This may have been addressed before, but I can't find it. I have a Bally Paragon and I cannot figure out the trick to pulling the light bulbs out of the sockets in the pop bumpers. All 4 of the pops are giving me the same problem, the bulb is very hard to turn, once it does come out and I install a new bulb it is very loose in the socket and only lights intermittently. I think the bulb being so hard to turn is causing something to bend out of place so when I install the new bulb it doesn't get good contact, but I'm not sure. I guess I could just put a dab of solder on there and fix it, but it doesn't seem like this should be so complicated. What am I missing here?
