My CRT started making a wierd high pitch hiss or whistel when I'd turn it on but would go away after a few mins and it warmed up. All the suddon now even after it's warmed up it's now making a chirping noise every 2 - 3 seconds and it's not going away. Picture is still great but this noise is driving me nutz! It sounds like a tweety bird is in there that is somewhat quiet but it's the type of frequency that just peirces the ears. Anyone know if I can do anything or is it pretty much the end of the road for this monitor if I can't take the chirp any longer? It's a 2 year old low end 17" CRT, Mag Innovision is the make. BTW I already tried smacking it a few times but that didn't work.
