Power outage overnight. Now, Onkyo TX-SR603X no longer functions correctly. When Video 1 is selected, Video 2 diplays on output (TV) with no sound. When Video 2 is selected, DVD is displayed on output (TV). Very confusing. Has anyone seen this before?

Re: 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.
Testimonial: "Appreciated. I'll try to "reset" tonight."

does not sound like the fuse. its easy to check. unplug unit and remove the cowling / shroud of the unit. the internal fuse will look like a car fuse. the old round style about 1" long and 1/4" round. sounds like a bigger problem. hope this helps.
Not to be found. Your remote controls a lot of functions, and as such can be confusing to program properly. I can only suggest two things, one, sit down with pages 14-18 of your user's manual and use some patience finding how to work it. If you do not have a manual it can be found at manualslib.com and look for this search result ONKYO TX-SR603X INSTRUCTION MANUAL Pdf Download. with manualslib.com underneath. Your second option is too take it a repair shop or knowledgeable audio/video dealer and have them program it for you.
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.
