No TX on my tti 881

Today I noticed my cb radio a TTi 881 wouldn't transmit.
The meter didn't go up on the LCD screen. I put a swr meter on and no movement on the needle. It receives ok.
I was messing around with things and took off the mic while it was still on. Would that have damaged it?
Are things like this common with radios and would it be repairable?
Any ideas would be greatly appreciated
Thanks

Do you have a multimeter Ohm meter ,if so put it across pin 3 and 5 of the mic plug and key the mic ,It should show continuity when keyed , If nothing then there is a wire break in the plug .

Thanks for the advise. I don't have a ohm meter. I'll get one on eBay. What setting would I have to put it on?
I'll have a look and see if I can solder it.

I ordered an original mic from Thunderpole
I did try and get take the plug off the old one but after taking the screws out it wouldn't go over the the rubber part that the clamp bites onto. If I forced it I thought it would get damaged even more. I'm sure someone knows how to do it though.

I got a new mic from Thunderpole in the post yesterday, all working ok now. If I get the old one repaired then I've got a spare.

Well yesterday I posted another thread regarding low mods. It would seem my brand new tti mic doesn't work properly.
Is there anything could do to return it as faulty?
