You don't say what you are trying to input but take note that your model does not have a digital tuner on the DTV input. If you use a digital OTA antenna, the signal must first go through a digital converter or tuner before it goes into the DTV input. The DTV/ANT input is only cable ready. There is no digital tuner in the TV to activate the DTV menu.

You have a bad panel. The sad thing is that Vizio knows that.

What is the problem with teh screen?

Noting I can think of other than not wathcing a channel without commercials.Commercials' volume is purposefully pumped up, that's a well known fact, The TV doesn't make a difference between what's commercial and what not though - it just plays whatever stream level is being supplied.Well, the amplification may not be and probably isn't linear, but regardless, the point is there's nothing you can do on the TV's end.Another TV may be a bit less obtrusive, but commercials will always be louder and if whatever you watch is a bit more quiet than usual and you put the volume up to hear it then yes, ads will sure blow you when they come.www.coppelltvrepair.com

It can be the T-CON board, main board, unstable power supply, worst case will be the LCD panel, posting the pictures will help.

It sounds like the power supply went out. Fuses do not blow for no reason in an LCD set. I would have it looked at by a professional service center.

If u have the garantie u can get it fix by the store u bought it and if u dont have a garantie u can always go on google maps search screeen replacements at ur city and choose the near one for u.

This problems,the Tuner board is also dead,sometimes both power board and the Tuner board are dead.Replaced the Tuner board,will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

If you are absolutely sure that everything is hooked up correctly and the tv is on the correct input, then you will need to replace the main board. You can find them new or used on ebay here...

You may want to try a different hdmi cable first to make sure, but it sounds like the board may be bad. Good luck!
