Sony XOD70 hi-fi torony kazettas magnojaban a jobb oldali csevek nem tekerik fel a szalagot. Megoldva!
Sziasztok. Van egy, a cimben szereplo hi-fi tornyom, melynek egyetlen problemaja az, hogy a (dupla) kazettas magnoban egyik mechanika sem cseveli fel a szalagot jobbra lejatszas uzemmodban. A szalag tovabbitodik, a zene hallatszik, de a jobb oldali cseve nem forog es 2mp utan mar a nyomogorgo feltekeri magara a szalagot. Gorscseveles mukodik mindket iranyban, mindket mechanikanal. Kivettem az egyik mechanikat - hatha okosabb leszek, de csak a gyorscseveles modjat sikerult megerteni. A lejatszas mod kisse bonyolultabb modon van megoldva, es mukodes kozben sem latni mi kene forgassa az orsokat. A szervizkonyv robbantott rajzatol sem lettem okosabb. Talan valaki kozuletek javitott/szedett szet ilyen mechanikat, es folvilagosit engem is. Elore is koszonom. Udv.
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!
Sony CMT-GPX7 tip. minihifi cd olvasoja neha oda-vissza ugral.
Sziasztok. A cimben szereplo keszulekem cd jatszoja szamomra furcsa dolgot produkal: oda-vissza ugral, es ezt nemcsak a zenen hallom, hanem a szamlalon is latom. A cd-ket egybol beolvassa, az mp3-at is, de a lejatszas folyaman elojon ez a jelenseg, barmelyik zeneszamnal. A kivalasztott zeneszamot egybol megtalalja, csak a lejatszas nem megy neki siman, folyamatosan. A mechanikahoz sajna csak ugy ferek hozza, hogy ha a keszuleket szetszedem, tehat mukodes kozben nem lathatom. Talalkozott mar valaki ilyen jelenseggel?
