Sound cuts out Sony STR-DE675 Repair, AV reciever sound drops out 

I have a Sony STR-DA5ES that had an intermittently working front right speaker, I found the service manual and tracked down the same soldering areas as shown on your board for that speaker. The DA5ES has a separate speaker board, so the disassembly was much easier. It was hard to tell if the solder was cracked or not (I don't have a trained eye), but I resoldered the connections and reassembled the receiver. So far so good. Thanks for the video.

Many thanks! I have a DE375 that makes clicky noises and sometimes the center channel went silent. I resoldered all relay pins and it seems to work again :)

Thanks for making a short to the point video. Very efficient to learn from.

I have the SONY AV STR-DE595 with the same exact problem. I'll try that and see if it works out!

Thank you so much for your video, that fix my right front speaker to work without interruptions!

oooo yeah! thnks! :) its work on str db840

Fantastic. Centre channel went intermittent on DE685. I will get into it tomorrow.

Nice video😊

I have a similar Sony receiver from the same era (STR-DE335) I recently got it on ebay for $40. I've had it for several months, occasionally I hear something internal clicking out of nowhere (must be the relays, it looks like there are three), and sometimes the sound stops coming out of certain speakers (I have three plus a sub), giving it a whack usually makes it work again. I was kind of nervous something major was wrong with it, but if all it is is some weak solder joints that's very relieving because I really like this receiver. Should be easy to fix. Thanks for the video!

I have a mid 70s Sony SQD 2020 4 channel decoder that does the same thing on the front left channel. Could mine have the same problem?

I have the same amplifier (Sony) and I have tried to connect a car radio to it by cutting the wire that comes from the main part to the small square part which is the output for video display (where the yellow output). there were namely 3 wires, a ground, a 12 volt and a 25 volt. After I got my car radio connected to that power, it worked in the first place and it turned off afterwards. Now I have removed the radio and have bought it back in place as it was before. Now the amplifier works but there is no sound. I have measured volts on the wire that I had previously connected to the radio. it shows 9 volts on both the one that had 12 volts and the other that was on 25 volts. how should i rapier it? thank you for your time.

Hey man do you think you can help me out so I have a Sony str de697 and so the volume has to be at 30 to hear the music whys that?

hi can you help me ...i use it as aux i have front left sound is ok ...right front sound low with distoration and cut ....i change transistor shorted and resolder as your vedio show relay ...and still same ...when i change from afd to surrond or other mode i get protect mode

just checking if you might know this. I have a Sony Amplifier, type TA-FB720R must be 30 years old or older. Still works and I just use it with one of my computers. But I am getting a kind of a "rattling noise". It is not a contineous noise but I get a series of fast ticks tick-tick-tick-tick etc, maybe 20 ticks and then it stops and a bit later again. It seems some sort of discharge. Maybe the condensator? It only started with a few ticks but now it is more often and I turned it off now. Does this problem sound familiar or could it be a multitude of things? The amplifier body is grounded so it is some part in the amplifier that is causing the problem.

Thank you so much for sharing this video. I had the same issue did what you showed on your video and it worked save me from getting a new receiver $$

It is a shame that modern receivers don't have a removable panel on the underneath, it would make like so much easier for the sake of a bit of penny pinching on the manufacturers part, but of course they don't want to see products repaired, they would much rather sell you another one.

Hey I've got a Teac amplifier and recently the sound has been cutting out (and the amp makes a clicking noise when it does this), but still receives power. The only thing that appears to work is to repeatedly switch it on and off until it comes back. Any ideas what it could be?

Ok so I have same problem but not on this unit. Have no idea what I’m looking at in there so maybe I resolder everything 😂
