SOURCE: vizio pixelation in hd nt all channels

Usually a TV that pixelates only on some channels is a problem with the signal levels coming into the TV or the cable box. If you are using a cable box then definatley the signal is the issue..

Pixelation


Hi,
The problem is more or less with the LCD screen itself. The manufatcurer covers dead or burnt pixels.I would suggest contact Vizio Support on the following number

I have a: Vizio SV420XVT1A.... The TV dont turn on!!... The logo light is off and have a sound like a beep beep and a red light blink a number 5.1 in the bottom of the TV


The main digital board to your TV should be troubleshooted. If it found faulty, there is no other way than replace it as card basis. There is no repair to these boards. Very like computer motherboards.

Model Vizio SV420XVT1A will not power up. The Vizio logo is amber, nothing happens when you press the power button.


You will need to have the set diagnosed as there a number of things could cause this. But I would say you're looking at a power supply or main board problem. It is also possible that your key controller (side buttons) is defective. I take it the TV doesn't turn on with a remote either?

I have an opportunity to buy a Vizio Model SV420XVT1A television that has cracked screen for $100.00. How do I repair something like this or is it even worth the effort?


My suggestion would be not to buy it since the screen is the most expensive part of the TV and is not repairable unless is replaced. The price for a new screen it might exceed the price of a new TV.

Vizio closed captions are with red background! Dish TV or Vizio problem?? Also red pixel lines/flashes!


It is a TV problem and could be the sustain boards or the mainboard.

Most likely it is the Y sustain board but it is recomended to replace Y and Z sustain boards if one is damaged.

The color red is starting to flow throughout the picture.


I have fixed a lot of Vizio TVs. You are getting red pixelation. Some people have green pixelation, too. Usually change main board and main connector cord for fix. Check with vizio and see if it is still under warranty. Some parts have a lifetime warranty. If you call support and give them your model number they may be aware of the problem. It is not your inputs or wiring. It is the boards inside the TV. Let me know how it turns out. Good luck, John.
