Monitor backlight in the middle (higher brightness), can it be fixed?

Question

Monitors

There is a monitor https://market.yandex.ru/product/10572699?hid=9105...
Presumably the Viewsonic VX2452mh model or very similar.
Over time (several years of operation) in the middle, the brightness of the image increased significantly, and the contrast dropped. Can be described as backlight unevenness. Can it be cured or corrected? Why does this occur?

Answer 1

In your case, this is either a malfunction expressed with problems in the power supply. Or it's a defect in the matrix. In the first case, it is enough to disassemble the monitor and inspect the board for swollen capacitors. If everything is normal, then the matrix degrades (I saw this, but it went in spots there).
