Kérdésem a következő. Van egy Sony CD132-cd6 tipusú autórádióm. Tönkre men bent a betöltő motornál 2 db fogaskerék. Sehol nem birok hozzá szerezni. Van valakinek ötlete hogy hol lehet ilyet beszerezni.
A fogaskerekek adatai:
Dupla fogaskerék mind a kettő
Első:
Átmérő: 11,5mm 21fog vastagság:2,5mm, átmérő:8mm 9fog vastagság: 2,5mm
Második:
Átmérő: 13,5mm 25fog vastagság:1,5mm, átmérő:7,5mm 10fog vastagság: 2mm
Két gyönyörű Sony gépet hoztak hozzám javítani. Kellene rajz mert elég macerás hibák vannak.
Sony TA-313
Sony STR-414L
Ha valakinek van kérem tegye fel.
Előre is köszönöm
hi i am looking for the schematic diagram of a sony power unit.
Sony VPL-fx35/fh31/fhz55/f420hz/f425hzl power unit RPS9522M-02
or from part number 1-474-223-11
i hope somebody can help me out or if you have it partly from reverse enginering please upload or let me know.
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!
