hissing power supply m50wh72s (rca dlp)
Posted: Thu Sep 03, 2009 1:55 pm
guys, i'm stumped and need some help determining what the problem is:
there's is a relatively loud hissing coming from my power supply. it sounds like a tire losing air, not a buzzing or a humming. physically, i don't see any bad capacitors on the board (I've replace 4 that were bad). I'm wondering if it's another capacitor(s) making that sound, or if it's the transformer?
