Keyboard on TP seems to be dead!

[alfredo-x]

so does anyone know of a guide, a walktrough or something that i can do to CHECK the keyboard on my TP?

i have the screwdrivers and everything, i fix laptops, and i've opened up phones before, but i would like a guide that specifically tells me what things to look for when i open my TP to see if the keyboard is working...

because the phone is in LIKE new condition, never been dropped or nothing, it's mint. so i dn't understand why the ****ty keyboard doesn't work anymore!

and i've tried flashing it to many different roms and the same ****.
also i have 2 other TP's, and those work fine on any ROM...
