I've owned this Captain Fantastic machine for 15 years. Now, it just went dead. When turned on, the playfield lights flickerand then go out just for a split second and nothing happens...no lights, no nothing. I think, maybe it's a fuse since just before it went dead, I turned the machine on and off, a few times, very fast by accident. I found 3 fuses in the coin door that look OK, but there may be fuses behind the backglass or where???. In any case, I can't figure out how to remove the backglass..there is no key slot on either side. I removed the back door but I don't seem to be able to access the backglass. Any help would be appreciated. Thanks.
