Hi! Did you find the fuse for the backlight?

Re: Need help finding LED backlight fuse [PICS]

Thanks for the super quick reply. I'll let you know how it goes!!
This is such a huge learning experience for me, I'm kind of enjoying it haha.

Re: Need help finding LED backlight fuse [PICS]



I've scoured the net trying to find the schematic for the board, no luck. I was hoping for something the same quality as we found for the screen.. such a big help.

I'm assuming the issue is likely origination from this location (red line indicates position of 40-pin connector)



Couple of questions (sorry):[LIST][*]Is there anything that you think I should test?[*]Is it safe to poke around for voltage? can it cause damage?[*]When testing for voltage on pins 38-40 we used the same...

There's nothing on the led power input on pins 38,39,40. 36 (led enable input) registers 0.56v

Re: Need help finding LED backlight fuse [PICS]



Here is the very detailed spec sheet. From the block diagram it looks like the connector receives the 3.3v for the screen and a separate 7-21v for the led driver. However on the pinout of the connector I'm only seeing 3.3v

Edit: The led power input was on the next page.

Hey bubm, I got 3.384v on both the input/output of the mosfet and the both sides of the inductor. Any ideas?

Re: Need help finding LED backlight fuse [PICS]

Am I testing with the computer on?

Re: Need help finding LED backlight fuse [PICS]



Thanks for the reply. I just want to confirm the pins I'm supposed to test. 1/2 on the input and 6/7 on the output? What should I be testing for?...

I have an asus k53 series laptop. I cracked the lcd so I ordered a replacement from laptopscreens.com HOWEVER it was not a direct replacement. I found a slightly different asus laptop with the same screen specs (size, led, 40 pin, connector location) except for a 1080p resolution :P. After installing the screen and turning on the computer it looked like the connector wasn't on right (weird tint, etc). So I took the laptop apart again but this time I decided to test the screen before reassembly so to not have to tear it down again if it wasn't right. When I turned the computer on it still wasn't...
