I notice this broken active speaker laying around at my school music club. The woofer was not playing and i figured out that the amplifier plate was the cuprite. Follow me on FB : profile.php?...
Merci pour cette vidéo très bien détaillée. Grâce à toi j’ai pu réparer mes enceintes Eurolive B212D. J’avais le même problème. Le même défaut de soudure sur le même composant ! 🙏🏾
bonjours, ça pourrais venir de l'amplificateur. Faudrait démonter et tester les hauts parleurs au multimètre pour savoir si ils ont pas été endommagé lors du "boom". Puis observer l'ampli a la recherche d'un composant cramé ou visiblement hors service.
HELLO EVAH! I noticed that one of my EUROLIVE Powered speakers only had sound coming out of the woofer so I ordered and installel a new Tweeter Diaphragm but when I powered the unit up it's squealed!!! I took it back apart double checked all the wiring everything is in the correct place! Tweeter is mounted in the correct position! There's no smell or anything burning from the Amplifier section! Can you tell me what that could possibly be wrong!
If you have an oscilloscope, try to identify were the frequency is generated. (Eq input board, or main board) if you don't have oscilloscope. Try to connect the low and high input of the main board to ground. That way you can identify were the frequency is generated. Tbh, I'm guessing that your power amp Chip might be blown. But not sure about that
