Sziasztok,
Onkyo TX SR307-es HDMI-s erősítőnek nincs hangja. Bekapcsol, minden funkció működik rajta de nem jön ki rajta hang.
A HDMI-DSP panelen néztem az IC-ket, egyik sem BGA tokozású, mind SMD. Gondoltam, ezek nem forrasztották ki magukat mint a BGA-s társaik.
Kicseréltem ezen a panelen az SMD elkókat, a helyzet nem változott.
Érdemes újra forrasztanom az SMD DSP ic-t?
Valakinek hasonló helyzet?
(egy érdekesség: ha a B hangfal kimenetre kötök hangfalat és a hangerőt max-ra teszem halkan ugyan de jön ki hang az erősítőből)

Hello, I am in the process of repairing the Mackie ProFX12 V2 mixer for a client, and am running into the unavailability of schematics. Does anyone have a copy they could share? I have already reached out to Mackie directly but am still waiting for a reply.
Additionally, I am having trouble identifying the failure mode for the two channels that have failed: one produces loud static (indicating bad op-amp or feedback resistor perhaps?) and the other has the right channel producing a 60hz hum, the other is functional. (see board photos, with the two failed channels being marked with "F". The browned area is residual flux from having replaced two opamps, and having reflowed other components around them)
Any help on either of these fronts would be invaluable. I have mainly worked in laptop and computer repair, and am just getting started with my first scope and first set of board level repairs.

Sziasztok!
Kérlek benneteket,próbáljátok felismerni a végfok ic-t,felirat hiányában.25 V-os szimpla tápja van,kb 30 W-os lehet.Torzít közepes hangerőnél.A két kocka alkatrész mi lehet? Előre is köszönöm!

Sziasztok!
Szeretnék érdeklődni, hogy rajtam kívül, javított-e valaki ilyen erősítőt végfok hibával, és sikerült-e beszereznie hozzá alkatrészt??? (STK1039)
A tápegységet, a tanyás rajz alapján sikerült kijavítanom (köszi) :D el is indult, viszont végfok alkatrészt nem találok hozzá!
Bármilyen megoldás, ill. helyettesítő alkatrész info érdekel!
Előre is köszi!
Üdv: Zsolti
