i90c earpiece problem.

I put a new lcd in my i90c and now the earpeice doesnt work. is the only possibility a faulty lcd? or is there something else i can try. i have tried 2 diff. earpeice speakers.

Are you sure you didn't damage the ribbon cable going into the flip upon reassemly??? Once that's broken, it's pretty much the circular file for the phone. Don't think Moto offers replacements for that part because you void the warranty by doing the work yourself.
