Won't turn on.standby light on,fuse under cover is good.what next? onkyo tx-sr605

It likely needs to be opened and looked at---a fuse is possible or may be a good idea to take it to a shop for an estimate.

Sony TV codes for the Onkyo TX-SR605 are : 0000, 0650, 1100, 1167, 1300, 1505, & 1651.

Instructions for the Onkyo RC682M and more remote codes are available here. The Onkyo TX-SR605 manual is available here.

I hope that helps.

Hi...1st off ...make sure all the speakers are connected at both ends.
2nd..buy a new cat..one that doesnt drool.
If it's still stays in Stdby after checking speakers, It might have blown an internal fuse cause thats where those darn stereo people put them now.

Your program source may not support a 7.1 format. Try switching to 5.1

If the unit will not leave standby I would remove all power, disconnect *all* connections at the back, reconnect to a power source and try powering on. This will eliminate any connection causing the Onkyo to stay in standby due to a short. If it still will not enter power-on mode, you may want to look at the power source (is it properly grounded?), but beyond that the unit probably needs to go back.
