Folks, i bought one of these sets last week and am impressed with it so far. however i have a problem with it at the moment in that the VGA input from my PC doesn't work. When i try to switch it to PC mode, i can see my desktop on the screen in perfect clarity, however for some reason the LCD TV does not detect the signal and it flashes a message on the screen that says "ATTENTION: NO VIDEO INPUT" and after 5 seconds it switches the set into standby. I have tried three different PCs and it does the same thing on each one. Is there any way to reset the electronics in the lcd tv so that it doesn't give this warning message, or will i need to bring the unit back? Also, someone else on this forum mentioned that you can add a DVI input on AV3 but didn't explain how to do this, if anyone knows anything about this it would help too as i could use a DVI input to the LCD instead of a VGA cable. Cheers peeps!
