Guys/Gals,
Screen flickered like crazy for a couple minutes, now LCD is dead. Computer starts up fine, power light, HD/fans, etc. HP Envy 15" (2015). I get nothing, not even an LCD blink on start-up. External HDMI doesn't work so I can't use that. This seemed to come on hours after a Win10 update when I was looking at some pictures on a website, then it started to flicker and act up. Can you help with next steps??
What I've done:
1) Tried another known good LCD screen that I had (old spare). It worked for a few minutes unscrewed from the case. I shut down, screwed it in the case, restarted and nothing since, even after multiple restarts and power drain. Tried wiggling the cable, doesn't seem to make a difference. Can't see an image using a flashlight either. I know this screen was working before.
2) Disassembled & Removed backup battery, reset DIMM, quadruple-checked cables and LCD cable. (fully seated). Everything looks normal inside.
3) Restarted with and w/o laptop battery multiple times
4) I just ordered a new cable to try when it arrives. But something tells me it's driver-related.
Any other thoughts, ideas? Things I can try? Is there another way to clear the bios? Or start in safe mode w/o going through the Win10 multi-step process? I'm running 'blind' here.
Thanks a million!!
