My Lenovo All in one desktop's display is going crazy

[icon97]

I don't know what happened but a few hours ago it started with it having a green tint on the right side of the screen, and now it's just wigging out with black and pink lines flashing all over the screen on top of the green tint.

Here's what it looks like right now

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

It's not a laptop though, it's a all in one desktop. It started this yesterday completely out of nowhere, I've had it for almost 4 years now

The display on my desktop starting wigging out on me earlier out of nowhere, I've had it for 4 years now.

Here's what it's doing

Check the cable connections. make sure each end is secure. if that does not fix it the news is grim.
update
sorry an All in one? the computer is built into the monitor?
there are no external cable connections to check, you would need to disassemble the unit to even begin to diagnose what is wrong.

What would I be looking for after I disassemble it, I'm not tech savvy at all.

To OP. you have a AIO desktop, stop posting to the laptop forum
