I am searching for the aiwa minitower NSX-AV320 a circuit- diagram/servicehandbook/hint ... The equipment worked well over several years and stopped rapidly its function. No AF-output from both amplifiers (dolby surroud and simple amplifier) ... I am sure that its not a fault of the amplifiers, I believe that a support voltage is missing, but without a drawing a hard job to trace and find , especially with smd populated circuit boards !
for any help thanks in advance ...
