I've had a problem with my monitor since yesterday, my monitor is fine until I watch a film/start windows/play games pretty much anything that is dark. As soon as it gets to a dark bit in a game/film/start up everything goes much darker than normal, even white writing will look more like dark grey.I've tried reformatting my PC but the screen even went dim during the reformat. I'm pretty sure it must be my monitor, but I don't have the hardware to check so I thought I'd get some more opinions before spending on a new monitor.

Recently my 6 month old laptop, HP Envy M6-1105dx, is acting up.Specification:The screen is working fine before I left my college for spring break. I put it in my backpack then in my car trunk. It was a huge mistake because it would slide back and forward with all my other stuff. It was a 2 hour car ride. As I got home, I turned on my laptop and it was working as it powers on and the fan is spinning, but my screen is dimmed.In the picture below, I had to use a flashlight to see the screen. It does work on a external monitor.
I did research on the internet and people who had this problem said it was the inverter board and other stuff, but I don't know if that is correct.I have no laptop repair skills, but I do love to learn for future problems that might occur. Your screen is an LED Backlit version, so won't have an inverter. It's more likely that you've dislodged a connector in the screen itself, preventing the LED Array from firing up. I'm not having much success in finding a manual to help you open up the screen to look.This is the closest I could get, most screens are very similarUse guide to open up screen and look for loose connections at the base of the screen. You may have to remove the screen completely to trace the LED wires to check.

If you find nothing loose, examine the LEDs themselves for signs of damage (cloudy?)If nothing at all found, it may be a connector under the power switch assembly, and for that you would definitely need a manual to remove and inspectFound!Maintenance & Service Manual.
