Doug Posted May 1, 2018 Share Posted May 1, 2018 We have an NV-2020 that has been working trouble free then out of the blue it stopped taking money. During power up self-test it displays the following Coin mech - NO Bill mech - NO eport mech - NO I've never worked on vendor machines but because I have a back ground in electronics I was asked to take a look. I could not find any schematics online. I have reseated all the connectors to see if there was no change to the self - test and no improvement was made. Any help is really appreciated Link to comment Share on other sites More sharing options...
