Right after I wake my monitor up from it's sleep mode it flickers around the edges on & off for about 30 seconds and then makes a fairly loud "popping" or "snapping" kind of noise, gives a big flicker and then all seems fine. Until of course I wake it up from sleep mode again. It's been doing this off and on for about 2 weeks now. Seems to be doing it more often lately. Is she dying?
