Question Sections of my monitor screen are dim ?

[PyramidScheme]

About a month ago, sections of my monitor screen got really dim, on the left and right edges mainly. Now it's gone back to normal but the middle section is still a bit dim. Is this a fixable issue? Would it be worth the risk of trying to repair at home?

Is that some kind of charger sitting on your desk under the monitor?
