Display: AOC 24G2SP Monitor Colored horizontal lines across the screen

Thu, 28 May 2026 04:24:24 -0700

It was just a hairline and now it is getting progressively worse.

What is the cause for this?

I have already contacted AOC support for RMA this monitor has not gone through a year yet.

I know it is difficult to fix this. What I want to figure is that whether if this line will broad to be more widely and affect my using experience. And if there will be more serious problem, such as can not light up the screen or something else? Anyone can help me? Thanks in advanced!!!

Display: Won't turn on? LG - 34UM95-P UltraWide

Fri, 22 May 2026 21:20:15 -0700

Hi,

I was wondering if someone could give me some advice? I've never fixed anything electrical and would like to give it a shot.

My LG - 34UM95-P UltraWide monitor stopped working earlier this week. It won't power on, the white LED light near the joystick at the bottom of the screen is no longer turning on - neither is the monitor itself.

I've changed the fuse in the plug, but no joy.

I've had a look online and it's taken me down a bit of rabbit hole, I found one post that suggests the issue might be related to a EEPROM chip, perhaps it needs replacing or rebooting?

Wondering what tools would be useful to get to try and fix this monitor?

The monitor is in great condition for its age - purchased in 2014 - it's not been knocked about, I think something has just burned out (I have no idea).

It might be unrelated, but worth mentioning. I mainly used it with a MacBook Pro connected via Thunderbolt port. Never had any issues with this. In the last year or so a second PC laptop has occasionally been used with the monitor. Connecting via HDMI.

Sometimes the HDMI connection seemed a bit shaky, the monitor would make a white noise/static sound almost as if it was cutting out but only for a split second. Trying other HDMI ports on the monitor didn't seem to make a difference. Unplugging the HDMI lead and giving it a blow seemed to temporarily fix it. It was very random.

The monitor finally stopped working after the PC laptop performed a windows update.

The PC laptop wouldn't connect to the monitor and the image on the laptop was jumping all over the place. The monitor was blank, no power. Not sure if this is related?

Hope someone can offer some advice.

UPDATE #1

I've managed to open the back of the monitor. Images attached.

UPDATE #2 - Saturday, May 28, 2022

Test power adapter
I've tested the power adapter, multimeter showed 19v. So at least I know that's working as expected.

Test connector
I was unable to get the red probe deep enough into the connector, so I put it on the metal coming out of the connector, see red circle below. The black probe on a screw on the board, see black circle in the image below.

The multimeter was set to resistance mode, and it beeped.

I also tried the multimeter on two other resistance settings. First on a setting of 200, the reading was 01.0 then I changed the setting to 2k, the reading was .001

Test connector with power cable

Set multimeter back to DC voltage mode, setting 20. Plugged power cable in and turned the power on. Black probe on the same screw as before, and red probe on L713 , gave me a solid reading of 19.20

AOC Display: Flickering horizontal lines on bottom 2/3 of screen

Wed, 13 May 2026 20:32:52 -0700

Bought 2 AOC 24G2 monitors during pandemic, both worked great since until a few days ago, primary screen started showing horizontal flickering lines and ghosting images.

Screenshots snipped show nothing wrong, so not GPU. Swapped cables between two monitors and secondary worked fine with primaries cabling.

Display: Sceptre monitor blue light but black screen - no image with flashlight test

Wed, 22 Apr 2026 19:10:33 -0700

My Sceptre monitor has a solid blue power LED, but the screen is completely black. I am connecting it to an HP laptop using an HDMI cable. I have already tried:

1. Hard resetting the monitor (holding power button for 30 seconds while unplugged).

2. Plugging the HDMI cable directly into the laptop instead of using a hub.

3. The flashlight test (no faint image visible).

4. Checking Windows display settings (the laptop doesn't detect the monitor).

Is there a specific internal component like a capacitor or a fuse on the main board that commonly fails in this way on Sceptre monitors?
