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.
Erősítő- cd összekötő kábelt, de milyet?
Sziasztok!

Szertenék összekötő kábel vásárolni a Sansui G6000 és a cd közé ( ez több változós még). Milyet ajánlotok a realitás talajánán maradva?
Kiegészíteném, RCA-RCA összekötéséhez használnám.

Videoton rt7300s rádió tuneren FM sávon csak zaj van
Hozzám vágtak egy Videoton rt7300s tunert. Van benne élet, viszont fm sávokon csak folyamatosan FM zaj van.( nehogy szó érje a ház elejét , nem súgás) Hangoláskor a kijelzőn úgy tűnik, mintha működne, meg meg áll, de csak az FM zaj marad. Az FM mute gombra nem reagál. Automata keresésnél elnémul a keresés alatt, kéziben folyamatosan FM zaj. A feszültségek rendben vannak. Az AM sáv hellyel-közzel működni látszik, de erősen zajos az adó. (csak a Kossuth szólal meg)  Keresgéltem a fórumban, de ilyen hibáról még nem számolt be senki.. Minden ötlet jól jön.
Előre is köszönet mindenkinek.
