Question about CTX P772 17" LCD Monitor
My monitor is making noises, like an electrical bzzz. Could it be a corrupt profile or is it hardware? other than that, the monitor looks great.
Its a bad power supply or a bad ballast. If it sounds like a hiss it will most likely be a capacitor. If it sounds like a crackle it is most likely a bad resistor. You can usually smell it when a component fails. It will smell like hot automotive brake.

It the buzzing is directly from the back of monitor chances are its A noisey transformer.
This can be rectified by mixing up some epoxy resin type adhesive and spreading it over the windings of the noisey transformer.
PLEASE ENSURE MONITOR IS DISCONECTED FROM MAINS SUPPLY when doing this work.
