How do I replace my hp envy m7-k111dx the touch screen is black

[Kayla-ala]

I have a complete black screen when the computer is on. It worked one day and the next I found it like this. I have been using my computer by hooking it up to the tv with an hdmi cable and noticed my touch screen touch part works but it remains black. I have done updates and drivers. Help!!!!

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

As I understand, your notebook display does not turn on,

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

• When was the last time it worked without these issues?
• Have you made any hardware/software changes on your notebook?

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.

However, if it doesn't show up in the BIOS, it would confirm a software issue and we'll need to reinstall or update the display drivers using the Official HP Website: Click here. 

You could continue troubleshooting from this article: https://support.hp.com/in-en/document/c03518165

Step 1: Performing a hard reset

Step 3: Recovering the notebook BIOS using a key press combination
