Question about Sony STR-DE310

One channel got quiet in the A speakers

The receiver worked fine for years for my son. He gave it to me about a year ago. It was fine for a long time. Now the right channel is very quiet. We tested the speakers by moving them around and they are fine. It works fine using the B speakers only...perfect tone. Our speakers are old retro style, but I don't know what kind they are. I am thinking I need to open them up and find out what ohm they are. (?) Or, can you think of other ways I need to check it? are there fuses?

My problem is similar and i realize it's from these two tall cylinders and have become somewhat corroded. If i move them in a certain way the right speaker will come back on. I can't find a free REPAIR manual to tell what those cylinders are nor do I know if i can replace them.

Try using the ground from speaker A TO SPEAKER B..which meaning ground your speakers on B jacks only.

Determine if an analog receiver has blown a channel


When you need to replace the output transistors, do them both at the same time with a matched pair. That way you won't unbalance the power supply and will be assured of the same power out is available on both channels.

10 years and first problem to repair. When you turn on and select DVD or any other selection a very loud cracking noise comes through right speaker only. So loud (with volume tuned off too) that I fear...


I think your receiver is damaged.

Try this.

Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right"

Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly.

Disconnect both left and right speakers.

Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on.

IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine.

Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on.

IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver.

If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

Hitachi sr 2000 right speaker interference and no sound


This should be a relatively simple repair. The outputs for the right side could be out, but more likely, the switches and controls may need a good cleaning. Typically you can expect a labor rate in the $80-$100 range. If the channel is out, the parts cost could be between $15-$40.

If you can indicate your location, I may be able to suggest a shop.

Thanks,
Dan

My very old Denon AV Receiver (DRA-55V) works fine except that one of the channels sounds 'gated' or thuddy and staticy...music is heard (in all sets of speakers and headphones) but quality in one channel...


check your speaker A - B channel push-button switchces. They tend to get worn and contacts internally corroded after all these years <!-- from fixya rte -->

Quiet front R channel on Sony


Does problem persist when you connect other speaker to front right channel? (i.e. when you connect your FL speaker to FR and vice versa)?

Problem on Yamaha RX -V 800


check to see if there are any speaker wires that are touching each other near the connections. i had this happen on an onkyo receiver and found it was a purposeful feature intended to keep you from shorting out the receiver. if the + and - speaker wires touch (at the receiver posts or the speaker posts) this can happen.
