The image on the monitor is too bright. How to fix it?

Monitor ViewSonic VA1903wb
Earlier there were no problems. Recently something happened and the image was overly bright.
That is, for example, grey or Aqua color stupidly is not visible.

Changed settings of brightness, contrast does not help.
All modes in the menu screen tried.

Tell me how to fix it? What is the radioelement need to change?

- first, always smell where it stinks
- the second thing is visiting cost for visible damage, cracks, smudges and stains
- the third case inspected all capacitors for swelling (when it's swollen ass clearly sticks out or cross is not so clearly visible)
- next, you can try a multimeter to poke, where can short-circuit on the resistance or Vice versa infinity even on the largest positions of the handle, but if you don't know what to look for, it is better to throw away this junk, because the fixation of the workshop will be more expensive than buying a new one
