: I have change the place of the transistors sb507 and sd313 with no results.Can it be the 2 Elna caps(4700µf_35v_85°c)?
: The electronics parts seems to be.
: Please give me some ways to go.
: Excuse my language caus i'm french guy.
: By!!
If you mean the caps of 4700uF in power supply so would even the channel bad. You have to trace the signal from input to output in order to locate where it goes bad. You can compare left channel with right channel and see where it´s different in voltage. A schematic would be a great help. You can find the sercice manual with all information for settings and it also contain the schematic. Click on link below.
