i think my key board is officially dead

[jamaican_sole]

i have a sprint tp which ive flashed over to metro, and been using for with no problems for sometime now. recently ive been having problems with laggy text, sticking keys ,and now the keyboard simply doesn't work. i came across a thread that instructed me to open it up and reseat a couple of ribbon cables. while that fixed for a little while, it ended up going out again. i reseated the cables again, but this time it didn't work. backed up my data and tried a hard reset and still no key board.
my question is, are there any online suppliers from which i can purchase a replacement keyboard from?
