What is causing my fuzzy/vibrating computer screen?

Could a missing bezel screw be what's causing my laptop screen to not work?

  • I have a Compaq Presario (Don't remember the exact model number) After a year+ or working delightfully, the screen started to flicker when I'd move it and give me a black, white, or striped screen at certain angles. I was told it's probably a wire in the screen and no one would fix it. I also have a problem with the battery (it won't always charge and sometimes the computer won't turn on all the way, and I'd have to hold down the power button to turn it on as opposed to just hit it once) but that doesn't really bother me as much as the fact that I can't see anything on the screen. Well, anyways, a few weeks ago I noticed for the first time that one of the bezel screws in the corner was loose, and then my screen just stopped working completely. I can hear it turn on and if I type in my password I hear the tone it makes when it goes to my desktop screen, but the screen is completely black. Then I noticed the screw was missing completely and I have no idea where it went. Could the missing screw be the problem or is it definitely something inside the screen? I would really like to not replace my entire screen if I can help it.

    No. A missing screw is like a missing breadcrumb- The whole sandwich is still there. You screen's wire that connects to the motherboard disconnected?- Highly unlikely. Your GPU just got moved- more likely.

No, it is highly unlikely that the missing screw has anything to do with your screen not working. What usually causes this on HP laptops is that the connector on the end of your screen's data cable flexes and wears out the connection on your motherboard. Eventually the wires on the motherboard's connector crack and the situation you're describing occurs. Someone skilled with a soldering iron might be able to fix it, but usually it means that you have to replace the main board ($$$). It might be time to start looking for a replacement anyways, because the power button issue you describe is another known problem where the connector on the motherboard tends to break. It won't be long before the power button stops working at all, and resoldering two connectors would be more trouble (and money) than it's worth. Anyways, these types of issues are rampant with Dell and HP laptops. If and when you buy a new one, make sure that such problems are not present in any model that you consider purchasing. Anyways, I'm sorry that your laptop is going out on you! Good luck!
