      I did some testing. If I put a jumper wire between the CS pad and multi AV out pin 3, the scaler picks up the CSYNC and I get picture and sound as intended. Also, if I put a jumper wire between the CS pad and the left side pad of J3, the scaler picks up the CSYNC. So does this mean the problem is that the CS pad isn’t connected to the right side pad of J3 internally? How would I test why this is the case? Or is the problem something else entirely? The picture looks great—and to my eyes exactly the same—whether I connect CS directly to pin 3 or the left side pad of J3. The weird thing is that J2 is now open, which should result in an image that’s too dark because I’m using the 470 Ohm CSYNC SCART. So I’m also bypassing J2’s resistor when I connect CS to J3?
