imac 333 screen snapping --scary
The Header says it all. I have an imac 333 and the screen has started to snap. It's like static is discharging, but it will happen when I am in front of the computer, or when I am on the other side of the room and haven't it touched it in a while. The screen flickers and makes a snapping sound. Sometimes the snaps are quiet and the flicker quick, sometimes the snaps are loud and I almost lose the picture. It's fast, and infrequent, but has become more frequent in the past month. It isn't more than two months old as a problem. I've had the machine since they were introduced, so it's old and a workhorse.
This is my first issue with the machine, but it's a scary one. Will this box blow up, shredding my face with a thousand fiery needles of glass? Could someone give me some insight on this one. Thanks.

Sounds like your analog video board is either loose or beginning to fail. Time for a service shop.
My iMac266 was doing the same thing several weeks ago ... did it frequently for a couple weeks ... now I haven't noticed it at all for about a month.
I really don't know what caused it ... maybe some dust collected on the rear of the CRT ? (inside the case)... perhaps dust on the magnetron caused some arcing and these snaps till it burned away ??? a poor theory, but i AM an amateur.
In any case, a CRT is a vacuum tube ... so if it were to have a catasrophic failure, it would IMPLODE (not explode), so you should be relatively safe sitting there !
My screen snaps too. Especially when I'm concentrating hard. It often makes me jump out of my seat. Mine's been doing it since I bought it in '98. Screen still works fine.
