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

Question

Monitors

Monitor ViewSonic VA1903wb
Previously, there were no problems. Recently something happened to him and the image became excessively bright.
That is, for example, a gray or light blue color is stupidly invisible.
I changed the brightness and contrast settings - it does not help.
I tried all the modes in the screen menu.
Tell me how to fix? Which radio element needs to be changed?

Answer 1

- first of all, I always smell where it stinks
- secondly, I inspect the board for visible damage, cracks, smudges and streaks
- thirdly, I inspect all capacitors for swelling (when it is swollen, the asshole clearly sticks out or the cross becomes not so clearly visible)
- then you can try with a multimeter poking around, maybe where the short circuit is on the resistance, or vice versa, infinity even at the highest positions of the handle, but if you don’t know what to look for, then it’s better to immediately throw this junk away, because. repair in the workshop will be more expensive than buying a new one
