Have a hantarex polo 33" monitor that is displaying darker colors.  The monitor was displaying brighter colors and recently is getting worse. The brightness and contrast is turned up all the way. Anyone have an idea what to look for?

try adjusting the screen volts(maybe just a dirty pot) on the flyback transformer
check for cold solder joints
if all that fails then replace all the electrolitic capacitors
one other thing,if its a standard arcade setup check your +5volts from the power supply is set correct
