m007ayon, first you want to attach an external monitor and see if what that shows. If it shows okay, you know that your GPU and video circuitry is okay. That would leave the LCD and/or backlight as a possibility. > If you have no display on an external monitor, then you have issues with either your GPU and video circuitry, or your computer just does not post (BIOS error).

okay your motherboard is a HP part number 500755-001 and listed as a 6050172227701.AO2 From your images, #3 is a VIA VT8237S which is your Southbridge IC. It is responsible for things like your keyboard, USB ports and connectivity in general. The 4th image is a VIA CN896 which is your Northbridge and its responsibilities are video related like connection to your display etc. In your case that is most likely the IC that is giving you trouble. As of now I have not managed to find a schematic but will continue to look for one.
