shine a light close to the screen to see if can see anything as might be a back light issue.

So you think its the LCD screen not any cable? and I should buy one?

you would have to disassemble the screen & the upper half of the laptop to get access to all the wiring to the screen. maybe there is an invertor board needed to power the screen & maybe it died. start disassembling.
