Steven :

Hi my name isXXXXX may I help you?

Customer:

Hi Steven. I have a vizio tv that keeps shutting down and the only way to get it to start up again is to unplug it

Steven :

Ok, first off do you have the model number of the Tv ?

Customer:

it is an M420SV?

Customer:

I'm not positive where to find the number

Steven :

That looks like it might be right let me check

Steven :

Ok this like a new Tv, how old is it ?

Customer:

2-3 months old

Steven :

oh wow, still under warranty so see if we can determine if the problem is a defect in the Tv or something else.

Customer:

sounds good, how do we do that

Steven :

whe you say blacks out, does it shut completely off, no sound no picture any leds flash ?

Customer:

no sound no picture no flash

Customer:

it has "vizio" under the screen that lights up white when on and yellow when off but the light just goes out on the name as well

Steven :

when it comes on there must be a LED indicator telling you it is on, does the light stay on ?

Steven :

Ok sorry, you answered as I was asking

Customer:

not a problem. the blackout also occurs when a commercial starts in a tv show, or a cinematic fram takes place in a video game

Steven :

Ok but when it happends the vizio light goes back to yellow like the unit is in stanby again

Customer:

sort of, it has a little backlight but not as bright as it would be were I to turn it off on purpose

Customer:

the tv still hums like it's thinking but sound and video shut down

Steven :

does it do this no matter what source you are using, Cable DVD player ect ?

Customer:

yes, it does this whether I'm playing a video game or watching a bluray on my playstation or watching tv

Steven :

Ok I have enough information to know that this unit has a serious problem on the main board, it is not something you will be able to fix with a reset procedure or anything like that, it is going to need service and the fact that it is still under warranty I would definately recommend contacting Vizio to find the closest service center to you. would you like a link to the vizio website ?

Customer:

yes please

Steven :

I wish that there was more I could do but should definately not pay for parts or service on a unit that is so new. http://www.vizio.com/index.php

Customer:

Not a problem Steven. I appreciate what you've been able to tell me.

Steven :

Your very welcome
