Sziasztok
Kerult hozzam egy Sonos Play 1 hangfal.
Szetszedve eleg ijeszto volt, viz folyt bele es ugy volt betaplalva halozati feszultseggel.
Ami biztos: a halozati biztositek (T2A) szakadt es felrobbant, azonkivul a Graetz hid ket diodaja zarlatos, az egyk AC bemenet a + al vezet rovidet, a masik a -al
Tekintve, hogy a viz vezetett, valoszinu egy ideig 230AC-t nyomott a kondira es a tapra.
A pufferkondi mintha kicsit pupos lenne, de nem biztos.
Kiszaritottam, kicsereltem a nyilvanvaloan hibas alkatreszeket, meregettem benne, rovidzart vagy hibat keresve. Nem talaltam semmit, ezert betaplaltam.
A biztositekot rogton kivagta.
Ekkor megint a kondira iranyult a figyelmem, a chopper reszen nem lattam zarlatot.
A kondi 100uF/400V
Merve nekem nem tunik rossznak.
94.04uF
Vloss=1.9%
ESR=1.5Ohm
Keresgeljek tovabb? Nyilvan nincs itthon ilyen kondim, maskepp cserelnem.

Sziasztok!
Helyettesíthetem a SONY CXP82852-141Q típusú procit egy SONY CXP82852-136Q-ra?
Adatlapot nem találtam külön róluk..
Köszönöm!
Üdv.
Sziasztok! A címben szereplő tuner rajzára lenne szükségem. A tanyán található SD végű sajnos teljesen más. Nehezíti a dolgomat, h teljesen szét van túrva.
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.
