Re: lenovo t430 no backlight

Hi,
I have similar issue. Blown fuse while replacing the lcd screen. I did a big mistake and measuring the lvds signals when battery was inserted (the laptop was off at that moment). I can confirm that fuse F7 is protecting the LVDS backlight psu. I can "fix" that by soldering *VERY CAREFULLY* wire over the blown fuse - note that you can use pads of surrounding capacitors to solder the wire. Also note that you need higher temperature and solid micro soldering iron, as this is Pb-free components.
Regards.
