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.

When I first purchased the monitor, second hand, the Power button wasn't always responsive and has never improved. Either way, the monitor's performance is effective.

Guessing I need to disassemble and clean the contacts and around the plastic buttons. Otherwise, if the PCB contacts are not restorable, I'll have to replace the PCB for the buttons.

Any thoughts, questions, comments and or suggestions?

I'll unplug it and do the power drain with the button and it comes back on, and will continue to do this about every 5-8 minutes, but always comes back. Any idea what the problem could be at this point? Would it be the main logic board, like a capacitor that could be bad? I can tell it's still getting power and doing something because the computer is still seeing the monitor in the display properties, and it'll come and go as you plug and remove the hdmi cable.

I've tried the easy things, different cables, different computers, updated drivers, all with the same results. And it is plugged in to a surge strip, if that makes any difference.

Thanks for any ideas!

I've tried different power cords, different HDMI cables, but to no avail.

Do I just have a faulty monitor? Can I fix it at home or go somewhere to get it fixed?

Other than that the display seems to work fine, the image is definitely there (checked with phone flashlight), so I decided I want to try and fix it if I can.

Taking it apart was easier than I even expected. Unfortunately I couldn’t see any bad components on either of the boards (power supply and logic board, I assume), and I didn’t think to take any pictures at the time. Put it back together for now.

If anyone has experience with this model (or similar ones) and can point me to what exactly to look for that would be appreciated. I saw that other Asus models seem to have problems with the power supply? Where could I get ahold of a new one to try that out?

Edit: Took some pictures:

My Acer monitor, model KG251K, has started showing horizontal lines on the screen after a power supply failure while in use. I am tracing the problem, and how do I fix it?

I already replaced the VGA cable with a new one, but the issue is still there.

Since the green line appears during the BIOS or boot screen, I think it may not be a software problem.

How can I determine whether the issue is caused by the monitor itself, the VGA port, or the graphics output of my computer?

Unfortunately, I don't have another monitor or computer available for testing.

Any troubleshooting advice would be appreciated. Thank you.

What is the cause for this?

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