    Hi there,

    I was putting a new shell on my Kyocera KE433 and have lost the microphone at the bottom. It seems there is a piece that should go between the green circle containing the speaker and the board inside. I can't find it anywhere, so I'm guessing it jumped out and ran away. As a result, I can make calls and hear people I call, but they cannot hear me. I can hear and talk to them fine with a headset.

    I'd love it if someone could confirm that yes, there should be a piece here. And if so, I'm looking for a dead KE433 or otherwise cheap one just for that one piece. Can anyone give me a hand?

    Thanks a bunch!

    Yes there is a piece that goes there. Did you look in the spot on your old faceplate. I lost mine for about 30 seconds till I realized that it was still stuck to the face plate. The mic is the same as the ones found other Kyocera models. You can probably find one on ebay. In fact you could probably use a mic out of any brand cell phone as long as the contacts touch and it fits in you r faceplate.
    If you buy a phone off of ebay for the part, it is cheaper to buy one that is stilllocked. It won't work with your service, but it will work for parts. Any of the kx models will work.

    Thanks, mr.java!

    I have my eye on a KX433, as I hoped the guts were simular enough. I also have an old Qualcomm 2700 here. They are the same as kyocera right? Maybe it will be compatible.

    My gratitude to you, sir!

    The 433 should work,I don't know about the Qualcomm. You could take it apart and see. Just make sure not to lose the mic or the earpeice. Also be careful not to lose the contact where the charger plugs in. If it is like the KX414 than those three parts will tend to fall out on there own. I gave a brief explanation on how to take apart the KX414 at http://cellphoneforums.net/t145832.html

    VERY nice tutorial. Wish I read it before I trashed my mic. Auuuugh.

    Hope you save someone else the headache

    I lost a few auctions so far trying to get a parts phone. I might just break down and buy another. Maybe I can sell mine for parts

    Thanks again!

    Aparently people have had a problem with the battery contacts falling out when taking the KX414 apart. So be careful, ther are four parts that can fall out easily. The earpeice, the mic, the charger contact, and the battery contact. So be careful watch for these parts. And also avoid static electricity, these phones are sensative. The best would be to use a grounded wrist strap.

    Oh yeah, do you know the pinout for the data cable? I would like to make some for cheaper than $40. They plug right into the headphone jack, so it can't be that hard to make. Hopefuly someone can figure it out and post it.

    Kyocera KE433 Microphone part

    I have the same problem -- replaced the case of my KE433, and now the internal mic doesn't work. I thought I'd worked carefully, but I didn't notice a part that goes between the microphone (in its green rubber circular casing) and the circuit board. Can anyone describe for me what this part looks like so I'll know it if I see it? Or is there a way to improvise the appropriate contact between the mic and the board?

    Many thanks,

    bzl

    I have the same problem with the daughter's phone. Anyone know how to make contact between the microphone and the circuit board?

    Kyocera KE433 (Rave K7) Problem Solved!

    I recently ran into a problem with my Kyocera KE433 (Virgin Mobile's Rave K7). I ordered a replacement "faceplate" (actually a new front case and back battery cover) on eBay, and when I moved the guts of the phone to the new case, the internal microphone stopped working. I could plug in an external headset/mic and that would work fine, but the built-in microphone was dead, for no apparent reason.

    Another member reported the same problem, with no solution, and I found a couple of other folks in other discussion groups on the web reporting the same thing.

    I've been doing some research, and have identified two possible causes of the problem, as well as the accompanying solutions.

    There were suggestions that there might be a piece that should go between the microphone and the circuit board, and that this piece went missing when I was replacing the case.

    It turns out that there is no piece that goes between the microphone and the circuit board. However, there is a bit of clear plastic -- an *elastometer* -- that should be over the center of the microphone, on the side that faces the circuit board. This is the side with rings, rather than the black side. When the microphone and the circuit board are properly in place, and the case is screwed together as tightly as possible, the elastometer makes contact with the circuit board and causes the microphone to work.

    So: look at the microphone. Is there a clear plastic circle on the side that faces the circuit board, or did the elastometer fall off when you switched cases? If the elastometer is missing, you'll need a new microphone. Other than finding a similar mic in another cell phone, the only source I've located in the last 24 hours is Universal Cellular, in Orlando, FL -- www.pcsrepair.com -- (407) 438-7766. They offered to sell me the mic for $20, plus $5 shipping. There may be cell phone repair places in your area, and if so they may be able to get the part. The technician I spoke with at Universal Cellular, though, gave me the information I needed to figure things out, and so I'm happy to give them a shout-out.

    On the other hand, if the elastometer's there, then it's quite possible that your mic's fine, and the problem may well be that the replacement case either isn't screwed together tightly enough -- or that it's poorly enough made that even if it's as tight as can be, the elastometer's not making contact with the circuit board. To see if this is the real problem, try reassembling the phone in its original case, and screw it together as tightly as possible. Make sure, of course, that the black side of the the microphone faces the front of the case, while the elastometer side (with the circles) faces the circuit board. When it's reassembled, see if the microphone is working. If it is, you can try reassambling the phone in the new case, and screwing *it* together as tightly as it can possibly go. Then you'll know if the problem is the new case itself, or if it just wasn't screwed together tightly enough.

    Turned out it was a case problem for me. The phone's back in its original case and works again. Maybe I'll get a new faceplate. Just the faceplate this time, but not a whole case....

    Hope this is helpful!

    VERY helpful. That identifies the problem with the new case. Thanks.

    Problem solved

    Glad to be of service!

    Incidentally, where'd you get your case from? Both the one I had problems with and the one another user on another board had problems with were eBay purchases, and it turns out they were from the same seller -- Sunchamp Corp., whose eBay ID is wholeaccessories. They did a fine job of shipping the cases promptly; but wonder if maybe they got a batch of KE433 cases that just aren't quite up to spec.

    Kyocera speaker

    The Kyocera Rave mic in the lower part of the phone will not work if you screw the shell down too hard. Ther is NOTHING between the green speaker and the board. I thought the same. Just snug up the screws and experiment with the phone. I had the same problem. My phone works again now.....:-))

    Same eBay Seller

    Yes, this was my seller too.
    Facinating.
    Maybe someone should warn the seller?
