I posted in the wii channel a few days ago but I wanted to make a post here before I buy a new connector just to be safe.
I've tried both Wii2HDMI and Component to HDMI converters and neither are working. While the Wii is on, my tv doesn't receive a signal at all, but after it idles for a few minutes (or i just tap the power button to make it idle and go yellow) it'll show the home screen very dimly (pictured). I don't believe it's a capacitor issue as I've left it on for about 15 minutes with no sign of it increasing in brightness and when I touch the controller, turn on the sensor bar, or press the reset/eject buttons on the console it'll snap back to no signal to the tv. I've also tried this on a few screens but the only way the video output is working is when I use my original component cables, but we’re about to get rid of the only tv in the house that even has those ports, hence why I wanted to use converters.
