Hi, my display is black but connecting the PC with a external TV I can work. This happened after taking the plug out to change the place of the PC. Does someone know if this could be a minor thing like a broken fuse or do I better give the PC away?

If there are any blown fuses the system would not turn on. 

There are a number of possibilities. Moving might have caused a loose cable to disconnect.

 

There is an excellent video here on replacing parts

Turn the system on and use a flashlight to shine into the screen.  If you can see text or images (very faint) then the backlight is defective and is easy (IMHO) to replace.  Backlight power power supplies have a part# , are cheap and are available.

 

Once back is off you can poke, push, or fondle cables and see if the display starts working. The backlight wiring can be high voltage so use a stick of wood or ruler to poke with.
