Sony STR-DE935 Won't Power On
My neighbor figured there was no hope for his Sony STR-DE935 receiver
when it stopped powering on, so he gave it to me. I have done all I think I can, but I still can't identify the problem and it's driving me crazy. This is a great unit and I think it can be repaired. Can somebody PLEASE shine some light? Thanks in advance, John |

Thanks in advance, John Well not really unless you can shine more light on what you have done, found out etc. Otherwise its a bit like saying my car won't start. Gareth. |

Sony STR-DE935 Won't Power On
Good point. Sorry...All *I* really have done is open the case and
visually inspect for problems, poor connections, etc. A friend of mine at work took it home and tested it. AC Power - OK Power Switch - OK DC Regulations IC401 - IC1501 IC402 - IC1203 Q801 - IC1204 IC404 - IC1205 All OK IC1207 on digital board - could not find schematic - no output. Relay - OK Fuses - OK Suspect IC102 |

They also have a diagnostics facility. -- Trevor Wilson www.rageaudio.com.au |
