Sziasztok!
Mi nap került hozzám ez a kis jószág!
A Hiba jelenség az hogy néma (hangügyileg), minden más rendben üzemmel.
Kapcsolási rajzot megtaláltam de nem lettem okosabb.
Kimértem a tápvonalakat minden fesz. rendben van. Vagy van valami amit nem néztem?
Találkozott már valaki ilyesmivel?
Sziasztok!
Van nekem egy Jbl sub 178 am . egyszer csak nem működött az
automata on off funkció. Ha nincs jel ki kéne kapcsolnia.
Most bekapcsolt állapotban maradt.
Fent van a tanyán a kapcsolási rajza de sajnos
nem találom a hibát.
Segítséget szeretnék kérni,hogy merre keressem a hibát.
Köszönettel

Hi,
I am looking for a schematic of Nova DXP1400 SMPS Power Amplifier.
I have one to repair it.
The issue is, that of power off, the loudspeaker output siwtch a flowting voltange to it about 3-5 sec. which is switch between positive and negativ amplitude.
Any sources for it. Nova stops producing/repairing it, so no support at all.
Thank you
Sascha
