Question about Sony CDX-M8815X CD Player

1 Answer

Illumination not working when faceplate is open.

I notice that my illumination is not on when the faceplate is open but the unit still works. I also closed the face plate and same result. this is while driving. Got home and turned off the car and turn the key back on to ACC position and noticed the faceplace briefly light up then turn off when fully opened. I closed and the illumination stayed off but the unit was still playing. I cannot see display status. So, I tried another approach. This time I set the unit so the face would stay closed. I turned on the car key to the ACC position and the system turned on with illumination. I was then able to see the display. Using the remote, I openned the face plate again to change the cd and the unit illumination turn off again. I inserted another cd and it played.

    Marv,

    thank you for your response. I suspeced that it was some sort of connection problem with the lighting. I just wasn't sure. Your input is very helpful. I'm pretty handy although not an electronics expert, I can probably figure it out. I was having trouble locating the part in the Sony site. Would you ahve a part number available. The only other Sony site was a B2B (business to buisness) registry for ordering parts.

    Again, thank you.

Wire braid out to the faceplate has got a parcially broken wire on it. Sony referes to it as a flexible circuit board. Part can be purchased from sony directly, an on a one to 10 scale to replace about a five.But it does involve taking your radio apart. So if you are handy at electronics. you can look it over. If you have doubts let a professional do it.

    Just call Sony and provide them with the model number and what it is. Remember flexible circuit board is what Sony calls it. But to me it looks like a flat wire braid.

What is the fuse number for the dashboard lights on a 2007 Ford Focus 3 door hatchback?


Principles of Operation
The instrument cluster and panel illumination consists of dimmable and non-dimmable illumination components. The dimmable illumination is controlled by the instrument panel dimmer switch, which allows the brightness level of the backlights to be adjusted to the customer preferences. With the parking lamps ON, the instrument panel dimmer switch uses electronic circuitry to provide a variable pulse width modulated (PWM) output to the instrument panel and all applicable switches depending on the driver-controlled level of intensity. The headlamp switch backlighting consists of 2 constantly illuminated LED bulbs that are powered by separate circuits. Battery voltage is supplied to the first bulb when the ignition switch is in the RUN position. Battery voltage is supplied to the second bulb with the parking lamps ON. The non-dimmable illumination allows for full intensity dependant on the ignition switch position.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

I have an 06 ford explorer the instrument cluster lights and radio lights don't work


Are these the lights you are talking about ?
Instrument Cluster and Panel Illumination The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the headlamp switch is in either the PARKING LAMPS ON or HEADLAMPS ON position. The level of intensity is adjustable by rotating the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.
Fixed Backlighting When the accessory delay relay is energized, switched voltage is supplied to the non-dimmable components and switches.
Dimmable Backlighting When the parking lamps or the headlamps are in the ON position the smart junction box (SJB) monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable components and switches based on input received from the instrument panel dimmer switch. The SJB also sends a message over the controller area network (CAN) to the audio unit, and the instrument cluster to indicate the backlighting intensity level.
If you don't know about PWM an smart junction box your better off taking your vehicle to a quailified repair shop ! You don't the diagnostic tools or technical information . May have DTC'S - diagnostic trouble codes stored in the SJB (computer ). Do you know where SJB is located ?

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
  • check that the program card is correctly installed.
  • check the connections to the vehicle.
  • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
  • CAN circuits fault; all electronic control units no response/not equipped, refer to Section 418-00 .
  • No response/not equipped for SJB, refer to Section 419-10 .
  • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the SJB.
  1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index.

My pioneer deh 9300 comes on but the faceplate wont do anything. What could it be?


The first thing to do is to clean the contact points on the faceplate and the
chassis. Use a toothbrush, if there's corrosion, or even dust build up it can have an effect on functionality. If it's still out, check the illumination fuse behind the unit. My memory is a little vague however I think the illumination lead is orange on Pioneer. If it's still inop, slide the unit out and take it to a local car audio shop to be bench tested. Leave the harness in the car. If they sell pioneer, they will have one to use. Hope this helps

Got power to cd but no display


One idea that comes to mind is,if I remmeber correctly, that model has a removeable faceplate, try this, remove the faceplate,take some denatured alcohol on a Q-tip,clean the electric contacts on the back of the faceplate and also on the front of the deck where they mate together repeatedly for about 4 to 6 times letting them dry between each time that you swab them clean, then replace the faceplate onto the deck being sure that you are seatting the faceplate completely and properly.
This has worked for me sometimes and sometimes not, its worth a try.
Good Luck !

KDC MP242 faceplate will not light. I have the unit run directly through the car vehicle battery for power. The CD player will accept and eject a disk, so I know the unit is getting power. However, I...


Im not sure if this is gonna fix your problem because im not exactly sure what you mean when you say you ran the player directly to the battery....but if the faceplate is not lighting up then it is possible that you may have not connected some of the wires properly. Some head units come with illumination wires which I believe are usually orange and that could fix the problem of the faceplate not lighting up....I hope that you are not actually running it straight to your battery..like under your hood, straight to your battery. I would imagine that you have purchased the proper wire harness and have matched the wires properly in the dash to the radio harness. If you do not have all of the wires hooked up and the harness plugged in to the radio and ready to go like your gonna put it in the dash to bolt it in then do that. Hook everything up properly with the wires and the harness so its like its ready to be bolted in and then test it...if the faceplate is still not lighting up then you may need to bring it somewhere to have it done professionally or if you are confident you are doing everything properly then it could be a faulty screen. I can add that I have installed many radios and had have lots that I have not needed a use of that orange illumination wire for.....its pretty straight forward just matching the colors and connecting them...but if you have never done it then you should probably take it somewhere, just not sure if you have ever done it before. Hope this was helpful to you.. :) Good Luck!

1995 subaru legacy l the dashboard lights are not working


  • Check fuse #9 at in car fuse panel
  • Check Illumination CTRL Module for melt-down
  • Check that Tail and Illumination relay is fully seated, top center of in-car fuse panel.
The relay is most likely the cause.

Replacing The Cobra 29 Nightwatch Illumination Panel


YOU CAN ORDER THAT PART FROM COBRA ELECTRONICS ON THE INTERNET YOU HAVE TO REMOVE THE FACEPLATE AND UN HOOK THE DRIVET INSIDE THE RADIO IT LOOKS LIKE A SMALL RIBBON CABLE THAT GOES TO THE FACEPLATE. SOME TIMES THE DRIVER ITSELF IS THE PROBLEM. MANY SHOPS JUST DO NOT WANT TO FIX THEM BUT I DO.

No back light on display


I know that most Clarions have an "illumination" wire usually orange and or orange/white. If the unit only has one, then most likely it is for a "dimmer circuit" and not atraight illumination. Let me know. If by putting power on tat orange wire does not do it, then you have a bad "bulb" in the faceplate.

I just installed a Clarion max385vd. When we turn the headlights on, the buttons and screen illumination on the head unit keep flashing from dim to bright. Everything else is working perfect.


illumination wire does not need to be installed on this model. depending on your car, it may use odd voltage for the dash lights. Clip and tape off the illumination wire going to the harness.
