can you help me solve this problem

[Alec]

The light on my screen is dim. I can't see or read any thing on my screen,
very well.

Maybe look for the brightness control.

 

[David B.]

I don't see what this has to do with performance, but if the brightness
control doesn't work and this is an LCD, you either have a bad inverter or
bad backlighting.
