I own a 555sbc bender, that was not used that much. I purchased the machine in 1992. I attemped to bend some conduit last week, only to find out the bender did not work. I contacted Greenlee's service dept. Only to be told that they do not support that bender any longer and don't have replacement parts needed to repair it. The bender has a power module and a control module. there seems to be a problem in the control module. Has any one had a simliar problem, if so how can it be fixed?
