I bought myself a Jaguar recently and immediately got tired of RF, so I made a set of temporary A/V cables that I can use before I buy a scart cable. However, it doesn't display a picture or output sound. The weird thing is that once the game starts up, my tv finds a signal and sometimes shows a picture for a second before losing signal again. Since it does display a signal, I know that the cable isn't an issue. I will try cleaning the contacts on the Jag's edge connector, but have any other people had a similar issue with this?
