Re: Lenovo E520 Backlight Problem..

Thanks again trebo, I removed the blown fuse and soldered in a small length of jumper wire. It was a bit of a battle, due to the size of the fuse and my relatively huge soldering iron tip (maybe time to spend some £££) but managed it in the end.

Now I'm glad to report the laptop is working once again.

I will give it a go and report back.

Thanks again.

Long time lurker, first time poster! I'm a bit of an electronics tinkerer, will always have a go at repairing things.
