Recently I modded my Creativision to add composite video and audio. While I thought I had succeeded, after a while I noticed glitching and visual artefacts. By making my mod easily reversible, I was able to unsolder the added leads, reconnect the disconnected power lead to the RF Modulator, and it worked fine.
I will probably revisit the mod. I suspect I’ll need to completely desolder the RF Modulator and just tap directly in to the 3 connection points it was using. (I can leave the ground connected)
