    Got the same problem. After turning on the receiver it goes into protect mode after 3-5 seconds. Will try to disconnect speakers and see if that helps - a loud pop comes out of one my rear channels.

    Man... I have the exact same problem. Mine works great most of the time, but at night (usually when I am using it) it starts this super-loud popping sound for a few seconds and then shuts down... Sounds like meteors hitting a tin-roof? What's up with this? Defect?

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.

How can I run a turntable through the onkyo tx-sr603x?


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

Onkyo TX-DS777 does not retain settings after power loss


No internal battery, a large "SuperCap" on the main board acts as one. Look for C8007, 0.1 F, 5.5V.

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.

Open up the receiver. Check the fuse. The fuse protects the circut board from overload.
