I've got a question about a < 2-year-old laptop I'm working to fix. It's screen seems dead. I've checked the obvious things, like operating system screen settings and brightness. And the user says the screen just went blank one day. So I'm guessing the display was either defective or was damaged by someone.
Here's my question though. I can't get any video signal from the HDMI port, but I can run a monitor fine from the laptop's VGA port. Could this have any diagnostic implications. The more I think about it the more it seems like the HDMI port must be bad. Because doesn't the graphics card simply convert the digital signal into analogue for the VGA port? So in other words, no, the fact that I can not run a monitor off the HDMI port probably has nothing to do with the laptop's display not working?
Any advice on this would be appreciated. I plan to order a new display and install it myself. I've studied the manual for this laptop and watched a Youtube video of someone installing this display. I think I can handle it. I've already taken it apart half way just to check connections and for any other obvious problems.
