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.
