When I hit the reset button and then turn the player on, if i turn the volume control right away I get the volume display to come up for a sec then it goes away, but the volume doesnt change and it wont come back up. I have checked all my solders and they seem good. I cannot figure out why the volume wont work. Any ideas?

    Thanks,

    Here is a thought, I have not done this but...
    On my head unit, if I remove the face (controller) there are some switches that are needed to be pushed in for the head unit to operate. And I'm not talking about the where the metal contacts need to meet up. Just a button or a switch...
    take a look

    Have you traced the connections to make sure you don't have any shorts?

    Also what BossTone74 said maybe true, it could be that the volume is physical, but you should have noticed that.

    Thanks guys, but the volume is built into the circuitry of the board connecting the face to the HU. There is only one button that needs to be pressed in and thats the one that tells the cd player if the face is connected or not.

    I have issolated the problem to just the HU side b/c i took another face (exact same) and hooked it up and the same prob. I checked all wires for shorts and there are none.

    After going back and rechecking the solders I found one to be loose, like the wire is connected to the pin, but the pin can move side to side in the board. I don't think it is made to do that. It may be a loose connection which is giving the volume not enough juice or something.

    I've been working on it for bout 7 hrs straight trying to figure out what is wrong!!

    Goodluck and let us know if you are able to fix it and identify the problem.

    I'm going to give this a shot in the Focus, as there is no real place to mount the headunit...

    if the volume is controllled by a variable resistor pot in the face theres a chance the long wire run is adding to the resistance enough to affect the volume control....IF this is the case the only solution would be using wire with less resistance on that circuit(if you caneven isolate it) or shorter extention??

    Hey, I love this idea and I'm gonna deffinately have a go at this, I have a Pioneer P6400R head unit, and I have a spare back since the plastic surround has been ripped off it.. So i have a head unit to test with before i shag my actual stereo..

    Ugh, having the worst luck trying this with an Alpine CDA-9855. I must've soldered it 5 times now, and all I get is working buttons, some lights, but no screen. Using Cat-5 like others, and using a volt meter to ensure everything's connected ok, no crossed cables, double-checked wires... so frustrated.

    turns out that the cat5 coupler was KILLING the coltage, there was more than a 90% drop through that coupler!. so now its soldered straight to the HU. I dont plan on using the cd player so its not a big loss. I will post pictures later.
    I'm a little new with the electronics stuff... I'm using a volt meter to measure resistance between the contacts over the wire to ensure each contact is connected. Is this what you're talking about, or are you actually measuring voltage? I'm also using cat-5 couplers, but since the resistance measures the same with them on/off, I didn't think they were affecting anything.
