Onkyo tx nr676 was working last night with my Samsung tv and now nothing the tv does not see the receiver. When I switch the cable to my Xbox it comes up

Hello, Since the TX-SR502 does not have HDMI inputs you need to connect the HDMI from the XBox 360 to the TV. You can connect an optical cable from the XBox to the receiver if the XBox has an optical output. If not you can connect the optical out from the TV to the receiver. Connect to the optical #2 port on the receiver and press the video 2 button. You should have audio. Thank you, Onkyo USA

You said you tried hooking the HDMI up directly from the TV to each component, and that worked. How is it usually hooked up - through some kind of switch? I'm not completely understanding your setup here.

Hello, I am sorry about your issue. It sounds like your receiver needs to be serviced. Thank you, Onkyo USA

Hello, I am sorry about your issue. How long are the cables. From the source to the receiver and the receiver to the TV. Thank you, CB

Does it have a cooling fan? if it does, then check its actually working. Protecton circuit maybe cutting in.

If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

Hello, how long is the cable from the receiver to the TV? Thank you, Onkyo USA

Overview: I?m writing this report to provide insight into a common Okyo issue. When my Onkyo receiver began to malfunction my first response was to search the web for answers. What I fond was conflicting information. While all system issue may be unique, I hope this report shed some light on the subject. System Breakdown: Receiver: Onkyo TX-SR606 7.1 Channel Home Theater Receiver (Black) TV: Samsung - LN52A750 - 52" LCD TV - 1080p Broadcast: Comcast Component 1: XBOX 360 Elite Component 2: PS3 120GB Cables: Mediabridge Ultra Series - 10ft High Speed HDMI Cable - Version 1.3 Category 2 - 1080p - Blu-Ray - PS3 - W/ Nylon Sleeve Issue: When I first setup my Onkyo receiver it worked perfectly. Over time, my TV would display ?Searching for Signal?. After about a few minutes the receiver would detect the XBOX 360 and work fine. At first it was no big deal until the problem progressed. The receiver began to take longer and longer to detect the signal from the XBOX 360. Finally it would take up to 30 minutes or would not detect a signal at all. Finally I went through the process of changing out the HDMI cables and switching ports. This did not work, so I call Onkyo. They walked me through a reset process that did not work. Finally they recommended that I take it to an approved Onkyo repair shop. Lucky for me there is a repair shop in the suburbs of Chicago about an hours drive from my location. There are not many approved Onkyo repair shops. Most people would have to ship their receiver to another state. I took the receiver to the repair shop. They seem to have a nice little scam going on? Here is the scam.. They tell you there is a 3 to 4 week wait time (or longer) until they can even look at your receiver! BUT, if you want to put it on the ?Priority List? you can pay a $30 non refundable fee not covered by your warranty. Then you would only have to wait about a week. Tell me, who would not op for the priority list when your entire entertainment system is managed by the receiver?!?!? So I payed the $30. About 4 days later I get a call from the repairman. He says, all the HDMI ports work but they don?t have an XBOX 360 to hook it up to. So he can?t validate the problem. After arguing with him for an hour and listening to him cry about how crapy Onkyo receivers are and how hard the company is to work with, he agreed to do some research into the problem. I told him many times, simply look on the internet many people are having the same problem. Onkyo has to know something about this. Finally about a week later I get a call from the repair guy. He says he thinks he knows what the problem is. He has to order some capacitors and I could pay $45 for priority shipping. Umm wait one minute, I already paid $30 for priority service now you want me to pay more for shipping? No thank you! Over time I simply rewired my system to work without the receiver and to tell you the truth I almost forgot about the receiver. Finally I got a call from the repair shop about 2 months later saying I could come pick up my receiver. I talked to the repairman. He said the following? Solution: There are 4 capacitors that malfunction over time. It?s a common problem with Onkyo receivers. When the capacitors begin to malfunction you get intermittent signal response until it does not work. He could not explain why the cable still worked (everything was hooked up with HDMI cables). If you are experiencing this problem. I hope this helps save some time switching out cables and guessing why your system is not working. - Antious

easiest fix is to take all hdmi straight to tv. then come out of tv with optical cable to your receiver. that way what ever your watching will automatically be sent to the receiver thru optical. you even will get dolby dig. also you can have audio from your tv when you dont want to use your surround. keeps receiver on one input also.

Have you made sure the receiver's INPUT SELECTOR is set to "Video 2"? I know it seems like a stupid question, but worth mentioning as many folks would set the receiver on TV, which would not work unless the signal was also plugged into a "TV input" in back of the receiver. If your setting is correct, try running the TV cable sound temporarily into the receiver's DVD input, which we know does work. If you still don't get cable TV sound when the receiver is set to "DVD", then you have a problem with the TV cable audio portion. Most receivers would fail completely, rather than have only one input fail, so my guess is that there is a hookup or switching error somewhere.
