full graphic controller 12864 help

i touched the control knob on my controller and received a static shock. now the lcd screen only displays white blocks where the characters should be. any chance i can fix this?
if not anyone know if just soldering on a new lcd screen would fix it? they're about half the price of a new controller. sd card still works too

my guess is i corrupted the lcd firmware. anyone know if these can be reflashed?

Does the LCD have its own firmware? Perhaps just try reflashing the printers firmware.

No. The LCD is controlled by the ST7565R driver IC, which is probably shot.
