physical problem ... audio cuttoff with slider... - 8125, K-JAM, P4300, MDA Vario General

I dont know if anyone opend their wizard up.... mine is the tmobile mda..
the earpeice does not work when the slider is closed... or halfway...
the keyboard has to be slid completly open for any sound to be heard...
i know its a loose connection somewhere in the slide.... anyone know how to fix it?...
just started happening a few hours ago.

and now neither works... only works in speakerphone... wth is going on

It sounds as if your rigid flex cable is kicking it,
However your phone speaker could just be loose. It is affixed to the front plate and not the Rigid flex board.
I would try to troubleshoot with a dissassembly.
if the main ribbon cable is torn you should replace the rigid flex board. If your speaker is loose or broken You can look on XDA to see if someone is selling one.

ok.. i just read the service manual on how to dissassemble the wizard...
i just want to get a few things straight...
the rigid flex board is the board for the keyboard right?...
ribbon cable is that big thick silver ribbon right?...
if said cable is torn... i have to replace the entire rigid flex board? or can i just replace the ribbon cable instead?
if the speaker is loose... all i would have to do is tighten it... if it is broken .. all i have to do is replace it right?...
------
im sure the speaker isnt broken.... because it was working when the slider was slid open... and not working when it was closed.

Hi there bigjoe,
where did you find the service manual for the Wizard? I have audio problems myself (the mic and speaker just died, i can´t hear anything and the caller can´t hear anything, but the damn thing rings nonetheless!) and my warranty is up. So I would like to take a peek inside!

Ok, Here are the answers in order.
The rigid flex board is the board you see in the top portion of the wizard (where the screen and buttons are housed.)
The master ribbon cable is the big thick silver one yes.
I would replace the board it could just as well cause problems.(it's not too expensive)
If it is loose re-seat it in it's place. If broken replace it.

Have your first tried hard reset?
It sound as if your master cable is or rigid flex board going, but it could simply be your speaker and mic.

Hope this helps you.

Ribbon cable for the earpiece!? Possibly, but check the manuals on Link removed - no longer valid
I wrote a piece a while back for the TyTn (not the same phone I know, but similar). Have a read here:
http://forum.xda-developers.com/showpost.php?p=2001027&postcount=5
Now that front speaker directly contacts the m/board and the spring contacts can bend a little. Easy to fix if you are happy to dismantle.
Mike
thanks
the phone was closed when it fell so not sure on if it is the ribbion cable. also r u sure that the speaker is atached using the spring contacts, because i have the tools and the abiltity to take it apart just dont want to void my waranty if i still have on i have had it for more than 2 years.

I agree, if you have a warranty then use it.
If not, then I am puzzled about this earpiece ribbon cable. There are ribbon cables of course but not to my knowledge one for the earpiece. Can you post a link to the item on ebay?

i believe my phone is out of warranty but i might be able to reason with the people at the store. but if it is just reseating the contacts that is not hard fro me to do myself

i found this i think it is the cable listed on page 17. but as rthis is rather expensive i would rather be sure before i purchase

Agh I see what they're referring to now. The flex cable connecting the top daughter board. No - I do not believe it's the flex cable because that would likely mean the top buttons would not work either. Even if it is, the cable, it would just be a matter of re-seating it's push on connector.
In the picture the speaker is the darker object on the left side.
It looks an almost identical setup to the TyTn link I gave above.
Unfortunately it's a fairly major strip down, not just a case of popping off the back casing. The TyTn Service Manual would be helpful. Very occassionally the earpiece speaker is broken (rare - it's normally just the spring contacts), but there is a Motorola equivalent that will fit if you needed one. (The OEM speaker is not easy to source).

thank you both of my upper buttons works so im gusing it it not the borad. do you think that it is that much of a tear down because i have taken apart many apaches xv/ppc6700's and it was not that much work. also to reseat the contacts i just push on the speaker.

If you have some experience dismantling then it should be ok. The flex cable between the two halves of the phone may have some sticky tape holding the connector in place - that is a little bit fiddly, but not difficult.
To make the speaker make better contact with the board, you need to bend out the gold colored contacts just a little. (When the phone gets a knock / fall it can bend the spring contacts in and so it no longer makes contact with the board) The pics on here for the FRONT speaker show the contacts I'm speaking about. http://forum.xda-developers.com/show...27&postcount=5

ok so the speaker is just sitting on the board or is it held done by anything.

It is between the casing and the board. Normally the springy contacts make this a firm contact. After a knock the contacts get a little bent and it then rattles about and does not press on the board.
It is NOT soldered on, just pressed against the board (normally)

keyboard connector clip broken

Hi,
The keyboard stopped working on my device so I opened it up to find the tiny flat keyboard cable not properley seated on the mainboard. I tried putting it back but 1)its SOOOO tine and fidley, and 2) the tiny plastic saddle / clip bit that holds the cable down broke in half.
I suspect it may have been cracked already somehow and that why it came loose.
Anyway, anyone know where I can get one of these little clips? Any tips for putting them back together?
Thanks!
Anthony

[Q] Broke ribbon for keypad

So tonight I was replacing a broken digitizer for my HD2, it was anything but easy, but it wasn't as bad as I was expecting. Anyways, in the middle of reassembling, I hit the point where I need to reconnect the keypad. I was fighting with it for a good 10 minutes trying to get it connected. I grabbed a small flathead screwdriver to push the ribbon while my other hand guided the ribbon into the connector. In the process I broke the ribbon cable.
Of course, for the good of the phone, I've ordered up a new keypad. My question is, is there anything I can do in the interim? Can one say, line up the contacts on the ribbon and electrical tape it together? Or anything else?
Man just wait for the replacement keypad. Cause as thin and delicate as the ribbons are you will probably do more damage than good to the ribbon. I mean even if you got the ribbon aligned and tapped bake together. One you probably will not get a good connection between the two pieces of ribbon, and two the little copper strips are so thin you will probably cause micro cracks in them while you are fiddling with the two half's of the ribbon.

Damaged HD2 before even using :(

So i bought a used HD2 so i could get rid of my Aria and do a dual boot
The digitizer was bad so i bought that as well as a new screen, replacing it the main flex ribbon that connects to volume port broke which is unrepairable and the pcb where the flex connects to the socket lid broke half way when removing the tape so dang fragile.
But the ribbon still goes in and it still closes, so the main issue is the flex ribbon with the broken volume button.
So my tech is an idiot. But i really want to use the HD2. Is there somebody that has those parts and can fix it?
I already spent $65 on the digi and screen so i feel
Yes go onto ebay and look for hd2 side volume key pcb.
It's a lengthy repair but nothing too difficult if you like electronics.

found it, should have some fun now

Flex for volume button ripped, got soldering pin layout for volume buttons?

Hi all, my volume buttons stopped working after I ripped that part of the flex ribbon cable when I opened it up to replaced the touchscreen.
Anyone know where the pins for the volume buttons are located? I don't want to spend $ on a new flex ribbon, and I have all the soldering tools lying around...
Thanks.

You can identify your needed pins on main flexboard connector with a digital multimeter...
Regarding soldering, I wish you "Best luck"!

The volume buttons are parts of the main flex and cannot be resoldered. There are no pins and you cannot reattach torn flex. You need to replace the main flex, it is a large part and contains the side volume flex. But of course, if you believe you can locate the pins and solder - by all means, go for it!
