Hello,
If it is the light luminosity changing then either the CCFL lamp of the screen is damaged or the inverter that drives the CCFL lamp.If the lamp is faulty then you should either change the lamp (lcd screen needs to be disassembled) or replace the entire lcd screen.If the inverter is faulty you will need to replace or let a technician repair the pcb that the lcd and the lamp connects to and a flat cable from the cpu board comes to it.
If it is the contrast that changes but light luminosity remains the same , it is most probably a screen issue and the screen will need to be changed.
A video of the issue you experience will clear things up!
