Chosen Solution
Customer has this xps 15 7590 with a frayed display cable with broken wires. Was turning on / off when adjusting screen angle or opening & closing. Then stopped working altogether. Nothing but black screen. Laptop is still booting and I can blindly login. Got the factory replacement and it won’t display either! I’m hoping the motherboard isn’t completely gone and there’s a protection fuse in line somewhere… Someone please save me! -John-
Hello all, the fuse didn’t have voltage on either side so the short must have gotten past it. The customer decided to buy new, and I had to return the screen because it’s so expensive, rare and doesn’t come apart so panel can’t be used elsewhere… Thanks to all that tried to help! I really appreciate the effort and the time you took sharing your skills, at least with your help the hdmi port works fine now, and it’ll make a nice mini desktop for someone who needs it.
@J.R. Asprelli To me no internal or external display means a video problem on the motherboard. Not even only a backlight problem as this wouldn’t affect an external display. The fact that it is booting means that it is passing POST so the video adapter must be communicating with the BIOS/OS but it has no output to either the display or the external display. Can you get into BIOS with a display? Asking this because the specs show that the laptop has 2 video adapters an Intel UJD 630 (integrated with CPU) and a discrete Nvidia GTX1650. It would be unusual for both to be faulty. Disconnect the HDD/SSD? from the motherboard and then check if you can get into BIOS on startup just in case “fast startup’ has been selected and it bypasses the chance to get into BIOS. if you get a display in BIOS check if you can disable the Nvidia display in BIOS at all and then see if you get a display on the screen after booting. You may have a faulty Nvidia GPU
