Technobeam no working

Hello! I’m form Brazil, and I have a problem with high end systems “Technobeam”.
I’m electronic technician and have six fixtures technobeam: 3 run perfect, and 3 doesnt work.
These fixtures with no working have a problem in the microcontroller (I buyed without micro of other technician).
Ok, I buyed one new microcontroller (mc68331cpv16), and turn on the fixture.
But, he don’t work…run the display, but no reset and no show true caracters.
Can You help me? I tested the eprom (29f010) in other fixture running, and are every ok.
On the pcb have an HD1 connection. Is it an ICSP connection? Can I use this connection for upload the system?
Thanks, and good year for us.

    Hello! Thank you for your response.
    For me it would be difficult to send or buy anything from abroad, because I am from Brazil. I bought the gadgets because I'm a fan of the brand, and I really like technobeam!
    I'm an electronics technician and I'd love to fix them. Is there any other way to write this microcontroller?
    I have here the firmware file available on the site.
    An important question: are there actually files recorded on the microcontroller, or are they present only in flash memory?
    I looked at lightparts.com, and they did not own the pcb
