It didn't get an answer in four months and was automativally deleted and that's why you can't see it.
I can but rather than re-open it, I've reproduced it below. I can't guarantee the link to a Reddit thread is an use to you but it has to be worth a visit. The other link is also safe.
Hi Guys, My problem is similar to thread http
/www.tomsguide.com/answers/id-3206844/dell-inspir...
Context : After replacing the screen on my Dell Inspiron 7547, i'm not getting backlight, although on seeing with a flash light i can see that the display is working and also being detected via windows.I'm using an external monitor and it works fine.
Things tried without success (mean no backlight):
1. Remove battery and discharge fully.
2. Change display cables.
3. Diagnostics test at bootup (Pass)
4. Dell support assistant Graphics card test. (Pass)
5. Re-seat the ram. (Pass)
6. All hardware BIST tests. (Pass)
More details on what has been done.

I've two display cables and 've confirmed that they both work well on the new screen but without backlight.
Now i've an original replacement of the screen i.e B156HAT01.0 40 Pin
But no backlight.
My motherboard reads DA0AM6MB8E0 Rev:E
And i've also found schematics (https
/www.dropbox.com/s/l05mz9mkmgv76b6/vinafix.com_Q...) for my board. Unfortunately i don't know how to read this properly but looking back and forth the previous mentioned thread and proposed solution i'm trying to find the fuse for my board.
I've short listed few.
U23/25 Q23/25, C576/574/575, C580/C581/C579, C583 and R403.
If someone can help me read the sheet, i'd be able to solder (jump) the blown fuse and get it working.
Thanks for your time and help.
