LED screen not lighting up on Samsung 3 series

by DaveJ1987 / January 15, 2015 10:35 PM PST

I had this laptop for a little over a year and when I turned on the laptop the other day the backlight on the screen didn't work. There was a display but it was very hard to see. I thought it could be a loose wire so I opened up the laptop and checked, and there wasn't so I thought it may be a faulty cable as it flickerd a few times when I moved it.

I replaced the cable with a new one, that did not work

I replaced the screen with a new one.. that did not work

So today I completely removed the motherboard so I could see under it and I found a small chip labeled A9NV 23 it was covered in a wax like substance. I have never spilt anything on this laptop.. I don't know what it was. I cleaned the wax off of it and I could see it wasn't completely soldered to the board. As I was gently removing the waxy stuff the chip came off of the board. I will try and add pictures to this post but I don't know if the laptop is now doomed or if and can get a replacement chip.

Any help would be appreciated

There are no chips from what I can tell.

When a chip fails today you replace the board the chip is on. Some explode over how the repair systems work today where we swap boards and parts till it works and deride all that note that. I'd ask Samsung for the service manual you know what parts are swappable next.

That's a shame the rest of the motherboard works fine. For the price of a new board I might as well buy a new laptop.
Thanks for your help

Some have an old spare display from their old desktop. They convert these into a desktop.
