i had a good look at all the troubleshooting forums, but i couldnt see anyone else having this problem...
basically since the night i got my wii and installed it, the tv seems to switch to av on its own randomly every couple of hours. if you change it back to the channel you're watching, it just switches back again. it goes through a fit of doing this for about 10 minutes and then subsides.
it does this if im playing wii, watching tv, watching a dvd, or anything.
its very annoying as it completely disrupts what i'm doing.
i've taken the batteries out of the tv remote in case it was that, ive turned my wireless router off in case it was that, ive actually unplugged the wii and put the wiimotes in another room and it still happens, but my parents wont believe me that its just a problem with the tv.
i just want to sort it out, so if anyone else is having the same problem or knows what it could be, please tell me!
