Dell U2711 - Buzzing/Crackling sound at the rear of panel

post #1 of 9
Thread Starter 
Right, as I said in the title, my U2711 recently seems to have developed a buzzing/crackling sound at the top rear of the panel. It seems more to the right hand side, and the power cable is plugged in securley, so it's not that.

When I'm just browsing OCN/desktop, I can hardly hear it unless I put my ear near the back, and it's more of a pulsing buzz. When I display a dark image, such as a night scene, it becomes louder, and a constant buzz. It also feels a little hotter on the right compared to the left.

I called Dell Support, and until I get the name of the person/company who originally purchased it (I bought it secondhand - 3 months old), I can't do anything.

I've only found one other reference to this here, just wondering if any of you guys had any idea?

Thanks.

Sounds like a bearing is gone on one of your fans, or it might be your Power Supply Unit...

Could be a capacitor ready to pop?

Hmm, possibly, I'm not too sure about what exactly is inside of a monitor, but I'm sure they are there

Got in contact with the original owner and got the company details of whom he purchased it off, which is who it was registered to it seems.

Phoned Dell, after a short phone call with a polite man (see more here ), I'm getting a replacement on Wednesday in exchange for mine.

Happy customer.

You can buy the new one if you want, I can do you a deal, say, £610?

Nah, I would never sell, but here is hoping the replacement is properly calibrated with no issues.
