    Sony str-dn850 home receiver no left channel.

    Ok start off by saying I have some tv repair but not much on the receiver end.
    Picked up a Sony str-dn850 home receiver when I first plugged it in powered it up it came on and the system check relay clicked and about 3 seconds later it went into protection mode.
    I powered it off and on. Comes on no problem.
    Hooked up speakers and it started to pop and crackle but the volume was all the way down.. and I was only getting that sound out of the left channel. Right channel had no sound.. but every time I turn the volume up it has a smell crackling sound on ever volume number... and no other channels or sound was working but front speaker

    Just tried it again and I only get sound from the right speakers but it still crackling and very very low music.(barely hear it)

      Sony is known for crap solder joints in the amplifier section, reflow all the joints on the transisters and on all the bigger components and see if that fixes your problem.. I love Sony home theater receivers and car stereos, I think they sound better than most, but every Sony receiver I've owned I've had to reflow solder joints. They become cracked and the symptoms are pretty much what your describing

          2 years ago but a classic protect relay problem of dirty contacts . more power more sparks more current gets through .

              Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul
              by karatzdi
              Hello,

              I know some might say... just buy another one. Sell it as parts..!

              So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
              Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

              Spent some time downloading the Service...

              RCA WHP141 wireless headphones wired up
              by momaka
              OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…

              Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.

              As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right! So let’s take...

              Onkyo TX-SR805 noise in one channel
              by MegaZAC
              Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

              Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

              There's some logic behind it. As soon as I select an input I get only left...

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
