Stargate flippers

[scottnds]

Hi.
I am having trouble with my Stargate. After a long time I had a game on my Stargate and the skill shot in the  Sarcofagus was not registering. I cleaned the contacts on the roll over switch in the sarcofagus and it worked 50% but then the 2 bottom flippers now do not work.The top flipper works and the 2 bottom flippers move slightly about 1-2 mm.
Can anyone point me in the right direction to fix this.
Thanks
Scott

Did you accidentally disturb the wiring / switch on the upper Right Flipper ?
Do the lower flippers move freely by hand ?

Thanks.
I have just had a play with it and the flippers were the same so I moved them into the hold position a couple of times with the flipper buttons pressed and now they are working. And the sarcofagus is working again also.Is there anything I should be checking for? I have my pins in the shed covered so would this cold weather affect them in some way? I will check wiring on top flipper. Thanks for your help.
