I have been using several silver remote controls made by Universal Electronics to operate the on-off power of a Motorola DVR, Sony TV, Sony CD Player, Sony DVD Player, and Sony A/V STR-DE635. I replaced the DE635 with the STR-DG710 and cannot locate the Power on-off code.

I attempted to used an RCA Learning Remote to learn the Power code but did not succeed.

Any help will be appreciated.

Thanks in advance.
