a click, the red light turns off, the screen goes gray for a moment then you hear that click again and the red light comes back on and the screen goes black.

It's an LG plasma, 42PT350, its from 2011, maybe it's reached it's life?

LG Television: LG 55UF680T Red Light Blinks 3 Times

Thu, 26 Mar 2026 18:57:06 -0700

Have a LG 55UF680T when I turn on no Screen display just black and Red Light Blinks 3 Times. Have replaced the Power Supply also have checked the LED Backlights with tester and they light up. Does have 13.2v and 3.3v at PWR_ON. Thinking it may be the Mainboard but would anyone have more testing I could do before I get a Mainboard for it

Disconnected the LED Backlight Connector, Still getting the LED Error and no image with a torch on the Screen. Also Tested the LED Backlight with my tester and getting 169v on both sides

Disconnected the Left Tcon Cable and the Screen lights up one half of the Screen. Reconnected the Left and Disconnected the Right and again the other half of the Screen lights up. The Panel looks fine no defects. Disconnected both Tcon cable and still boots with the Red Light blinking 3 times and no Display

Any help would be great

LG TV 49SJ810V: Why is my screen intermittently flickering with horizontal lines?

Sat, 14 Mar 2026 15:48:30 -0700

TV screen has apparently normal display, interrupted every few seconds by horizontal lines https://youtu.be/CFx9Tk5bINY

Possible contributing factor is 2 year rampaging around house during lockdown, but didn’t see her do anything to the TV immediately before this started earlier today.

Have tried unplugging everything, reset to factory settings etc. Still happening so seems to be a hardware problem. No obvious damaged/loose connections inside. Any ideas on likely cause and how to proceed?
