I've been having major problems getting the AV mod on the Intellivision Wiki working on an Intellivision II. This is the second time I've built this mod, with the first time being on a Super Video Arcade without success. I have it built exactly according to the schematic, but when I first turned it on, the picture appeared nice and stable for a second. However, it began to fade out and now it doesn't display anything at all. If I turn it on again after a few minutes, a very faint picture will appear and then fade out to nothing again. I didn't disconnect the RF modulator in any way so I'm utterly confused here. The mod is here if anyone's curious: http://wiki.intellivision.us/index.p...o_Modification
