Watching tv last night and in middle of movie the tv went zit and thats it never had a problem always had great reception and great picture. it's a 50c10 hdtv

Even u have no satellite or u have a box that just ruined ur tv trust me that happened to a lot of my tvs

There could be a few things that would cause this. I would suspect that you have a problem with either the power supply board or the main board. Based on my experience, the main boards go before the power supplies. What is the model #

Sir try to check the cables connection at the back of your tv. and if you are using a digital receiver, try to use a dvd to check if there is a sound. If there is a sound the problem is the digital receiver, feel free to send feed back good day and best regards.

Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

have you tryed adjusting the picture in the menu section! this may help!! or on back of tv is adjusters those may help as well.

ive only seen that twice, and it was a pannel failure (shorted) causing loss of power to the pannel.

Good Day;
You may have a lamp going bad,when was the last time you replaced it? Or the DMD or light engine, try lamp first. Good Luck, big IRISH.

The same thing happened to me Twice!. First time it was under warranty. Now it it out and Vizio has not interest in helping me. The first time the repair man changed the motherboard, which worked for about a year. Looks like I will be buying a new TV soon, but certainly NOT a Vizio, they are junk
Anyone out there know how much a motherboard costs?
