Monitor Screen darkens after spark sound is heard behind?
Ive been happily using my computer for...3year or so.
But Ive heard a high pitched(say near 5000hz) spark sounding noise(like when you rub your had in front of a tv as soon as you turn it on) from the back of the monitor and that same instance the screen slightly darkened.
It a Sony CRT Monitor i don't know what is going on but its like the third time it happens
Edit:Its happening more intense now whats going on?
