Look on the back of the system, if there is phono input, that is what you can use to connect the turntable without using an external pre amp

Power outage overnight. Now, Onkyo TX-SR603X no

Depending upon the type of power outage, you may have more of a confused receiver than a defecive one. Try unplugging the unit for an hour or so to see if that resets the whole thing back to "normal". If not, then further investigation with a scope or logic analyser will be required to determine whether the problem is with the internal CPU or a defect on the data lines. Unless the reset works, this is not likely to be a DYI repair.

Rear Speaker volume too low

Channel level output can be adjusted in the menu if you have the remote. Set the rear channel level volume higher and the fronts lower if need be, and then turn up the volume. Enjoy!

It keeps shutting off

If you have zone 2 active with the level turned up too much it will cut out the whole unit. Try disconnecting zone 2 speakers, then turn the volume level way down on zone 2 and it should stay on if that is the problem.

When I initially bough mine, I had the same problem. It wouldn't shut down, but occasional popping sound on the center speaker. Turns out the impedance on the speaker was 4 ohms, not not 8. Replaced center with an o 8ohm speaker. This receiver is not reated to run 4 ohm speakers. If I had problems with 1, I can only imagine what kind of problems could happen if all the speakers were 4-ohms.
