hp g62 is showing black screen

[gennacarogna]

Hi all, my hp g62 is showing black screen. Connecting it to an external monitor works. I tried the panel and the flat on another motherboard and it works. I would like to know which component is causing this malfunction. Thank you all.

Probably fuse or an filter is blown.
