HP LCD 25.5 MONITOR

Most often when I shut down, the monitor produces a very loud screeching sound, almost sound electrical.  I have only had this computer (Pavillion Elite) for a week now.

Re: HP LCD 25.5 MONITOR

The sound to the w2558hc can be digital (HDMI) or analog(RCA).  I am guessing you have analog based on the symptom.  If so, you probably have bad AC power ground from your home power source or ground failure on the PCaudio port.

 

Second possiblity is improper voltage traveling down the Video cables from the PC Card/PC ground.
