I have this exact clone and it seems I have the same symptoms:
- No sync (blank screen)
- No beep on startup
- No disk spin
- Power supply seems ok
Sounds like I need to replace the caps.
The rom package is broken, the main ROM is full of FD, you may read the broken rom and not put the correct one from your friend Alessandro. Greetings from Brazil!

Thanks Alexandre, it was an oversight and i never noticed. Added a new archive with only the ROM-1.
