VGA to SCART cable bad signal?
« on: October 08, 2024, 11:01:29 pm »
So I have a CRT TV on which the RGB inputs got borked recently (everything is blue), and I don't know how. So I've been trying to figure out how to bypass them and get a 240p signal through to the S-Video input instead.

Originally, I was using this adapter for VGA-out on my Radeon:

Using CRTEmudriver, it worked great until the TV got messed up.

So I decided to get a VGA to SCART adapter and then an SCART to S-Video converter that was designed for the MiSTer. Here is the cable:

Before even trying the subsequent adapters, I decided to test the cable out with the original adapter, since it has SCART in; but it outputs an unstable signal to the TV. Tried again with just VGA, and the signal is stable again (but still blue obviously).

So what's going wrong here? Why isn't the VGA signal going through the cable and into the adapter the same way it would if it were just going through a VGA cable into the adapter?
