Question about Sony Car Audio & Video

Open Question

MX5 MK2 reg 2000. Sony CDX-C4850R CD/Radio cuts out after a short time, but the speakers are still humming. If I remove/replace the face plate and turn it on again, it works again for a while.

I have owned the car from new. It has 50k miles on it. I rarely use the radio but my son has been driving it for a 2 days a week for a couple of years and winds the volume up high. I have cleaned the contacts on the faceplate but it made no difference. It happens on CD and radio sources. Any help would be very much appreciated.

SOURCE: The radio plays the CD but the faceplate is dead

it sounds as if your i/o relay for the control face is toasted and part of the relay is welded and carboned. you will need to replace it or chances if this burnt therre may be more behind this such as the amp if equiped. gl

SOURCE: no sound

you simply have a speaker shorting in your car. Either an old speaker with a bad voice coil (short) or a speaker who's contact(s) are touching metal. This type of short or grounding will cause the internal audio amplifier to shut off to protect the radio's output circuit. To diagnose which speaker is the culprit, you'll need to disconnect all speaker leads from the radio and one by one re-connect them until the output shuts down again. The safe way to check is with a voltmeter. If you connect one side of your voltmeter to ground and test each speaker wire lead for continuity, you'll hear an audible "beep" whe you find the grounded wire/contact. A professional car audio shop can diagnose this for you if you're still having difficulty. Hope this information was helpful.

SOURCE: CDX-S2000 Volume, Source, and Mode buttons not working????

Hey jshaff, try taking off the detachable front, and you will see a reset button, press and hold in for 10 secs, this should solve your problem. if it doesn't work first time keep trying. you must have power to the head unit for this to work. you will hear the cd make a noise and that should be that, try and let me know.

Sony CDX-5005 factory installed in a Bryant boat... no out put in any mode to speakers. What replacement unit will fit and hook up to existing harness?

Any DIN style radio will fit onto the existing cut out.
Stay with Sony CDX family. The connect and color code will be the same.

Do you still has the remote control for this Sony CDX-C5005?
This remote has an "ATT" (almost like mute) //// lower left hand button.
Aim the remote to the radio and press the ATT button and see is the volume restore to normal.

I've had my Sony Xplod CDX S2010 Radio/CD player in my Jeep for years and it has all of a sudden locked up on me. The CD player will play and eject CDs, however it doesn't allow me to adjust volume or skip...

i'm not sure if there is a flexible cable that goes from the face to the motherboard. if there is, that could be the problem. it could also be a bad switch.

Sony cdx m610 resets itself at half volume

You have a shorted speaker or speaker wire. If a wire is touching metal lightly it may not have full continuity (short) and will work until more voltage (volume) is sent to the speaker and causes the short. Disconnect all speakers at the radio then turn the unit back on. Turn up the volume and see if it cuts out. If it stays on, re-connect speakers one at a time and test. Once you find the problem speaker, disconnect the wire at the speaker then test again. This will eliminate the speaker itself as the problem. Test again. If it still shorts, trace the wire from dash to speaker and look for a cut in the sheathing exposing the wire. Repair or replace the wire and you should be good to go. If the unit cuts out with all speakers disconnected, the problem is internal and will need to be serviced. Before you repair/ or replace the unit either check all the wiring and the speakers or have someone do it for you so it does not give you a repeat performance. Hope this helps.

There is a ribbon cable that tells the face what to do. You will have to take it in to get serviced as it is very hard to change. There are alot of pieces / parts inside.
