Inspiron 7559, 2 amber, 7 white blinking LED
So as the title says, the Inspiron 7559 I am working on for my roommate is giving me the 2/7 pattern. It's a nice machine for his purposes. We got it working a few months ago with a CMOS drain, but it only worked for a short while. It sat for a bit and I have done a bunch of looking around, so I know that it means there is something wrong with the LCD screen, or maybe the cable, since the self-check test passes when I do that whole thing... All I want to know is if it is worth it try the cable replacement, or do you think that it is an issue with the mainboard and I need to maybe replace something else? I run a small computer repair shop from my house and have a lot of experience with complicated fixes, so I am prepared for things to get complicated haha but I figured I would at least ask here whether or not it's even worth it.
Also, if it's the board, are things replaceable on this motherboard, or do I basically have to replace the whole thing?

I have Dell Inspiron 7 series laptop. I had to disconnect the laptop LCD to fix the broken holds for hinges. Now that's another story.
Coming back to LCD Screen issue, I connected an external monitor using to Laptop's HDMI port. And the laptop is working fine. The power light keeps blinking the code 2 Amber 7 White, but, the laptop operation is not affected by that.
Initially, I had to go through Bios setup because I had disconnected Bios Battery, but once that was done, the laptop works fine. I have used the laptop part for sending and receiving mails, downloads and some other uses. Did not face any issues.
So, the blink code, as I think, is neither dreaded nor unworkable. It's just that one needs to get used to work with new setup. This message is being typed using the same laptop....err...Now a partial desktop.

The blinking pattern you’re observing (2 amber, 7 white) points to an LCD failure. Here are some steps to consider:
Check the Screen: Even if the screen appears to be working fine, there might be underlying issues with the LCD panel itself. Sometimes, subtle problems can cause this error code.
Reseat the LCD Cable: Open up your laptop (if you’re comfortable doing so) and reseat the LCD cable. Sometimes, loose connections can trigger false error codes.
Hold the Power Button: Try holding down the power button for about 30 seconds while the laptop is in Windows. This action can sometimes reset certain components and resolve the issue.
CMOS Battery: If the problem persists, check the CMOS battery. A dead CMOS battery can sometimes cause unexpected errors. If you need to replace it, ensure you have your Bitlocker key handy if you’re using Bitlocker authentication.
Motherboard: If none of the above steps work, it’s possible that the issue lies with the motherboard. You might need to consider replacing it.

So this issue is just straight up ignored by Dell it would seem lol How many people have had this issue on this forum alone and it just gets ignored on every post. Quality.

Fair point, but it doesn't change mine either. All I was looking for was some confirmation on a simple question: Is it doomed to a motherboard replacement? Answer: Yes, absolutely, this issue has no fix.

If the ePSA/PSA error indicates that it is a motherboard failure then, yes, you are doomed to a motherboard replacement.

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!

So i read your solution and bended the lcd before booting and then i saw that pc was booting properly in 1-3 trials which was way long as you said one in millions of trials. I then removed bezel and screws then remove the connector and lcd, then twisted one turn that white cable that connects to lcd. Reconnected the lcd and placed eveything on their places. Restarted and boom. It works pretty fine and starts everytime. This is the fix i guess for some cases.

Looks like you just saved my Dell 7000 laptop. Thank you so much. The first thing that happened was the blinking lights 2 amber 7 white but everything still worked. I plugged it in and powered off and the next time the screen was gone but I could still see it logging me in. I made sure and turned it off then long press D and power on had remarkable full screen color changes while I guess it ran diagnostics and it I got it back. Thanks again! J

Fixed the issue mine had. When replacing the bottom cover the LCD cable had been pinched and caused it to not boot with a black screen. It is 99% lcd/lcd cable related. Cheers
