Question about Sony STR-DE545 Receiver

2 Answers

Center speaker The center speaker plays for awhile and then it goes out. All the other speakers work so I have to switch to AFD mode or 2 channel mode. I have checked the connections in the back and everything is in tack. When I turn it on again in V multi semi or surround sound, the center speakers works again but for a while. What is wrong? I can hear it go out similar to the sound when I turn the receiver on or off. Thanks in advance for your help. Corey

    Your comment was very helpful. It is such a shame that this receiver has this problem because it played so well. It'll probably cost between $200 & $300 to fix it. I've checked one repair place and it will cost $85 dollars just for them to diagnose the problem. I think that Sony should have a recall for this receiver or have their customers send it out to be fixed for free. I'll send them an e-mail to let them know of this flawed product.

    I'm having the exact same problem with my Sony receiver model STR-SE501. I bought it a few years ago and it's worked fine up until a couple weeks ago. Now it's VERY annoying and the center speaker goes in and out at will. I took the cover off to see if I noticed any obvious loose connections, but couldn't tell. I also tried reconnecting all of the speaker wires and replacing the speaker wire to the center speaker, to no avail. Any assistance anyone has would be greatly appreciated before I spend money on other receiver. Thanks!

Yes, this is a symptom of bad solder, especially the Blue Relay contacts. Re-soldering will fix it, I did it for mine.

Mine is doing the same thing, you can hear a click sound and the channel will die. I think it is a relay or a shunt that trips when something goes wrong with that amp. I dont think it is worth repairing as there are some nice receivers out there for cheap. Maybe just a cold solder joint somewhere? Anyone know where and Ill dive in and resolder and post the results.

Why does only center channel speaker work?


Try running a sound test. You should have a test mode that will play a sound through each speaker to see if you have them hooked up correctly. If you still only hear it from the center, unhook the center and connect it to another speaker output, say right front. Run the test again. If you hear something from that center speaker, its the speakers. If not, try each speaker output to make sure the results are the same. If so, you may have an internal board problem.
Good Luck!

Rear speakers are dead, never got them to work. Changed front to back and rears work so speakers and wireing are good. Is it possible that because I did not hook up a center speaker this is the problem?


if its a 5.1 channels it means 2 front speakers,2 rear speakers or either the center speaker or the subwoofer.try to hook up either center speaker or subwoofer.

Denon AVR-682 center channel has no output


You may have had the receiver set to "Stereo" mode, or Analog instead of "Digital" or "Auto" (automatically switches to digital when it detects a signal) modes. Also, setting it to "Direct" (2-channel from an analog source) could result in loss of center channel. Or your Surround Parameter dial (on the higher-end Denons, at least) could be set to a 2-channel mode.
Finally, if your digital inputs are incorrectly assigned (e.g., COAX1 instead of OPT1, or OPT2 instead of OPT1) for that source, the receiver will use the Analog signal which is stereo-only. You could get a center channel via Dolby Pro Logic II but it would be a "matrixed" signal, not the "real" center channel you could get via digital input using Dolby Digital or DTS.
(If all else fails, re-check your center channel speaker wire connections. It's very unlikely, but also possible, that either the receiver center channel amp or the speaker has failed.)

B speaker setup problem


Why don't you set it Zone 2 then you could listen to the radio outside and still watch tv inside. You can turn it on and off just like a and b speakers.

Center speaker


When you turn on zone 2 you are in stereo mode. The center speaker and the rear speakers will not function in stereo mode.

Try turning on zone 2 and then switch the surround mode after that and see if it helps. If it turns the zone 2 speakers off when you do that, then your unit does not support what you want it to do. Center speakers only work in listening modes other than stereo.

Most A/V receivers are designed for watching movies and they did not take this use into consideration because zone 2 would normally be in another room such as the way you have yours set up. If somebody is watching a movie in one room they would not need to hear it in another room. You would think that the designers, who are very talented to be able to come up with these type of units, would have just a little more imagination on how people would be using the equipment. Go figure!

If your receiver has a 5 or 7 channel stereo mode, it may work then. You can try, but I don't think it will help.

I have even seen some receivers that have the center channel amp being used for the zone 2 output as well. It just switches what speaker output jacks it goes to with a couple of relays which makes it impossible to use the center and zone 2 at the same time.

I guess they are just being cheap by not putting another output channel in the unit and sharing the one they have.

Why would anybody want to use the center and the zone 2 at the same time???? Sad, isn't it.

Hard to believe that such a nice receiver would have such a rediculous limit designed right into it. But they really do design them like that.

Let me know if you need more help.

Center speaker not working


Yes Mark, You have a problem with a componet with that center channel. If your not a tech, dont have a schematic, or dont have any training in troubleshooting solid state electronics, unhook everythuing and take it into a repair senter for an estimate, as unless you know how to chech the parts you can cause more damage to the unit as it takes one slip and boom, all gone. Good Luck
