Will Sprint fix/replace my Touch Pro?

[Growf911]

I bought an original sprint touch pro from a friend about a year ago. In that time, I modified it to run on the VZW network under Page Plus. I have recently had major problems with the screen and keyboard.
First the screen began to distort colors. This was the fault of a ribbon cable. I replaced the entire screen/keyboard assembly and the problem was solved.

Now my keyboard has stopped working. I have checked the connections repeatedly, but on my most recent attempt I found that the phone is now stuck in landscape mode. The keyboard still does not work.

I have hard reset and changed roms but that is of no help. It is a hardware problem.

Is there any chance at all that Sprint would give me a replacement?

I'm tight on cash atm and I really can't stand to give up on this phone.

Thanks guys.
