Hi all, i have an original Zaxxon PCB , works fine,
there's one only imperfection,
when the game start , sound nedd 4-5 seconds to start,
the sound is 100% working and also synchronized , but starts 5 seconds
later than video.... it appens only when the board is turned on the first time..
is it normal?


regards


Francesco
 
not how the board should work but not necessarily surprising. It's pretty well documented that there are a group of something like 12 capacitors on a zaxxon board that with time eventually go bad as all capacitors do and need to be replaced. These caps are specifically tied to the sound on a zaxxon board. My guess is one or more of the caps on your board is on its way out and should probably be replaced. My guess is your problem will get worse in time and eventually you will have no sound until these caps are replaced.
