Re: Dell 1901fp

I am new to this forum, I currently have a problem with one of these Dell monitors. My problem may be bad CCFL or inverter supply. I haven't looked into much yet.
From what you describe as whining is a power supply trying to run at its designed frequency. You have some kind of short on the power supply load or a defective component in a power supply.
Check all power supply voltges & see if they are correct. This may give you aclue to where the defect may be.
