My tv was not in used for two weeks when i put it on hearins sound no vedio

You could check your video card in the settings sit will tell you if your vedio card is working what is are you using

I'mnot sure what you mean,"i am hearin anouice"? I don't know your OS, so this solution is a general idea. But if you open Control Panel, Sounds, Open sounds tab, change. respond to post for further assistance. If you are hearing a noise, what kind of noise and comming from where?

check the vedio input or tv cable for the wii take them out and put them back in again do this until it works

try use vedio input for work....or use vcr ant in vcr vedio output to tv...
no need replaced tv

First, try updating your audio drivers. Next update directx to the most recent version. If you still have no audio in game try checking out the sound settings in the game itself.
Let me know how that goes, and if it doesn't work let me know what type of sound card you have, which game you're having the problem with, and the operating system that you run. (Windows XP, Vista, Linux etc.)

that is possible
the home theater has so many in puts on your dvd and out puts.
there is a way
1 you can buy a vedio/audio converted to rf signals, this will mean both signals entering tv using rf.
2 get your vedio out from dvd and audio out, feed that to a converter, vedio in and audio in okey

the difference between tv and av, is that av has no showers on the screen. if you change to av you will notice a blue screen, connect your yellow on vedio output and white/ red on audio out of tv
note- before connecting to a vedio touch a tip of your vedio cable some lines will show on your screen, if touch your audio tip harming noise will sound on your tv. if this two happens then you know that your cables are okey. hold your channel button on your tv, channel will start runing after all rf channels finish, tv will go to av.

Right, S-Video is higher quality video only, sound still goes out through 'red'/'white' RCA phono plugs near the other (lower quality) 'yellow' video out

Same happened to my ps3 one week from new , took it back the the shop and got a refund.

have you check with other input like a vcr?...good luck
