Am o problema de ceva vreme cu una din triple iar pe net nu am reusit sa identific piesa defecta, este o cutiuta (cat o cutie de chibrituri) care are in ea din 2 condensatori si sub ceva tranzistori ,un strat de silicon foarte dur acopera lipiturile, intra in ea 2 fire si ies alte 4 care duc in drosere sau ce or fi alea . Cand apas pe ea se aprind triplele, ceva nu face contact acolo si nu am cum sa vad ce este in ea.

Stie cumva cineva ce este acea cutie si ce rol are, o schema electrica poate, sau macar daca se poate cumpara separat.

 

o sa revin si cu o poza, momentan nu stiu cum sa pun poza.
