Sziasztok!
A fenti HIFI kijelzőjén a PROTECT hibaüzenet villog. Végfok panelt lehúzva sem változik a helyzet.

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!
Üdv! Sajnos betörték (kijelző, minden más OK), ha lenne valakinek bontott ilyen készüléke, vevő lennék a plexijére, vagy a komplett előlapra: http://www.kephost.com/view3.php?filename=56lgkrzav1uuxvx7gxz2.jpg

Sziasztok
Van egy régi Sony TA117R erősítőm. Sajnos nincs hozzá távirányítóm. Kaptam egy fülest miszerint a Somogyi RC2 univerzális tudja ezeket a régi hifiket is. Nos egy szintén sony régi CD simán beállítottam rajta de ezt az erősítőt nem sikerült. Azért volna jó ez a távirányító mert egyszerre 10 gépet kezel és olcsó 900ft. Tudtok erre valami okosat?
Köszi Laci
