Marantz ST-15S1 tuner Fm-en nem talál adót
Kedves fórumozók!
Vásároltam egy ilyen tunert de az FM rész csak keres keres keres, nem talál adót. AM en működik a másik szimm antennabemenetről kis keretantennával. 
Gyári beállitások visszaállitása megtörtént. Fm antenna rendben mert másik rádio szól vele.
találkozott valaki ilyennel? Esetleg javitott ilyet?
Van esély javítani ha mondjuk légköri túlfesz villám agyoncsapta az Fm bemenetet. Meg ki tudja még mit.
Service manualt nem találok hozzá. Állitolag ugyanaz az fm része mint az ST-7001 tunernak. Olyan service manualt se találok.
Segítséget kérek!
Köszönet!
Imre
 
Kenwood kdc-psw9524 probléma
Sziasztok. Adott egy fenti autórádió.(dupla előlapos, jó kis cucc lenne..) A gond: Hozták, hogy nem kapcsol be. Nagy nehezen kideritettük, hogy nem a saját levehetó előlapja van rajta, hanem valószinüleg egy másik készüléké.( teljesen megegyezik, még a leirások szerint is) Ahogy olvastam ez csak a saját előlapjával megy, de hátha van rá megoldás.. ( a régebbi maszkos modellekhez is voltak olyan eprom tartalmak, amiktől nem kérte pl. a maszk kulcsot...) A készülék nem lopott( az ismerösőm akié, nem olyan ), hanem angliából való, így már akitól vette, az sem utolérhető. Esetleg valami ötletet várnék a megoldásra. Köszönöm. Sziasztok.
repair sony amplifier str-de254
Want to share: Have downloaded the schematics from this forum to help repair the amplifier of a friend. Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies. When one takes the main board out of the chassis and switches the amp on, there are up to 20 volts difference between the eart (and hence reference) of the pre-amps and the main amps. Luckily the amp goes into protection but from a design point of view it is not nice to rely on screws and aluminum face plates to conduct up to 0.2 amps of current from one supply to another. What I did is solder wires to every eart point and connected them on the main board to make it stand alone and not rely on conducting current through the chassis anymore. Bad design, simple repair but took some digging in the schematics to find out what exactly was going on!
