instalatie craciun

Recommended Posts

Daca s-au dus diodele redresoare si cablajul aferent, mai merita reparat. Daca s-a dus controlerul sau tiristorii, atunci altul nou ! De obicei e de vina condensul care se formeaza pe placa si care provoaca scurtcircuite, de cele mai multe ori devastatoare.

Schimba toate diodele, refa traseele intrerupte (dupa ce speli afumatura de acolo) si apoi verifica tiristorii aceia mici ce seamana cu tranzistorii.Daca e vre-unul din tiristori dus, poti fi mai mult ca sigur ca s-a dus si controlerul (integratul de comanda) si nu mai ai ce-i face.Tiristorii sunt comandati direct de controler si arderea unuia va afecta si partea de comanda.
