I just tried the analog and the logic board with a different CRT and still is the samething.. However I've noticed something else .. I have another macintosh se which ive just turned on and i hear the normal Bong sound but when i turned this faulty macintosh se on, it made a different bong sound.. It just didnt sound the normal one .. I am not sure how to explain what it sounded like but it just wasnt the bong that you would normal hear from the macintosh plus, se or the classic ii.. Its sounding a different bong.. Any help with this?
