My all-in-one screen started having some issues on left side a couple of months ago like images were burning into screen. As of yesterday, the screen is now putting on quite a light show. Crazy flashing lights, black screen, green screen, all over the board. Nothing even resembling a usable computer screen as I can't do anything at all. Options? Worst case is I'd like to get to my files on the hard drive which I'm not sure I can do. Best case is a fixed display. I'll take anything in between.
Welcome to HP Forums, this is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂
I understand your computer is having a party, causing the flashy & crazy lights (having display quality issues),
I'm not parties but since you want to end it, I'll join your cause 😉
That said, to provide you with an accurate solution, I'll need a few more details:
What did the party begun? when was the last time it worked without the crazy strobe lights?
Any hardware or software changes that might have contributed towards the party?
In the meantime, let's try these steps here:
Perform a Hard reset on the PC:
Turn off the computer.
Disconnect all peripheral devices and remove all USB devices and media cards.
Disconnect the AC power adapter.
Press and hold the power button for at least 15 seconds.
Reconnect the AC power adapter.
Turn on the computer.
In order to isolate the issue, I would recommend you to boot the computer into BIOS and check if the screen flicker, if the screen flickers as it's outside of windows, I would suggest this to be a hardware failure.
If the screen stays fine, then I would suggest you perform a Bios update as well as graphic card update, from the support website, using this link.
Please respond to this post with the result of your troubleshooting. I look forward to hearing from you.
