Wii having problems with 480p output?

via engadget

A thread over at the Nintendo of America forums has highlighted a potential problem with the Nintendo Wii's output of 480p signals using component cables. Over a dozen members have reported blank and flickering screens on a range of televisions from 30" Toshiba CRTs right up to 65" Sony XBR LCD TVs. The type of cable isn't limited to third party solutions from the likes of Mad Catz, Psyclone, and Joytech either: several reports indicate that the standard Nintendo component cable also exhibits the problem (no word on whether DIY will save you). Strangely, the problem -- which Tharealfofo states is "like nothing is connected" -- occurs in similar sections of certain games and applications: several forum members have mentioned that the screen goes blank during specific sections of Zelda, the Wii Channel, and in the Opera browser. Switching to 480i output in nearly all cases fixes the problem. The broad mix of configurations that are affected suggests that the problem is the Wii itself, so hopefully Nintendo will issue some form of update in the not too distant future. In the meantime, feel free to sound off in the comments about how being forced to view your games with interlacing is a breach of your fundamental human rights.

The problem is there,
Some games went black on me, but there is another problem as well.

I have a european console with a sharp aquos hdtv connected to it, almost all really old virtual console games cause the tv go blank, sometimes it switches itself into black mode for a few seconds during normal games.
I assume this is a cross interference between the signal and how the tv tries to interpolate it. I am not the only one with this problem although it is not very widespread. It could easily be resolved probably by scalers in the virtual console on nintendos side.

Newer games like mario 64 work fine. I switched to rgb mode, which also has a problem it basically leaves a locking signal on if you have wlan set to constantly on. This is a known problem and I have read several times about it.
To me it seems like Nintendo has not tested the video outputs well enough (at least not rgb and component)
