having trouble with my MTS2000 audio

[fflores561]

So I've had my Mts2000 for 5 months and it was working fine in till 2-3 weeks ago..The Audio started to cut off in the middle of radio traffic and now it seems like it got worse!...i have to keep pressure on the speaker in order to listen if not i will not hear nothing at all not even the button noises...So obviously it has to do with the speaker since it seems the problem is there..I currently have 2 rubberbands around it with a couple of small folded papers holding it down so i can listen(some times the radio traffic comes in fuzzy but u can tell its the speaker).When i connect the shoulder mic it works perfect since it has its own speaker...What do you think it may be? a lose screw or something?any thought?

if you open the case you will see a flex strip going from the front housing to the main board. the connector on the board has a clip that sides out a little bit. slide the clip and fully reseat the strip. also double check the little double jumper between the RF and the main board, this usually kicks up.

to open the housing you unscrew the antenna, pop both channel and volume knobs off, remove the battery and you will see 2 slots at the bottom. insert a flat head screwdriver and pop the housing off the tabs at each side. the slide it forward enough to clear the volume/channel switchs and lay it open. do this carefully, if you snatch on it you can ruin the flex strip.

i have seen it a couple times where the solder at teh speaker cracks. if this is the case use just enough heat to melt solder, about 350, and only touch it for a second or you melt the flex.

Try what David said, this way you cover all your basis, but in my opinion, sounds like the voice coil in the speaker going bad. I would replace the speaker.

my ptt mic will not work

my ptt mic will not key up or i cant hear anyhing I tried to take it apart but it have to take the back off

 

[rescue674aa]

and its hard to take off

 

[davidgcet]

i told you how to take it apart.

with both speaker and PTT not working i am leaning towards either the flex strip is bad or kicked loose.

Mic

My mic ptt and mic don't work but the ptt on the radio works

 

[davidgcet]

if you popped it partially out of the case the side connector is no longer contacting the internal contacts for the accy plug.

Mic problems

I don't what to look for I'm so lost

 

[davidgcet]

my suggestion would be to take it to someone who does know then, honestly if you cannot tell if a flex strip is kicked you do not know enough about radios to be fooling around inside it without hands on help. this is not a dig at you, everyone is at that level at one time or another.

if you screw up the flex, expect to replace the front housing. if you screw up the connector on the board, expect to replace the radio as many places won't or can't fix it.

Maybe he is talking about the speaker mic? Some of the speaker mics had screws under the clips.

OK, it does sound like rescue674aa (not the OP) is talking about problems with a speaker mic. The OEM Jedi mics aren't easily serviceable because they're hermetically sealed. If the speaker mic's your problem, it's easiest just to get a new one.

 

[davidgcet]

yep, just realized we had a thread hijack. the problem with the speaker mic could be the cord or the mic head. neither are repairable, you buy whichever part you need. double check the pins on the radio end, the common problem is folks do not use the lock down screw and the pins break from the plug moving. last time i bought some from M they are almost 20.00 a PIN, much cheaper to just get a new cord.

 

[rescue674aa]

My speakermic work on my jt1000 just not the mts2000 so I know it's the radio.

Just Echoing what has already been said!

My suggestion is just do like the guys suggested and take it to a certified /\/\otorola radio repair shop. I have taken a few of these apart myself to refurbish them and you really have to be careful. A slight tear on the flex and you could be looking at a costly repair bill. If you don't feel comfortable or just don't know enough about this particular radio, let a certified tech handle it. It's the best way to go. Just a suggestion
