Hi. I have a Williams Flash with a problem. I had my power cord short out when my daughter started up the machine the other day and since then (it has been properly fixed) the bottom left segment on all the digits on player 3 and 4 displays intermittently dissapears. I have checked all the resistors on the master display and even swapped out the display for a working one and the same issues were there on the player 3 and 4. Is anyone able to tell me where to go next with my troubleshooting?
