Bheringer Eurolive B215D
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.
MAXIMAL 286 Rádiósmagnó HA13001 végfok IC helyettesítése HA1394-el [MEGOLDVA]
Sziasztok! Kipukkant ebben a magnóban HA13001-es sztereo végfok IC, kölcsönadták valakinek az meghosszabbitotta, a drótok kopaszon toldva lettek es összeértek, az IC ára rettenetes nem ér az egész magnó annyit. Legalabb egy 500 sémát atneztem hogy talaljak helyette valamit, vegul is legjobban hasonlit a HA1394 (2 EUR) ugyanazok a tápok,bemenet, kimenet meg a tok is ugyanaz. Egyedul az pin1-es lab nem testre megy hanem 100uF-en keresztul megy a testre,pin6 tesre megy. Bekötöttem a HA1394-et es meg se nyikkan, pin3,4 bemeneten van jel, gondoltam biztos rossz az IC, IC kivesz masik mas szerias betesz ugyanaz a helyzet. Nagyobb jelszintu jelet adtam neki akkor nagyon halkan torzitva recsentget..Tápja egyoldalas 17V, ez megfelelô, hangszórók jók. HA1394: HA13001:
