Re: Need help finding LED backlight fuse [PICS]
New screen cable did not work either. Going to have to get a replacement laptop. Since I am, I will reflow this board in to the abyss!!

Re: Need help finding LED backlight fuse [PICS]
The LCD is ok I ordered a replacement to double check and it also had the same problem. Any chance the LCD cable can be causing this? My multimeter has gone caput at the moment and have ordered a new one. Will test the pins when it is here .

Re: Need help finding LED backlight fuse [PICS]
Just an update, I purchased a new LCD just to make sure it wasn't that. Unfortunately the new LCD shows no back light either. Definitely a problem on the motherboard I guess. Looks like I will have to fork out for a replacement laptop this time .

Hi, have attached some photos to this. There was a 0 component there which I tried to jump to see if it makes a difference, but no luck....Last edited by gridl0ck; 01-02-2014, 06:51 PM.

Re: Need help finding LED backlight fuse [PICS]
Sorry should have been more clear. I have the same issue as OP. The motherboard is from an Asus X53e model but the main board has listed on it K53SD rev 2.3. I dismantled the laptop to service he charging port. I did not need to replace the port as it had only become loose from its pad on the main board. I used a soldering iron to re-establish connection between the legs and board.
After that I proceeded to put the laptop back together when I thought I would double check everything. I connected the keyboard, screen...

Re: Need help finding LED backlight fuse [PICS]
Hello, I have the same problem. I changed the charging port and the screen now has no back light. Does anyone have a solution for this yet? Seems this is the only thread on the net with any decent info about this problem. Hope someone did find a fuse/resistor which is responsible for it.
Thank you.
