I was soo excited to play my console on HD, oh well the adapter doesn't work for my N64, shows a blue screen no matter what, tried my SNES, same deal, blue screen, says you don't need power, tried both alternatives, used a 180$ monster HDMI I have for my home audio/video for my projector / theatre system, tried different cables, so back to the original RCA plugin until I find one that works, my consoles are old, but I'm the original owner with receipts and they work so long as I use cables included RCA, I think I'll return this and get an RCA to HD converter instead, was trying to finally throw out this old tube tv, but I'll hang onto it for now so my kids can continue to enjoy my old games.
