Monitror Belinea 106020 problem

[pixell]

I have a Belinea 106020 19" monitor five years old.
Monitor worked just fine untill once, after booting in to windows picture on it shrinks and green color disappear.
From that day LED on it just blink in orange colour, no picute, nothing.
Before this incident, when computer was on stand-by, LED just lighted orange (not blinking), and on power state was green.
If any one know a solution for this king of problem, please reply.
Thanks
