Nava don´t works, help. Microcontroller problem?

Discuss Nava construction and related issues
  • I just tried to initialize the eeprom, it does the init but any change. I loaded again the firmware via midiox, it does the transmission, it load into the nava but no way.
    Sequencer not running,no characters on the display only red boxes, any sound... I checked the voltajes again and I am getting 13V instead 15V, before the io pcb it´s 15V, after the I/O I have 13, its normal? maby regulators not workin properly?. Maybe not enought power for running the nava properly?

    Thx in advance, I am an expertisser DIYer but I am not electronic, so maybe I missed something important but an electronic friend of me is almost sure than the atmega is dead.
