Hi all.

I have a becker BE6507 stereo from a BMW E39.  It has no sound output on 3 channels.  I am looking for a schematic or any repair tips.

Thanks.

check 2 smd transistors near the middle front they trend to go open curcuit apply heat to them and see which one will comes alive with the heat and then replace it.( these transistors are on the pre amp)
