Question about Sony STR-DE475 Receiver

2 Answers

Sony, STR-DE475, Left Channel out, sort of. Guidance from the pros.

1. The reciever was bought in U.S., I live in the U.S.
2. My Reciever Model is Sony-STR-DE475
3. I'm using Monster RCA Cables in all connections
4. I'm only using 2channel speakers.

I've been having this problem for years now, for some reason the left speaker will cut out and the right speaker will keep functioning normally, but by letting the system run the left speaker will produce audio again.
Now when the left speaker cuts out I did some checking with the RCA connections and they are all on tight and snug. When I was checking the cables I noticed that when pushing in the cables a little bit more the sound returned. But by pushing in the cables abit more I was also pushing in the White & Red connection itself. And its like that with the DVD, TV, CD, Video, & MD/Tape settings. ~Theres basically no steady stream of sound coming from the left speaker.

So my 1st-question is, would there be a soldering problem inside the amplifier with those particular connections?
2nd question is, how can I activate the blue light on the reciever? I think it looks cool.

Any help much appreciated, I'm a seasoned DIY so I'm not afraid to learn something new. I actually have a spare model and its been taken care of as long as I've owend it and it has the same problem.

1 more thing I would like to know is all of sony's bottom line products this poorly manufactured or is it something that I've over looked.
Heres one last curve ball, When using these monster cables, I have to put some pressure on these things in order for it to fit, in essence I'm putting about 15lbs of pressure maybe a tad bit more for these things to fit on correctly, Is This Normal?

Thanks for the tip, but I just donated it to a recycling place that takes electronics, I can write it off on my taxes.

My 2nd XBOX 360 just took a dive a second time and I'm not getting another one of those machines. I don't understand why companies make junk. I'm tired of fixing **** that I buy that's not even a year old.

Just plain sick of it, luckily I found someone who will buy my broken 360 even though that was disclosed.

Thanx for your help even though it took a while for someone to respond.

I am not sure if this will help, however a thought comes to mind. If you have not already switch the speakers, left to the right side lead to be certain the speaker hasn't got a bad solder or something loose. Otherwise, I have seen new products come out of the box DOA many times, all makes and models too. So rest asured that your sony isn"t necessarily a junk model, but may have a bad output for the left side. I have changed these out on a pioneer before for about $12 w/ shipping for parts, that was buying 2 parts I thot I needed and ended up only using one.
If you can solder, take the housing off the receiver and search for anything that A: smells burnt & B: looks burnt.

Hope I have given you somewhere to go from where you were at least, Good Luck!

No reset will help this. The problem is an internal short most likely in in one of the amp circuits. This is a relatively simple repair for a service shop. Expect a parts cost in the $40 range. Add in the local labor rate for the total repair cost.

Hook up problems

either cut an rca cable and splice it to the speaker wires (not easy because the rca cable is coax type or buy rca ends from radio shack and do a little soldering

My reciever doesnt power on

Hello, Drewske! I have ONE question: WHAT HAPPENS WHEN YOU DISCONNECT ALL OF THE SPEAKERS? DOES it turn on? Drew, IF it turns-on with no speakers attached, then 1) you have a problem with one or more of your speakers [UNLIKELY] or 2) you have a short in one (or more) of the speaker wires (LIKELY). Try this first, then let us know what happens.
