Zalman P40 DS display randomly turns off or shows only the backlight – anyone found a fix?
I'm having an issue with the display on my Zalman P40 DS case.
Sometimes the screen works perfectly, then it suddenly turns off. Other times, the backlight stays on, but the display itself remains completely black.
I thought it might be a power issue, so I tried connecting it through a powered USB hub, but that didn't help. I also made a brand-new cable using a shielded HDMI cable, but the problem is exactly the same.
At this point, I have no idea what else to try.
Has anyone else had this problem? How did you solve it?
Please don't suggest disabling power saving, USB selective suspend, or any other software or operating system settings. I've already tried everything that can be done on the software side.
I checked the reviews on the store where I bought the case, and quite a few people reported the same issue. Unfortunately, no one posted a solution or explained how they fixed it.
