Hi, I'm not a pc person by any stretch of the imagination. But I have had this problem too. I called a PC repair shop here and they said it was the Fly Back. Whatever that may be and wanted 300 and some odd dollars to order a new one.
Lightening hit our regular TV and I had to have the power something fixed in it. 30.00. While the TV repairman had the back off the TV I saw nasty dust. Pretty thick. So I thought what the hay. I blew out the back of my monitor and no more flickers, sizzles etc. Thats been a year now.

Just thought I might give you my story. I'm on that monitor now.
