would appreciate the help simply question no sound?

just wanted to know from the seasoned 1000 vets! basically bought a 1000 good good price couldn't pass it up knowing already that it didn't have any sound tried everything the guy was right just no sound so can some one just direct me to like what main board i can buy or just one part that has to do with sound that will just eliminate the possibility of ever being that so i can move on? just like the part i can buy and install/solder or whatever so i can just know its not that(sorry if i repeated my self) thanks a million

Good luck

Honestly there is NO way you can guess what board it is. If you are in NY I can take a look at it for you, other than that you might want to reach out to VST for repairs. You may end up paying more than its worth when all is said and done.
