If your TV doesn't support audio return channel (ARC, which is your TV audio routed back to the receiver through the same HDMI cable), you then need to connect your television audio-out to your Onkyo TV audio input, using a digital cable or an analog one according to the connections on the back of your TV. If you use a digital connection (optical or coaxial), make sure you have the proper digital port assigned to TV on the onkyo I/O assign menu/digital inputs.
In case your TV does support ARC, you need to activate it in the Onkyo's hardware/HDMI setup menu, either by turning on HDMI control (tv or receiver control each other via cable), or by turning ARC on (you'd probably need to activate ARC on your TV as well).
Hope this help,

This may not be a remote control problem. try turning on the tv directly from the tv and see if it takes longer than normal to power on. Sounds like a problem with the tv.

Repair the Power supply!

Try replacing batteries and reprogramming both remotes.
