Any ideas on what cause that? Is my board dead? Please let me know.

Thanks

 
Its trying to boot. Check the z80, eproms in row 6, sync bus card, 2114 ram. It could be any of these among other things but this is where you should start. Check 5v across cap C3 and make sure its a steady 4.9-5.1v

Impresive. Thanks. I'll try that soon.
