    The Screen turns for a few seconds, only to darken from outside to center. Then no picture only sound!

    Replaced the Main Board and did not fix the problem! TV still turns on starts with a dark center. Seconds later the screen fades black from outside to the inside. I have heard this called the screen of death. Before I purchase another part (Power Board) anyone had this problem can tell me how to fix it?

Do you have backlight? If you do, you have a bad main logic board. Very common with vizio and are hard to find. They are usually out of stock everywhere.

    Back light has been tested with LED flashlight. I can see the screen and displayed image for a few moments until it fades from outside to center before completely going black.

Horizontal line at top of screen in any hd format with componet or hdmi. model is sv470m. the tv isn't even a week old.

Get into the TV menu and locate the H (Horizontal) and V (Vertical) picture options. . .increase the V until line at the top is gone.

Made popping sound then picture went black

I have the Vizio JV50P (Plasma) after 2 months it's started to make a loud pop sound then no picture. Vizio sent a third part repair man to replace the power board, main board, left and right sustainer boards and no less then 24 hours later... I had the same issue. I was just on the phone this evening with "Vizio level 3 support" and they out right lied to me. They told me they never heard of this issue before and yet it all over the internet. Shame on me for not searching the internet more thoroughly for known issues with Vizio products. If I had I would have easily found the term that seems to have associated itself with the Vizio’s line of flat panel TV’s ‘The Pop Of Death”

I am current climbing the Vizio Org Chart to get my money back. I have spoken from level 1 thru level 3 tech support. Who were willing to replace the defective unit with a refurbished unit!!! NO WAY! Then I spoke with a customer service rep and then his supervisor. “No Help!!!” They read from a script and showed no compassion for my issue. They too wanted to send me a refurbished set that is only covered by the balance of my warranty! A set that has the same issue that they can not even prevent from occurring and sets made as recent as 9/07 (manufactures date), new sets! I just left a voice mail message with the Customer Service Manager of Vizio corporate (aka V, inc.) and will await his call back tomorrow. I then searched the internet and found the term that seems to be growing in association to Vizio… ‘The Pop Of Death’ I can not wait to hit him with that term tomorrow! If I do not hear back from him, I will contact his superior. It’s very easy to find that information on the BBB. As far as I am concern Vizio is not only a poor product but a deceptive company who so far does not stand by their product. I will follow up this post in a week or so.
