We are a repair shop having the same problem today during a a screen replacement job for a Inspiron 15' 7559. Device came in not powering on, I thought it was battery flat so I just proceeded without testing to put the new screen on. After putting the new one on it I found it was still not powering on, it stuck at a black screen and LED blinking 2 amber then 7 white as described in the heading. Therefore I put back the old screen but it was the same black screen. After some play around and switching the old & new screens, pull and putting the connector back and secure it with tape etc etc. In one of the million times I made it to boot into Windows normally, everything went fine so I put everything back with the screen on and shut down the machine. I tried to run a last test before calling the customer in, found it came back stuck at black screen again. I touched nothing at all and the machine shut down like normal, no flickering no nothing. I followed instruction found on some other threads here to long press D then power on, it ran on a self test. So I did with the old screen on, nothing happens. Then with new screen on, I could see the screen have slight color changes this time but without any back light at all. Putting the old screen back on again, this time backlight lit up but screen was badly cracked so I couldn't see anything, and after just a hard power off, it came back to the black screen again. SOOOOOOO frustrated! After looking up the fault code, the LED blink shall point to LCD problem. However the tests result switching between the old & new screens was kinda on & off, there was no solid conclusion of whats wrong also I couldn't make another successful boot into Windows. In one of the long press D self tests the new screen has lit up and it could run thru the entire self test with different solid color screens but it just wont boot into Windows, and I could not make another self test run with backlight on. I started playing around with the LCD cable, cleaned the socket and connector with alcohol and tried again, same black screen. Then I have gently twisted the cable and putting the old screen on. It booted again! So this time I have hooked up an external monitor and did the BIOS update immediately. After the BIOS update I put on the new screen very carefully and now it boots every time now. Customer has picked up the machine and both of us are happy now ;) Conclusion: I really dont know if it was the cable or BIOS update did the magic for me but I will suggest to first update the BIOS first if you are experiencing this during a LCD repair. If nothing has been replaced and it happen suddenly. The LCD cable will lead to this therefore try pulling the bezel around the LCD, unscrew the 4 screws and take the LCD out. Carefully lift the tape and use the little 'handle' to gently slide the connector out of the socket in opposite direction of the tape, then putting it back carefully. Do not touch the connector, do not bent or pull the cable by force, it is not that fragile but it only take 1 hit to kill it if you do it improperly. Good luck! Answer from phonefixhk on dell.com

If your Dell laptop shows 2 amber flashes followed by 7 white flashes, this diagnostic code indicates an LCD failure. This can occur on multiple Dell models, not just one specific system. What Does This Error Mean? The LCD panel may be defective. The LCD cable could be loose or damaged. In rare cases, the issue could be with the motherboard’s display circuit. Troubleshooting Steps Perform a Hard Reset Unplug the power adapter and remove the battery (if removable). Disconnect all external devices. Hold the power button for 15–20 seconds to drain residual power. Reconnect the battery and AC adapter, then try powering on. Run the LCD Built-In Self-Test (BIST) With the system off, hold down the D key and press the power button. The screen should cycle through colors (white, red, green, blue, black). If the test fails or doesn’t run, the LCD panel may be defective. Test with an External Monitor Connect an external display via HDMI or DisplayPort. Press F8 (or the appropriate key) to switch displays. If the external monitor works fine, the issue is likely with the LCD or its cable. Reseat the LCD Cable If you’re comfortable opening the system: Power off and unplug the device. Remove the base cover and locate the LCD cable. Disconnect and reconnect it securely. Refer to your system’s service manual for detailed steps. Update Video Drivers If the LCD works intermittently, update your graphics drivers from Dell Support. Next Steps – If none of the above steps worked: If under warranty: Click the Get Help Now button at the bottom-right corner of this page to chat with Dell Tech Support. If out of warranty:The LCD panel or cable may need replacement. If the issue persists even after reseating, the motherboard could be the cause. You can contact Dell Tech Support for a service quotation or reach out to a trusted technician for a hands-on diagnosis.

r/Dell on Reddit: Dell XPS 15 9570 - Front LED Blinking 2 Amber and 7 White Flashes
June 15, 2019 -
Hi guys, I had a quick question that was giving me quite a bit of headache recently.
So, my XPS 15 is hooked up to an external monitor (stays hooked up to most of the time unless I need to take it out).
However, whenever I start up my XPS, the backlight keyboard turns on, but my screen on the XPS 15 stays black and then I see all my startup information and sign in information on my external monitor. All the while the front led is blinking 2 amber flashes and 7 white ones. I've tried to turn on my XPS without connecting the external monitor but then I see nothing at all, it stays black and the front LED continues to blink. I've searched the front LED codes and it seems to be an LCD failure but I m not sure how to exactly fix this.
It's very frustrating, because it seemed to have fixed itself a while back, but now it's happening again :(
Any help is appreciated, thanks!!

Hi,
You can try initiating the system diagnostics by following the steps in this link below: https://dell.to/2WHTOmB Let us know if you are able to initiate the test. Also, you can try to run a system LCD test as well to check if the LCD is working fine. LCD BIST: https://dell.to/2WK6rxB Try moving the system LCD to and fro gently to check if there are any changes. SK

r/Dell on Reddit: Help - 2 Orange, 7 White LED Blinking on XPS 15 9500
October 1, 2021 -
Hi everybody, I bought my XPS 15 9500 this summer and damaged the screen about a month ago for college. I bought a replacement from a non-dell computer repair shop and it worked fine for a week. Earlier tonight, I try to turn on the lap top, the keyboard LED light turns on and the screen stays black, while the LED light below the Touuchpad blinks 2 orange and 7 white. External Display works fine, and the display menu in settings don't even show my laptop screen. I look around on google a little bit, some say i need to get the screen replaced, some say I need to get an entirely new motherboard. Is there any troubleshooting I can do before I return it to the shop? I really need this machine for school work. A million thanks.

2 Amber 7 White - Display Issue. To check if the screen is working run the LCD Bist Test. Press and hold the D key and then press the power button. The display panel begins to display a solid color, or cycling through different colors. If you are not able to see the different colors on the display, than you had an issue with the display and you need to replace it.
