Faceplate display backlight out

My Sony car stereo's display went "dark". Since I can still (barely) read the messages, I presume that it was a broken backlight. Does anyone know how to replace the light bulb (if any?) in the faceplate? Any other possibility (e.g., power supply?) JP

Re: Faceplate display backlight out

I had the same problem. I took the faceplate apart. There are 2 LED's on each side of the LCD display on the faceplate main board that illuminate the LCD display. One of them was burnt out on mine. I replaced it with a green small LED, however the light output is not at the same level as the remaining orginal LED. The original green LED looks like a high output white LED that was covered with a thin green coat. Not sure where you can get those.

Re: Faceplate display backlight out

Your display lights are burnt out. This is a common problem. It is covered under warranty. Send it to Sony for service. Anyway, under the Sony faceplate there are two small, different colored leds which control the color. The light is aparently transfered through pieces of clear plastic (best example I can think of is the piece of plastic over the led in a household smoke alram)to most of the buttons and the backlighting. If your display has burnt out you may just be able to swap the leds for new ones. As for the intermittent green could it just be a faulty solder on the board.

Will not turn on without removing faceplate and putting it back in


Try cleaning the contacts behind the face and on the sub panel behind the face with either q-tips and rubbing alcohol or a pencil eraser. If you use a pencil eraser, make sure you brush off the debris.

How do I unlock my Kenwood KDC-MP528 car stereo


To reset the code do the following:
1) Turn on the car.2) The faceplate rotates out and the CODE - - - - prompt appears.3) Press >>' and Auto keys simultaneously on the faceplate and hold for 4 seconds. (If the faceplate rotates back into the console push on the upper left top edge of the faceplate and it will flip back around. Press the Eject button and then try it again.)4) The screen will still say CODE, but the - - - - will disappear! When this happens press the 5 key on the remote twice and it enters a K on the display on the faceplate. Hit the >>' key on the faceplate.5) Press the 2 key on the remote three times and it enters a C on the display on the faceplate. Hit the >>' key on the faceplate.6) Press the 2 key on the remote once and it enters an A on the display on the faceplate. Hit the >>' key on the faceplate.7) Press the 7 key on the remote twice and it enters an R on the display on the faceplate. Hit the >>' key on the faceplate.8) The radio goes into All Off mode and you are set! Hit the SRC button on the faceplate to select CD, Radio, etc.
For further assistance please let me know.

I hav a Sony CDX-GT65OUI that beeps when the car shuts down. I have my IPOD connected to the stereo - made sure the ipod was shut down the USB cable removed from the stereo but it still beeps. Do you...


It beeps because it is an "alarm" that sounds because you are not supposed to leave the faceplate in the car when you get out. I read this in the manual

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 !

Accidently removed the tiny screws behind faceplate


It could just be a plastic clip that broke.Most of the car stereo's ive taken apart only have a thin ribbon of wires that run into the contacts that your face plate connects to.If you actually took screws out of the faceplate then id put them back in and put it back into your stereo and see if it illuminates properly,if it does not then id search on E-BAY or contact pioneer and buy a replacement but most the time it would be cheaper to just buy new stereo.You might want to be more specific with the area you took screws out of,the way im reading it sounds like you unscrewed the screws in the face dock, not the faceplate.Hope this helps.

It sounds like the mini-bulbs burnt out. Any good repair shop will have them in stock and it shouldn't cost too much. We charge around $35-$55 to do it.

Faceplate not responding / acting very weirdly


Sounds like a bad connection with the faceplate and the multi connector that the faceplate mates with when closed. check for dirt and bent pins on both connectors. Luck
