TV VCR receiver Troubleshooting kindly reply

I want to set the input selection on my receiver and I want to make HDMI as the default one. When turning it off, and then turn it on again, it is set to the default connection.
However, when I turned the receiver off for more than 10 seconds, it will be set to TV/SAT.
How can I make it firm and set the receiver to HDMI automatically?
Please help.
