So here's a mystery that I had ever since I've had this TV.  As soon as I turn my TV on I can watch any channel as long as it's not HD.  If I try to switch to any HD channel (doesn't matter if its 720p, 1080i, or 1080p) my TV will not display the content.  It does display a message that says "NOT SUPPORT"    

Here's the issue...it's works FINE after about 10-15 minutes just like nothing was ever wrong!  

After about the 5 minute mark it will flash the audio and video for second to two second intervals and the longer I get to about the 10-15 minute mark the longer it stays on before flashing off again.  Seems like after 10-15 minutes it's like magic and works fine.  

I've tried multiple cable boxes, multiple cables, multiple resolutions, multiple inputs (both component and HDMI are affected)...same result every time.  

The exceptions are:  Netflix works as soon as it's turned on and games on my PS3 work as soon as it's turned on.  YouTube does not.  

ANY IDEAS??????

Yeah I've tried that....no better after cycling the power.   I timed it...the picture was watchable after 13 minutes tonight.  Audio starts coming in with video at about the 9 minute mark.  Until then TV says "NOT SUPPORT"

I was at the Vizio web site looking at a new tv for the grand kids, and ran across a bunch of little video on power cycling a vizio tv. its turn off then unplug it, then push the onboard power button for 10 to 25 second to reset the tv. I have always just unplugged in the past.
