    It sounds like corrupt system software, bad HDD or RAM. Try reseating the RAM and Boot ROM and reinstall system software before replacing any parts.

    If it makes copies - check the LCD and/or the inverter board.

    I had to replace the whole control panel assy once. Dismantle the faulty one like yours, just to find out there is orange juice spill & sipped into the touchscreen...
