I have a Macintosh Classic that a few months after recapping (and replacing diodes DP3 DP4, the optocoupler, and the TDA4605 chip) started exhibiting a wobbling in the lower bottom of the screen. The wobbling disappears gradually (line by line, from top to bottom) as the Mac warms up, taking from 30 to 60 seconds. Once the Mac is warmed up, it does not appear again, and the screen remains rock solid. The wobbling does not appear at every startup, only when the computer hasn't been used for a few hours (hence my idea that the issue is connected with the temperature of the components. The issue is also linked to this specific analog board: when swapping it with another one (also recapped), I cannot replicate the issue. Has anyone ever had this problem? Should I just ignore it, or is the analog board failing?
