Display not working
Hi all,
This laptop was dropped and the LCD shows physical damage. Upon booting I even get the 2/7 blink code, which correlates to an LDC failure. I've been using an external monitor for over a year or more, and it's just become a stationary laptop.
I'm now trying to fix this problem, so I ordered a new display assembly. It seemingly arrived DOA, as I got the same exact results as with my own. So I ordered another one... Same thing. So then I ordered the precise LCD screen that shipped with my original laptop, and not a difference it made.
What works?
- External monitor
- Touch Screen
What doesn't work?
- Laptop Display
No Events found!

Could you please post the model number of your system?
When you ordered the LCD did you order and replace the inverter board and cable. The inverter would cause no backlight but you might see a very dim screen that is a little more obvious if you shine a flashlight into the screen. Have you tried to run system diagnostics? Restart the system and at the Dell splash screen start tapping F12. Run full system diagnostics (this on the external monitor). Watch for any LCD errors.

It's a 5567 with FHD and Touch.
I have ordered, and still have in my possession, 2 entire display assemblies, and an LCD. In addition to that, I have my assembly. So all together, 3 complete display assemblies plus an LCD.
I will reboot into system diagnostics now and report back.
Thank you for your reply.
Edit: Not sure if it's relevant, but I constantly have the 2/7 light code, regardless of which LCD and display assembly I have connected.

When attempting the diagnostics test I had one of the newly ordered display assemblies connected. I used the flashlight on my phone and attempted to shine it on the screen, but I couldn't make out anything.
The test provided me with the following errors.
- Fail PSA V4304. 12 Error 2000:0415. Validate Code : 94363 Cables - Check the following cable, jumper, connection or sensor: LCD Cable;
- Fail PSA V4304. 12 Error 2000:0142. Validate Code : 87304 Hard Drive 0 - S/N 86STTUGTT, Short self test unsuccessful.

Could this possible be a BIOS issue? I know that the LCD cables are good, because this assembly in particular was double checked for quality before it was shipped.

I put my service tag into the Dell support section and updated my BIOS since mine was a couple years old... Now my laptop will turn off suddenly after maybe 30-60 seconds. Unfortunately I've created a new issue.
