Korg Kronos screen not responsive

When it rains, it pours. I posted about a non-functional Akai S950 yesterday, today its my Kronos.

I tuned my Kronos on this morning and all keys/buttons/knobs/faders seem to work fine, the screen turns on, but is non-responsive to touch. I’ve cleaned it, tried a digitizer pen thing, nothing. I popped onto ebay and found either full replacement screens or just the digitizer panels. If the screen turns on and displays right, do I need to replace the whole screen, or just the digitzer panel? The panel is half the price of the screen and can be bought locally instead of ordering from over seas, so I’m hoping to hear it’s just the digitizer panel. Thanks in advance!
