we have an jv3 160s. the man would ran it and worked on it for the past 15 yrs. just died last week. it would not power up for him so he ordered a mother board and a slider board for it. he then died. i put the boards in and now when i turn it on it will power up. it them shows the error code 7 ***** and shuts back down. he also put new print head cables in before he passed away. i have checked and rechecked the cables and they look like they are installed properly and well seated. any help would be a blessing.
