Fax Philips IPF325

Recommended Posts

Va salut,

 

Fax-ul din titlu nu mai functioneaza in urma unui soc de tensiune.

As avea nevoie de manual de service ca sa vad cum se deface ca sa ajung la sursa. Am incercat sa-l desfac dar are niste cleme pe care nu vreau sa le rup.

Ar fi bun si un manual de srvice de la un model asemanator.

Daca in sursa are un MOV, atunci s-a ars MOV-ul si siguranta. Daca n-are asa ceva, atunci sursa e facuta pilaf.

Multumesc.

Am desfacut faxul (o clema nu a scapat si s-a rupt) si am desfacut sursa.

Un varistor e prajit, la fel si siguranta.

Ce caracteristici trebuie sa aiba varistorul ?

Pe sursa scrie:

Nominal voltage: 200 - 240V ac

Nominal current: 0.25A

Nominal power: 25W.

 

Multumesc.

L-am rezolvat.

Am scos un varistor de pe o placa dezafectata (cred ca a fost un copiator), am verificat piesele afumate (termistor si un condensator) si puntea de diode, am inlocuit siguranta si functioneaza.
