Onkyo TX-SR304 Receiver - Answered Questions & Fixed issues

Hello, I am sorry for your issue. The audio inputs should not matter. It sounds like those inputs do have a problem. Please contact Onkyo at 800-2291687 option #3 so that we can troubleshoot with you and provide options. Thank you, Onkyo USA

Your (5.1) receiver supports just 6 speakers. Left, Center, Right, Left Surround, Right Surround and Subwoofer. http://redirect.onkyousa.com/redirect.cfm?type=own_manuals&file=TX-SR304_En_0124.pdf

you get better play back using an analog input like tape. the sound is true to form and better vocals and bass response.

Most new recievers don't have a "phono" input. If your record player is an older kind without a built in preamp, you will need to purchase a Phono pre-amp (about $25) and then you can use any input you wish.

It may be the surround mode you are in. Some modes do not use the center channel. Try changing to a pro logic mode, these will almost always use the center

1) Tap AUX2) Press & Hold Setup (1 then 2 blinks)3) Enter 30842 or 0842 (The remote should blink twice)4) Press & Hold Setup (1 then 2 blinks)5) Enter 994 (2 blinks)6) Tap Setup (1 blink)7) Enter "00051" (1 blink per number)8) Tap Power (not All On, just "power") (The remote should blink twice)9) Tap AUX10) Press & Hold Setup (1 then 2 blinks)11) Enter 30135 or 0135

I was having a similar problem and I found that the positive and negative speaker wires were touching on the speaker connections made in the receiver.

Here is the pdf http://63.148.251.135/redirect_service.cfm?type=own_manuals&file=TX-SR304_En_0124.pdf . I found it on Onkyo's support page http://www.onkyousa.com/download/own_manuals.cfm?cat=Receiver

Check the impedance of your speakers. It sounds like the amp is getting overloaded and shutting down either for over current or over heating.
Most common issue is a partially blown speaker or crossover.
Sometimes it's just a rogue strand of wire, and reconnecting everything fixes it.
But measure the impedance on all the speakers anyways!

The pecking order for output video to your monitor forbids a lower quality video (composite (Yellow) being up-ticked to anything higher (your component out) (Page23).

The wii would be visible on the Monitor Out composite output (Page 24) to the TV.

Your Onkyo TX-SR304 receivers remote (RC-645S) is not capable of controlling devices by other manufacturers. It controls only Onkyo devices.
Other Onkyo remotes do have universal remote functionality and you can download Onkyo remote codes here.

I hope that helps.

most of the time this is an over heating problem with the unit. Make sure that it has proper ventalation around it. It could also mean that the fan is shot on the unit . You could try using a can of compressed air in it to free up some of the dust that has accumalated inside of the unit. Hope this helps

The only possibility that comes to mind is that it may be causing a short somehow when the carousel gets to that position, maybe a broken solder joint. Another possibility is that there may be a foreign object stuck inside the player such as another disc that lost it's position.

i think ur unit deposits humidity . . try to clean it up with smooth paint brush over the boards and connectors . . better yet spray some contact cleaners i think this will do . . . otherwise resolder is needed . .

Make sure you have the sub connected to the proper output on the receiver and no connections are damaged.
Then check the gain/level control for the sub. on the receiver...turn it up if it's down.
Make sure that in speaker setup, that you have the selection for a sub turned on.

Not sure if this helps, but I just called Onkyo with a request for codes for the SR304. They said the only codes they have are for THEIR remote. Maybe they will work with yours. Here they are:
0276 0476 0810 1187 1376.
I tried these in the Comcast remote (adding a 3 in front of the numbers) but that didn't work. Still trying to get my Comcast remote to program the Onkyo SR304 adequately, since their published codes only partially work.

I know nothing about tivo but dvd player might need to be on bitstream to pick it up.I have to change mine when listening to music. hope this might help.

The default assignments for the digital INPUTs to Source names are:

OPT1= Video2
OPT2= CD.

If you have never changed them you should be able to select the PS3 by choosing Video2 and the 360 by choosing CD.

Or you could go into the setup routine on Page 33 of the manual and assign each digital input to a different 'function' that works better for you.

By the way, if you have the choice of coaxial vs optical cables on a given device the cheaper, longer and least sensitive-to-dirt-and-damage choice is coaxial - plain RCA cables. You can even extend them with Male-Female extender cables or split them with Y-cables for sharing one port with two devices or one device feeding two other devices (example: Cable Box-to-TV-and-Receiver). Just don't have two sources feeding one input turned on at the same time or they'll interfere with each other. Try that with optical cables.
