Simens NCDR 1100 defect

Recommended Posts

Nu scoate sunet nici pe radio nici pe CD ( Functioneaza toate optiunile pe care le are rc ,, nu merge cautarea frecventelor ,afiseaza doar frecventele anterioare iar in difuzoare nu se aude nimic nici pe radio nici pe cd )Va rog daca poate sa mi spuna cineva ce ar putea fi . RC nu are display ,foloseste afisajul masinii .Multumesc!

Nu are amplificare ,nu se aude nimic in difuzoare ,iar la masuratori pe integratul TDA7454 este tensiune numai pe pinii 6 si 20 (+12v) ,pe restul pinilor e (0v) Pate sa fie integratul sau altceva inainte de el.Integratul nu se incalzeste deloc , e rece . Am un tda 7456 este oare echivalent direct ? Multumesc!

am si eu un ncdr 1100. Problema la mine e ca unitatea nu mai porneste din cauza unei piese numite TL1454. Aveti idee unde as putea gasi asa ceva, sau o alta unitate la fel care sa aiba alta problema?
