Title: CPU Crackling and Popping Issue Post by: jimbo68 on March 19, 2016, 10:55:17 am Howdy. Glad to join you all. I have just gotten into picking up mostly 70s and 80s arcade games. One such is a Tandy 51 game upright arcade cabinet style game that is a project. I have plugged it in a couple of times and there were some issues with interfacing in the game selection screen. At times I could not select the game I wanted to play. However, today, I plugged it in and heard a crackling sound and then nothing came on. I unplugged, disengaged the CPU harness, turned it back on and no crackling sound. I reengaged the harness, re-started the game and got the crackling and popping sound and no game again.
The game is out in the carport right now while I paint the cabinet. It is in the 60s and drizzly, so it is humid. Could this be the issue? Would love to get some insight, as I really don't want to ruin this project game. I certainly will be happy to answer questions or even try to post a video if needed. Thanks, Jim |
