I recently was on my Macintosh SE and after using it on and off for about 2 hours (turning it on, adding software, powering off, waiting a few minutes and repeating) I heard a strangle crackle noise from the crt. It first happened after doing the last cycle, where it made a noise similar to the noise a wooden wick candle makes, although it was quieter, and for about 2 seconds. then I powered it on 10 minutes later it made the noise again but it lasted longer, and gave me a sad Mac icon, with a ton of screen artifacts. but after waiting a few days and leaving it unplugged, I turned it on again and it made the same noise although it was much shorter, but successfully booted. Does anyone know what is causing this and how I can fix it?
