Question about Sony XR-CA370 Cassette Player

1 Answer

Radio not working

I've just got a new car and attached the XR-CA370 to power - but I can not get any lights or anything on the display.

I have followed the connection guide from SONY and connected the black cable to earth and the red and yellow to the 12V+.
I have tried just the red to 12V+ and press reset, nothing.
Just the yellow to 12V+ and press reset, nothing.
AND both red and yellow to the 12V+ and press reset - NOTHING!

Any ideas / help / advice?
PLEASE!

    I had already checked the power supply, earth and fuses. In fact I even plugged in a cheap radio and that worked fine. My nice SONY XR-CA370 was working fine in my previous car and I thought I must have wired it up wrong or had to do something to get it powered up (I don’t think it had a code?).


    All I’ve done so far is connect the red and yellow cables to a good battery (+ve) and the black cable to the –ve. I then pressed the reset button, as per instruction manual, and attached the front panel – no display and no lights. I cleaned the contact on the panel and repeated the above steps - nothing.
    I tried pressing the OFF and indeed every other button, several times – no display at all.



    I was rather surprised to get a voltage from the yellow cable and earth – with no car battery anywhere near. I assume it has a battery (small black square on the circuit board?) or capacitor somewhere. I have taken the radio to bits and cannot see any obvious damaged capacitors, shorted resistors or bad solder joints.



    I was just hopping that someone would say “press X” or attach cable Y, but I am beginning to agree that the radio has died. It was kept in a box for a year or so between cars and now it seems I may have to burry the poor little thing I that box.



    Thanks for your help Bear40.

    Thanks again Bear40.



    I do not remember that this radio had a code, but you could be right. Nothing in the manual?

    Do you have any idea how I go about entering the code (if I ever find it)?

    I've had radios with codes before but they always displayed CODE or something on the screen, this one is just totally blank,



    Thanks for you help but I think this one is going in the bin!

Have you made sure your power source has power?
Next check your inline fuse if it has one.
Make sure you do have a good ground.
If none of these solutions work you most likely have a bad system.

    It has a removable face if you removed it before disconnecting the power you should have to enter a code to get it to work again.
    It is part of the security feature of the unit to keep people from stealing your deck and placing a different face on it.

    you know you are right you don't have anything at all I would say your radio is gone.

Which wires to use as positive &negative in sony xr-4807 car tape


The red wire is for ignition switch power, the yellow is for constant battery, (station and other settings memory). The black is for ground. I got a power converter, 120v ac to 12v dc, from Radio Shack, but I'm not sure they still sell them.

Have recently installed unit into my car but when i have set it up ie radio stations into the memory, when the car is turned off then back on it deletes all the information ?


Somewhere along the line you are not receiving a constant power supply to the head-unit. When you turn the key off it is cutting the power to the unit like it is being completely unplugged. Thus the reason it wont remember anything.

It sounds like they messed up your installation. You can confirm their work by verifying that each wire was attached properly.

Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Click on this link for a PDF of the installation instructions of the radio (If you don't have the installation guide that came with the radio).

Illumination is the grey wire from the car to the orange with white stripe from the radio.

I suspect that the yellow wire from the car is not connected properly. When the orange wire (constant power from the car) is attached, but not the yellow wire you can insert and eject cds, but it will not turn on. Constant power is used for maintaining the clock and preset radio stations.

If everything looks correct, I would take your car back to the installer and have them correct the issue.

Panasonic CQ-C7103U having faceplate attachment issues.


You can order a new faceplate from Panasonic, if that is the problem. (You may find one on ebay, too?) Carefully check the connection before spending anything, as I wouldn't want to suggest spending on something that isn't broken. If you have electronic skills, check the internal connections from the jack to the internal board and every other connection. Also look for cracks in the board. If found, a light coat of solder can fix that up fairly well, and not cost anything.

Of course, this is all a guess, and I would verify everything yourself before doing anything. Good Luck.
