LCD Screen is Black

HP Envy x360
Microsoft Windows 10 (64-bit)

I recently added an extra 8MB of RAM to my HP Envy x360, bringing it to 16 MB. When I powered it back up, the LCD screen remained black and unresponsive. I hooked the laptop up to an external monitor, and it works just fine.  That led me to believe I damaged the LCD cable when I disassembled the laptop. So, it's now a week later, and with a new cable, the LCD screen is still black and dead. I did check the on-board camera, and it still works. It has a touch-screen, and when I touch the screen, it shows nothing on the external monitor. I read all the boards about upgrading software and Bios, and did all that to no avail. I rebooted the laptop with the power cable and battery disconnected. 

I'm really leaning to the LCD being bad, but would like to know if there is a way to test it before I bite the bullet and spend the cash on a new one. Does anyone have any ideas on what I should do next? Thanks

@Raddodge,

 

Welcome to the HP Support Community!

 

I reviewed your post and I understand that you are not getting any display on the computer screen.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

As you mentioned that an external monitor works fine it confirms that the display is bad. However, I recommend you shine a torch onto the screen, as it may be the backlight/inverter. If you do see a faint image, then it’s time to take the bezel off and see if the screen is led or LCD. If its LCD then check /test the inverter.

 

Let me know how it goes and you have a great day!

Thank you for that suggestion. I shined a flashlight behind the monitor, and saw no image on the screen. Also when I go to display settings, and click on "detect" to check for other displays than the external monitor I am using, it doesn't detect another display.

How do I tell if the screen is an LCD or LED.

Thanks,

Bob

@Raddodge,

 

You can check the product specifications of your computer to know the display information or else you can help me with the product number for your computer and I will give you the display details.

The Fossette,

 

The product number of the laptop is M1V65UA#ABA. 

When I looked up the product specifications, I saw as the display, "15.6" diagonal Full HD IPS WLED-backlit touch screen (1920 x 1080)".  So it appears to be an LED screen. Is there a way to check to see if it is bad?

 

Thanks,

Bob

The Fossette,

 

I will have to either pay for phone support (no warranty), or use their chat service, which is what this is. I have two questions for you:

1. Is there a way to check my LCD Screen to verify it is in need of replacement?

2. What part number will I need to replace this specific screen?

 

Thanks,

Bob

By the way, most of the replacement screens are showing up in the description as an "LED LCD"screen.

If it helps identification, I removed the screen and took pictures:

@Raddodge,

 

I recommend you contact a local tech if you do not want to contact support. I don't have any information about the equipment used to check the display functionality.

 

Cheers!
