    Add Stereo Input To Hi-Fi (Sony SONY PMC 107L)

    Hi.
    I bought a Cheap HIFI to use as my PC output and speakers and forgot to check if it had an input. It doesn't.

    Is there any way to add a stereo input. I have a bunch of Phono sockets I am not using.
    Where in the circuit is the best place to solder the 3 stereo input wires?

    This is the model and schematics:

      i wouldnt - that will bypass the controls.
      it would be better to tap the signal from the tape or cd section so you still have use of the controls - and keep the tuner working

            Can i solder the negative wire to any suitable ground on that main board.
            Eg: On the volume control ground marked blue circle in the jpeg?

                computer should have a mixer and radio . be just like using main in on a proper amp . .
                could add pre out main in then send pre out to computer ..

                  NAD 3140 phono input mistake !!
                  by guizmo1967
                  Hello,

                  I accidently connected my aux input (TV) to phono1 and now phono1 is louder (volume higher than phono2).

                  If I don't touch the volume knob and switch my turntable to phono2, the sound is very good on both but phono2 is just lower than phono1 ???

                  Do you have any idea why ??

                  I look at the service manual and there is two 330K resistors connected to ground and to each phono inputs. Do you think that could be one of those resistors ?...

                  820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?
                  by ugamazing
                  So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

                  1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

                  2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

                  Sony CMT-SPZ90DB HiFi PSU Problem?
                  by Nevillet
                  Hi All,

                  I'm trying to repair a Sony CMT-SPZ90DB compact HiFi that includes a 3-disk CD, cassette & tuner.

                  When it's plugged into power the red LED illuminates but when the Standby1/0 button is pressed it briefly starts up with CD & cassette motors starting but then goes back into standby.

                  The power board shows signs of heat and a picture is included as is the service manual.
                  I've been doing a quick check of a some componants in the PS board and came across D602 which is open circuit.
                  Off the board it's still reads o/c.
                  ...

                  Sony STR-DH520 no optical input
                  by alfatv
                  Hi guys,
                  This is my own (actually present to gf) amp which I am not even using so much.
                  Recently started to use optical input from TV which worked great.
                  However recently the link went down.
                  Few days ago I opened it up, cleaned PCBs from dust, then came back to life.
                  But today it did the same thing again.
                  On TV when I change setting from speakers to just optical and other way around, audio comes up only for very short moment.
                  There are 2 optical inputs, both behave same way.
                  I found schematic which is attached.
                  I hope this forum experts...
