Denford Software & Machines

Hello I have I believe to be a 1997 Denford microrouter that I bought . It had a emergency stop button missing and the key . I replaced the Emergency stop button and just put the two wires together for the key . My 110 tester ( this has a 110v plug ) says there is power there . But when I push the power button on/off nothing happens . No light . And in the box where all the boards and controls are , my meter says there is power . But no led light . I checked the one fuse I could find . It seems ok . The router and the controls/ power are plugged in together . Are there any more fuses ? Where should I start checking ? Thanks in advance

I think these are fuse as well.

Thank you . Not sure if it’s the problem but they are fuses. I see how they come out. Definitely a problem ; hopefully it’s the one . This fuse is toast ( black ) . .
