Laptop Display No Longer Working

Hi valley_girl1919,

I‘d suggest that you run the diagnostics on the laptop to check if its issue with the motherboard port or LCD cable on the system. Run the diagnostics on the computer by following the steps mentioned below and check if there is any issue with the hardware on your system.

1. Turn on or restart the computer.
2. Immediately at the Dell logo screen, starting tapping the key once a second until the One Time Boot menu appears (if the computer boots to Windows turn the computer off and try again).
3. At the One Time Boot menu, press the arrow key to highlight Diagnostics, PSA+ or Enter ePSA, then press to begin the PSA.
4. Write down any error codes listed. Reply to us with the error codes.

Hi valley_girl1919,

The display seems to be fine since you have run the LCD BIST test on the screen .You are getting the display on the monitor from the computer so the video card is also fine. It should be an issue with the port on the motherboard or the LCD assembly cable.

Please revert with the results.

Thanks a lot for your reply!

I did restart the laptop and press f12. the issue though is that when I select diagnostics, even though I hear the diagnoctics running I can not see anything, not even on my external monitor when hitting fn + f8. I hear beeps periodically and the colors pop up on the display of the laptop for the LCD BIST test. I did hear at one point what sounded like music and all three lock led lights on the laptop above the keyboard would light up when the music played and then three distinct beeps where all three of the lock lights would light up all the same time again. It's hard to explain, but I cant ever see if there is an error or not.
