Question about Sony STR-DE475 Receiver

1 Answer

Center speaker channel

The center speaker channel turns off after a short time as though the current limiter has kicked in. I have tried the speaker by using a different one but no change.
All other functions seem to work ok

Thankyou

HI, I have Receiver Marrantz SR- 5005, the center chanel does not work, please tell me what happened and solution to fix the problem. Thanks


Get the manual and open it up to the part where speakers are defined, then test it/them with tones. Try swapping a different speaker into the center if the current center channel speaker still doesn't work.

Web search "Marantz SR-5005 manual" (note the spelling)

PROTECT is flashing on our Sony Digital Audio/Video Control Center


PROTECT means the receiver is automatically powering down to protect it's amplifiers. Top reasons are overheating, which can be caused by poor ventilation, covering vent holes, excessive volumes for long periods of time, or it's actually just that hot in the room, which, with the current weather, I've encountered in clients homes before. The other option, and just as common if not more so, is that the speaker wire outputs are shorted out and are causing the amp to turn off. The easiest way to test this is unplug all of the speakers and turn it back on. If it still says protect, then it's either too hot or there is a physical problem with the protection circuit and needs to be serviced (this would be a good time to kick yourself for buying a sony receiver). If it DOES power on, plug in the speakers one by one, and if the amp goes into protect mode as soon as you plug in a speaker, it's an issue with that one. Check for short circuits in the line (kinks, frayed ends, staples going clear through the wire, etc). If the wire looks good, try putting a different speaker at the end. If a different speaker works, then the speaker is blown, which gives 0 continuity, and the receiver is correctly protecting itself from the high impedance load. Change the speaker.

The DDT light on one channel stays on,but I can't find a reason why? What can I do?


Disconnect the speaker wiring and speaker on the bad channel. Turn the level control(s) all the way counterclockwise and turn the amp on. If your DDT (limiting) light remains lit, it's time for a visit to your nearest certified Peavey service center....G.

Center channel is not working . Surround sound from center channel not working. I have found two fuses blown and replaced . when unit turned back on o try they blew again


First make sure the centre speaker is not shorted, try a different speaker and new fuses. If this fails and you have electronics knowledge here is the link to the service manual...

The driver or power output device (FET or Transistor) is probably shorted if the speaker is not shorted.

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.

Onkyo TX-SR500 Dolby Digital problem


I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps.
