help with tron (no sound)

[draginit]

welp, after 2 years i was finally able to pull all my machines out of storage..and one by one i am going thru and trying to get them working again.



ok, so my TRON fired right up and plays fine...but i have no sound. also the lights to the coin door no longer light up. its been so long since i been able to work on anything i have forgotten a lot..anyone know where to start looking for no sound issues on tron..
<----IS this the sound card?

what i done so far..checked fuses of courses..the sound board appears to be fine no corrosion or heat marks. i checked all the wiring to the speakers..what else can i check??

That is the amp card. Dunno what you're issue issue other than that.

Everything else plays clear ?

[draginit]

yea,,screen is clear,,controls play fine.

can the sound pot control by the coin door just go bad and cause this?.  i just noticed the counter on the coin door stopped working too.  so the coin door basically completly has failed minus the credit switches
