YAMASA part TNA024A light and sound board pictures please

[michellealin]

Hi All,

I am at the end of my wits on my first pachislo.
Everything is working well - except for sound (no warning/error is given by the machine).

I did a reset but doesn't fix the issue.
Traced the wires to main speaker and it is connected.

I received a suggestion to look into the possibility of busted light & sound board. I'm not sure how to check but just experimenting for now.
I detached the yellow and blue cable connecting CN5 (bottom left of the main LED board) from CN3 (top left above volume toggle of sound board part number TNA024A). see pictures attached.

The current operation of machine did not change so this connection (disconnection) doesn't have any effect on machine current state.
Since is right above volume - I'm thinking maybe it is the light/sound board TNA024A?!
I do have to reiterate that all lights are working well. Is that possible that light and sound board is busted only for the sound piece and light piece is working...

I am unsure how else to test this part but I noticed that the only section lit up on the light and sound board TNA024A is the LED2 at the top right corner and the section between black and blue cylinders a little off center to the right.

Requesting help - please post a picture of this part of your Yasama that shows sections that are lit.
Any other suggestion on how to test the light/sound board is greatly appreciated.

Well I know pretty much nothing regards electronics. But I would locate, each speaker and trace each speaker wire from each speaker back to the board. Checking both speaker connections on each speaker. then removing and reseating any cables/sockets on route.
