Laptop Display No Longer Working
Hi! I have a dell latitude d830. I am having issues with the monitor display. It is not working but when i connect an external monitor it works.
but the only way the external monitor works is to select F12 right when powing on and pressing the fn key + F8
to go to the external monitor, then I select the HDD option to boot the OS and it comes up fine on the
external monitor. I ran a test by pressing the D button while powering on the laptop and colors red, grey, black
blue appears on the laptop screen. When first powering on the laptop screen it appears to show a back light, but no display. Just a dark screen with some light to it.
I don't have a warranty anymore on this laptop, so I will have to buy parts to fix it. I know I will have to call Dell, but wondered if anyone else has a pretty good idea what the issue is? It seems to me that it is the laptop screen that needs to be replaced. Anyone else have this issue?

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.

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.
I‘d suggest that you 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.
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.
