Hi

I have a samsung V25 laptop that has the following problem:

On start up there is no bright screen display I can vaguely see the samsung logo come up on the screen, and then i can make out windows is loading but there is no light in the screen at all.  from what i have read this appears to be a common fault with these machines, I have opened the machine and checked for loose connections to the motherbaord and the inverter -everthing appears to be firmly connected.  apparently there should also be a backlight somewhere behind the LCD screen, but i couldn't really find anthing that looked like a light of sorts (i'm am not experianced at fault findind lcd problems-yet).  

I would be grateful for any assistance in fualt finding this problem

thanks

Hi

Thanks for your response, I have already looked at this link, is there any way I can check that the inverter is ok before I purchase the LCD cables

On that site there is mention of a fuse on the inverter, but any pics I was able to find didn't really show anything that was replacable. The cables could certainly do this also if the power isn't getting to the inverter. The backlight you mentioned is 2 tubes that are on the top and bottom edge of the lcd panel. They shine into a plexiglass pane and are polarized to shine straight out the lcd panel.
