This seems like a shot in the dark but there are a lot of smart people here so I figured asking never hurt. As a future engineer I want to tinker and it was given to me so it is no loss. First I know what it is not: any strange settings, the connections on the outside and the four fuses inside. It powers on just fine with nothing strange but no sound what so ever. Is there any common things to look for in general or with this brand? Thanks so much and let me know if anymore information would be helpful.
Your "handle" says it all! If you have never done service work before, don't start with a complex modern receiver.
First off you need an understanding of electronic circuits. You need the circuits and service manual for the unit you want to repair.
You need lots of test equipment and the knowledge to use it. Even if you pick up the gear on eBay, it will still cost more than the receiver is worth.
Sorry, but there is no help for a post like this.
You need to gain in knowledge wisdom and experience before tackling a project like this. I have been building and servicing my own gear for over fifty years. However I would be circumspect how deep I got into a unit like that. I would be checking power supply voltages and looking for evidence of output device failure putting the power supply in protection mode. I would not go deeper than that. I would not do anything without a service manual, and not without all items of test required to follow steps outlined in the service manual.
The other issue is that there are high voltages in the equipment. Lack of knowledge and inexperience can cost you your life.
If you become an engineer, and I hope a good one, you will look back on this post and have a good laugh.
