I'm new and have a machine that don't work

[jcgauthier]

I just got a pachislo machine .I got no led display,I got a little hum from the speaker and thats it.Inside the machine on the what looks like the main bord there is a bunch of led light.When i play with the buttons on the front the lights will light up depending what button is pressed.I did do a reset and nothing.I do see on the main bord with all the led lights there is two particular lights that have me1 and me2 printed by them.I never seen them light up.Does those lights stand for memory?Any help would be great thanks
