Samsung RF23A9771SG Touch Screen not registering

I tried all the tricks to reset. Tried the secret menu. The screen will not register my touch. I have done a factory reset. Gone in the secret menu and did every item there. Unplugged the frig and the ON/OFF button on the door. Nothing seems to work.

If I plug a mouse in I can access it. Does this sound like the digitizer has gone bad? Is this repairable? or should I just find a whole new screen? if so, what is the part # for the RF23A9771SG?
