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.
Üdv.Érdeklődni szeretnék hogy a fent említett hangrendszer mélyládájába tönkrement a vezérlő csipp:SN8P2714SB
Valaki tudna-e segíteni hogy hol kapni ilyet, vagy esetleg van-e helyettesítője?
Sziasztok!
JBL tv boost "sound bar" javítása közben elakadtam. Ez 19V betápról megy. Nem csinál semmit. A belső tápja egy AELF feliratú, 6 lábú morzsa. Mi lehet ez?
Vagy mekkora tápot csinál a többi belének? 5V? 3.3V? Van hely, elfér bele más is, de a kimeneti pufferen nincs semmi villany.
Nincs valakinél szétszedve egy, mérésre? :)
Szerk: nem tudok számolni. 8 lábú :)

Üdv Tisztelt Mesterek !
Szenvedek egy Peugeot Clarion autórádióval.
Beszivárgott a klíma és meghalt a végfoka.
TDA-7385 van benne , de nekem meg csak TDA-7384 , illetve 86 van kéznél.
A JÁGER a TDA-7385-re 25QILP tokor ír , míg a TDA-7384-re 25 SILP-t.
Valószínű vak vagyok, ill. tényleg az , de mi a különbség ?
Betehetem helyette?
A teljesítményen kívül mi a különbség?
Ráadásul csak az autóba tudom majd ellenőrizni.
Tisztelettel:Öreg Tom
