I purchased Black Knight 1980 Pinball Machine from someone that let me know that it works when it wants to.
That should have been my first warning but purchased it anyway. I did some research and after adjusting the
switches and adding 3 balls to game I was able to play a game. After playing a few games the machine would
start making weird noises and lock up.
I took all boards CPU/Driver and Power Boards to have them professionally serviced and hoped that would address all the issues.
After installing the serviced boards I am able to play 2 or 3 games and then credit button no longer works. When the machine is working
one of the digits in the player 1 score likes to act up but pushing one of the top connector on CPU board fixes issue for a while.
I did re-pin connectors on top of CPU board but still getting same issue. I plan on asking the tech to re-solder top connectors on
CPU board that feed the score displays to ensure they are making a solid connection.
After playing `several games I can add a credit but can't start a game by hitting the credit button.
I turn off machine for 15 minutes and then I can play a game again.
Issue also occurs if I just turn on machine and let it sit for 30 minutes or so, everything looks fine, I can add a credit but credit button does not start
a game after machine has been on for a while. Seems like issue is a function of machine being on for a while. I am bringing boards back to be serviced
again but am clueless on this one. Code on CPU board is 0 with coin door closed. Displays, Lights, Sounds, Switches and Solenoids test out fine using the test
mode in the coin box.
Have you ever run into an issue like this before??? Hoping to have some ideas of possible causes before taking boards back to be serviced for a 2nd time.
I see lots of people solving issues by replacing the connectors between the CPU and Driver boards. Tech claimed that was not necessary when he serviced the
boards the first time.
