C compliant EEPROM, stores EDID data for HDMI.
Write-protect can be released from service menu.
IC401
MCF52258AG80
Microcontroller for LAN control.
Once this microcontroller is replaced, the firmware/ MAC address is cleared.
Since the MAC address is not allowed to be written on the occasion of ser-
vice, it is not established as a service part.
