It will get worse, I use to have a 17" Studio Display (CRT) and the snap/pop would happen every few days, but after a few weeks of that it started to do it as often as every 5 minutes, rendering it unusable. :-/ The problem is the flyback transformer as an earlier poster said. You can repair it yourself, but it requires soldering very high-volate parts. A better alternative would be to buy a new board for the display on eBay, if you can find one.
