AOC CQ32G2SE: Screen display shows only green

Tue, 14 Oct 2025 12:42:11 -0700

Hi there im seeking advice on an issue with a monitor i found in the trash.

Its a AOC CQ32G2SE monitor, a curvy beauty (couldnt choose this in the menu above but added it). And it only shows a vague light green image. It does this when connected to hdmi or displayport and when disconnected from anything except power, it does this aswel.

I remember having a distorted image on an old laptop and i could fix it by applying pressure on some ribbon cables running from the mobo to the display.

Do you guys think this green screen issue can be solved by opening the monitor and reseating the ribbon cables and trying to press some area's?

Thanks in advance!!

Hey,

Again, thanks for the info guys. I manager to get in. Used a plastic card and a plastic knife for children. Startend prying and twisting in the top corners.

There wasnt any cable attached to the plastic back panel as you can see in the picture. Also it doesnt look like anyone opened it before me.

Im going to further investigate the board and ribboncables tomorrow. Is it important to precicely reattach all the metallic and black stickers? Thats going to be hard.

If i plug in power and test pressing the ribbon cables, are there any component i need to avoid or else risk a shock?

Of course i wiIll keep you updated with pictures

Hey there,

I Managed to take some pictures of the main and powerboard. The latter has a bit of a darker brown area close to the biggest component on it. Cant really conclude anything on the mainboard.

Im going to reconnect everything screw the boards back, peel off the black tape and start poking the area's you told me.

PS Uploading pictures seems bugged. ill try to post the rest tomorrow.

AOC Display: The bottom of the AOC 23.8 - inch monitor displays abnormally.

As shown in the picture, no matter which image I open, there are always striped, inverted colors displayed in the 1-centimeter area at the bottom of the screen. Could you please tell me what the problem is and how to solve it?

AOC Display: AOC CQ32G1 Repair attempt #2

Wed, 20 Aug 2025 12:29:01 -0700

Hi,

I've been trying to repair my AOC CQ32G1 monitor and ran into trouble. But I'll start from the beginning.

Then the display broke it refused to turn on the display properly. I couldn't get anything to display regardless of port being used. I couldn't even get it to open the OSD, none of it. Not even the simple input selection. I decided that I didn't want to spend a lot of effort on it so I decided that I'd buy a new power board and a new mainboard on aliexpress and replace it. I did that successfully and when laying flat on my table I got my laptop to render on it through the HDMI. So I assembled it fully and brought it to my desktop for it to show the exact same symptoms. The new mainboard OSD (some Chinese stripped down version) didn't show up. After that I tried every HDMI/DP cable I could find in every combination of laptop/desktop I could think of and I could only get it to render once using HDMI, low refreshrate (75hz, not 59hz surprisingly). But it worked for such a short time it's hard for me to determine, I couldn't get that setup to work more than once. Once I switched from mirrored display to extended it just failed on me. The backlight has never failed me. It's never a black screen it's always just the LCD side of things that don't work.

I have pictures from it disassembled but mainly the old boards and screw positions. I can disassemble it for new pictures but I'd rather not touch it too much as the frame is losing integrity. All the internal cables seemed fine to me when I inspected them. I'm a little concerned about two of the the connectors. They were annoyingly firm even after I pushed the tabs in correctly.

So my question is about what's the likely culprit. Is it one of the internal cables that are broken? Is the LCD busted in some way that I don't recognize? I'd also be a huge help to get an idea of what diagnostic steps would be wise to do if I choose to open it again. I could probably measure continuity on the cables if I were to open it again. Since I replaced both boards the only original parts is the backlight+lcd, cables and the presumed circuitboard for the pushbuttons. Concerning the buttons on the display it's one of the more suspect areas because it's improperly mounted so it's bulging

please endure the dirt I'm not cleaning this broken monitor.
But it's been like that since I bought it five years ago and I rarely touch it. I didn't take a good look at it when it was disassembled.

AOC Q3279VWF: Monitor not displaying correctly.

Mon, 31 Dec 2018 08:03:45 -0700

Just picked up a 31.5 inch monitor from AOC, the Q3279VWF to be exact and there's something up with the display. It only comes on when the monitor has force being applied downward on it. For example, if I have the monitor at a 90 degree straight vertical angle, the display may flicker on and off but will remain off mostly, though if I apply light pressure to the bottom bezel of the monitor, it comes on for as long as I hold it.

Sounds to me like a lose connection or something. I'm routing the audio out through the headphone jack and even when the display goes, the audio stays, so it's not the cable. Also when the display goes, the backlight stays, so It's not that.

Any suggestions would be much appreciated.
