I have a problem with my Toshiba PC monitor, when it's switched off a grey patch appears - it isn't visible when I'm using it but when it's off it is and looks awful. Can anyone advise me as to why this is happening.
Moisture on the inside of an LCD screen will usually be visible when the screen is switched on, as well as when it's off. Such patches will gradually disappear if the monitor is kept in a warm environment.
If that hasn't happened after a couple of days, the problem is not moisture.
