In addition to cable connectors, there is one other vulnerability that we often overlook. I had an intermittent problem with my organ (KeyB) that was driving me crazy. Description of the problem is unimportant but it was obviously electronic. I described the problem over on the Keyboard Corners forum and someone suggested that I RESEAT the 4 main circuit boards (one for each set of drawbars). Despite a lot of skepticism on my part, I tried it. Three of the four could be seated more firmly into the motherboard. After reseating and closing up, I turned it on and Voila!, no more problems. That was two years ago and I have not had even a hint of a problem since (and I play it daily - extensively). Yeah, yeah, I know....the screws, but it might be worth a try.
