Ihave a Sony d-250. only left channel has voice, right no. I replaced DAC-PCM66 chip,but the problem is still. nothing changed. I also tried to replace DSP CXD 1125,nothing changed.
1. if connects right with left channelof DAC, both sides have voice.
2. DAC P8-0V, P10-2.2V. P1-7.5V
3. if disconnect the cable of P1 (DACP1 that connects with Q429, as picture show) only right channel has voice.
4. replace DAC and DSP chips,nothing changed.
