HP envy x360 Screen jittery and going black then coming back.

[Squanchy]

I have a HP ENVY X360 that works fine most of the time. Sometimes, it will get really jittery like the screen is pixelated and it will flicker all the way blacked out and stay blacked out on screen, then it will come back. Ive already done all I could do and even taken it to a shop to be diagnosed. Still not fixed.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• When was the last time it worked without these issues?
• Have you updated Graphics and Chipset drivers?
• Have you checked the display on an external monitor?

Let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.
