I'm doing an install and setup with a MX-900 remote. Most of the components are new, but the receiver is this older Sony STR-DA50ES. I don't see discrete on/off in the editor code set. Does anyone know or have on/off discretes that will work? I'd even take the toggle on/off if that is all that is available. The customer doesn't have the original remote, so I can't learn it.

There are no discrete codes for this device. Have the customer turn on the power with the 'POWER ON' boutton for the TV , Receiver and cable box (if exists) and then select an activity which will change the inputs. I just did one of these a couple of months ago.

Thanks vbova. How/where can I get the toggle on/off code?
