Salve,
Cassa bruciata Bheringer Eurolive B215D
Si tratta di una cassa Biamplificata
con amplificatore per i Bassi in classe D e per gli alti un ic TDA7293.
Oggi finalmente sono riuscito a risolvere questo guasto.
Lo voglio pubblicare per aiutare il forum ringrazio per aver auto lo schema.
Stato della cassa iniziale al ricevimento
>accensione led rosso in protezione nessuna uscita audio in funzione.
1°passo: verifica del TDA7293
in corto circuito pin 7 con pin 14 = è bruciato!!!! da sostituire
2°passo: verifica oscillatore IC11 IRS20955 = NON OSCILLA bruciato!!!! - da sostituire.
- Fatto... MA NON FUNZIONA!!! esamino il circuito meglio R72 rotta C89 in -- corto. Sostituisco anche C95
- = FUNZIONA!!! PER0' INTERVIENE IL LIMITER.
- Ho dovuto fare questa modifica per urgenza. Del cliente.
- Momentaneamente ho variato il valore di R38 da 100K A 10M.
- IL LIMITER INTERVIENE MENO.
Sè c'è qualcuno che mi può passare una dritta
Spero di essere stato utile e di aver decritto bene il mio intervento
Vi saluto buon lavoro a tutti
Lucio.
Jó estét Mesterek! Ismét kérnék. Hoztak egy Blaupunkt Dublin C32 rádiót. Cód-ot kér.Irnám az adatait :BP212031056395 /DUBLIN C32 alatta 7 642 120 310 Az alvázba beütve 8 635 123 208.2 A hátoldalon viszont van két szám papíra ragastva (gyári)C1202 C2205.Előre megköszönöm a segítségeteket:Öreg Tom.
Üdv ismét mesterek. Még sajnos nem jött meg kinábol az ESR - müszer, de gondoltam ha már elöbányásztam akkor belenézek.Hátha csak a biztositék ment ki annó. Közben olvastam a neten, hogy sokszor valami höbiztositék van a trafón,és az szokott elszállni.Na most én megnéztem , kivettem megforditittam a trafót de semmi nincs a trafó lábain. Akkor ezek szerint nem mindegyiken van?
Azért a trafo szerintem a bünös mivel a csokin nem mértem semmi voltot.
Remélem ezt már meg tudom javitani.
köszi elöre is a asegitséget.
