Hasbro FX Board with Removable Blade Diagram

[Alderscorn]

What kind of jerk necros a 6 year old post?! THIS GUY.

Any of you guys around know what might cause lights to work but not sound on this board? I've wired it with as few connections as possible for testing and its just like the diagrams. I've replaced the speaker with a crappy project one (just to test it) and there's not a peep.

I know the light has to be connected for the sounds but its not even doing the "fizzle".

I wasn't going to upgrade it, just try to repair it. But it might just end up being a paper weight.
