Onkyo HT-R590 No Sound

[mrd05d]

I am very new to electronic repair and am trying to fix my Onkyo Amp (HT-r590) I have the service manual but could use some help as to where to start looking if anyone is up for it. The receiver turns on fine video in and out work fine on all the channels but sound does not work on any of the channels. I guess last week when i was out of town my kids said it was popping and the sound would cut out. They turned it off and back on to reset the sound. Now its not playing sound at all.

Thanks

maybe upload the service manual, so folks can have a look? Also hi res, straight shot pictures would be nice.

I will upload some pictures when I get home as well as the service manual. I believe it has already been uploaded here before but I will also upload that when I get home.

Re: Onkyo HT-R590 No Sound

does it give an error code?
For starters I would check the solder joints of the output bricks. Resolder every pin on each brick and see what happens. They crack, dry joint, some will look good and still be bad etc...
