Question External Monitor gone Blank (gray)

[KrOo12]

Hello, I have a Dell Monitor - Gaming Curved 34" S3422DWG.

I usually have 2 laptops plugged in, I frequently jump from projecting one to the other.

Yestarday it started failing, showing a gray light, it was on, it just showed solid bright gray color. After fiddling the little menu knob for a while, it finally showed my desktop again. Then later I tried switching to the other laptop and the same happened, but this time, it never showed anything else again.

As a last test, I plugged it into a different PC, getting the same outcome. So it's not the computers, it's actually the monitor.

Anyone knows this to be a known issue? Which other tests could I do? I'm willing to open it, my guarantee has expired, so I'm ok with the risks. Any knowledge or suggestions are welcome.

no error showing on the screen such as, "no signal" or anything at all?

the fact that manipulating controls or giggling the display may have reestablished connection would lead me to believe that there is a bad connection, possibly the internal image processor not being in full contact with the screen.

if it is really out of warranty you could go ahead and carefully dismantle the screen housing without any worry and make sure all contacts are secure and there's no visible damage(burns, etc).

Hello John, no error, just simply a solid gray screen after any screen resizing.

I actually did open the screen this weekend and tried removing the humidity and dirt with an electronics cleansing spray, I double checked all the connections while reassembling it.

It came on again, and I'm actually using it right now, but something's wrong. For example, the gray screen sometimes comes on whenever I switch screens. I was also playing a game which resizes your screen when it goes into fullscreen mode and the gray screen appeared again, it seems to have something to do with the image controller, I don't even know if I could buy the component somewhere to get it fixed.
