My displays on player 1 and 2 are always "stuck" with 1111111 showing. I can see the score behind it. Hoping someone can point me to an easy fix. Machine power supply board has been replaced with a modern replacement. Please see pics.

Issue seems to be a bad connector. Wiggling the connectors seem to make it better/worse.

It did not follow the issue, and after moving them, all 4 came up correct. If I touch the connector, it will go back to showing 1111111 or fix itself (occasionally missing a segment or two). It is definitely the connectors that are an issue, and a touchy one at that.
