I have an Alpine CDM 7874 head unit in my car the lights have gone dim on 1 side of the faceplate. Is there some fuse I can chage to get them working again, or should I get a new faceplate?
have you checked the fuses?
it maybe a fuse check your car fuses
if in case you have a undesirable cconnection or a quick interior the wires. you additionally can want to alter the fuse for the radio/stereo on your vehicle. The fuses are oftentimes placed under the steerage column.
Dim or out completely? Most electronic faces that require lighting usually use a few LED's or smaller lights to light up the entire display. There's usually a network of clear plastic tracks running behind the buttons, the light source shows in at one end of this plastic, and the light travels along the plastic and any buttons it pass's by will light up. Sounds like one or more of the LED's burnt out and the ambient light from other LED's are the dim light you see. You could open the faceplate up, take the cover off and place the face onto the deck and power it up and check if all the LED's light up. Replacing the lights would be tricky since you'd need a surgeons hand to desoldier the LED's and then put new ones backwithout buring the circuit board :P Btw, there would be no fuse's present in the faceplate since there's nothing but buttons and the LCD in it. The fuses on the back of your headunit are for the internal amplifier. You'd know if they were blown since the unit wouldn't even come on.
Get a new faceplate. It has nothing to do with fuses, fuses blow and entire components stop working. LED lights last a very long time, but when they go bad they typically dim first, then quit.
