I would like to configure my receiver tx-sr303 to use the 5.1 configuration?

The 0-83 error indicates a problem with the firmware update.

Try resetting the receiver's BIOS by following these steps2:
Unplug all cables
Un-Power the receiver
Power the receiver
Before the receiver gets into the "Enter for updating" message, press Tone + CBL/SAT + ON/STANDBY. This will show you either the volume numbers or get you into settings of the receiver's speaker configuration.

Press CBL/SAT + ON/STANDBY. This will clear the BIOS and show a "Clear" message on the display. Wait until you hear a couple of clicking sounds for the receiver to turn on and off the power.

Make sure Speakers A + B buttons are both pressed in.

Run the test tones. If you can hear Test Tones then it's just a configuration issue.

7.1 would have Surround Back L and R.

6.1 would have just one back there (SB). It defaults to the Left output on the Pre-Outs if you ever go that route.

This being a 6.1 receiver it does not support two SB channels BUT you can configure those amp channels for a separate Zone supporting 2 speakers. Confused?

The manual shows a single SB speaker connected to the left side on Page 27. THAT would be consistent with a 6.1 configuration.

The TT should be connected properly for the way it's configured (Line Level Out to any Line Level In OR Phono Out to Phono In) and NOT any other way.

Some background reading:

No configuration needed, it should play normally. Alternative you can use a jack to 2 RCA cable like this

and connect your iPhone at the audio L - R inputs as seen on this picture

over heating your amp with a problem and its going into the protect mode... better stop before it dies for good...$$$ to fix....speakers mismatch or wrong ohm rating for starters bad speaker, bad xover...

when the stereo or mono listening mode is selected only front speaker and subwoofer produce sound--------make sure that speakers are configured correctly.
and you select surround sound in listening mode.

you have to check your output configuration
