pls help with serv.manual 4 this amp,only front speakers has no outpyt.all other s are ok.
 

SunnySkuyguy-thnx ,since no protec msg is displayed, i assume nothing is shorted on the pre amp or pwr amp section.I had one same amp with dry jointed relay on the channel that had no output.Now this amp has 14 transistor i need schema for going directly to the concerned section.Since other channels are ok ,that means pwr supply and other stages are ok.pls send schema.
 

thnx Dominik, i was able to repair a left-front shorted pwr output transistors and a resistor pair,so a short blew two 8amps fuses.Microprocesor history showed a shor.Thnx Sony for fusing this left and right front channels separatetly .,unlike old Sony amps where a single shorted channel will make the amp to go to "protect" mode making all channels unuseable.
