Have you run the rom tests from service mode? You may have some bad chips, which is not the end of the world. They're pretty easy to replace these days.

Hi, thanks for your answer, yes i test it on sound test and some sound not work, but you are sure that exist roms test?
 
I think they call it Memory Test but it also tests ROMs.
With any luck, it will be able to indicate which one has a bad checksum.
Then you can contact someone like Ken's Hobby Roms to get a new one burned (or multiple).
