OT-New Vizio LCD TV question

When I play a DVD I get black squares(four or five usually) that show up on the TV screen. Does anyone know what would cause that? Thinking of returning it as it is only a month old. Cost was $1600. Thank You.

Only when watching a DVD??

H, had the problem on about 10 DVD's, some like new, some older. One time my daughter saw one black square on a regular channel.

Dead and Stuck Pixels
Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel.
A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background.
A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed.
Why Are Defects Allowed?
LCD panels are very complicated devices to put together. Each pixel in an LCD monitor is controlled by a number of transistors embedded into sheets of material. For example, a 15" LCD with a resolution of 1024x768 has 786,432 pixels comprised of 2,359296 sub-pixels. Monitors with higher resolutions will have an even greater number of pixels. Even a small impurity in the layers that make up these pixels can result in a pixel defect.
If the manufacturers were to throw out every panel that even had a single defect, the cost to produce LCD monitors would be so high that no consumers would be willing to purchase them. To help them financially produce the panels, the manufacturers have defined a certain percentage of pixels that can be defective but still allow them to sell the panel. This percentage is extremely small, equating to under 1/100th of a percent of the total number of pixels. With improved technologies and techniques, the number of panels being produced with defects is dropping.
Warranties
It is important to find out what the replacement policy is on any LCD monitor prior to purchase. In general, the manufacturer will have a policy with regards to the number of stuck or dead pixels allowed before it can be returned. To make things even more confusing, the location of the pixels can also play an important role in whether the manufacturer will accept it as defective. The number of defective pixels that define a panel as meeting the replacement criteria will also vary with the size and even model of the monitor.
In addition to the manufacturer warranty, look at the replacement policy of the retailer that you are purchasing the monitor from. It is very likely that the policy of the retailer may be better than that of the manufacturer allowing another avenue if the newly purchased monitor has a number of defective pixels.
Conclusions It is very important to be a well informed consumer when purchasing an LCD monitor. Research the warranty and replacement policies from the manufacturer and retailer before making a purchase. Be sure to understand what the terms of the different types and locations of pixel defects mean. All of this can help alleviate frustration if the monitor that you purchase does not meet your standards of quality.

Do yourself a favor and check out the Samsung LCD's.

Visio is one of the worst TV's on the market. People get sucked into the price and fail to take their time and learn about the TV's on the market. Buying a quality TV is almost like buying a house if you want a good one. Do the research and learn about the technology before you go throwing 2k or more on a solid LCD.

Sharp, Toshiba, and Samsung are three outstanding TV's.

I currently have a 37" Toshiba in bedroom and a 52" Sharp in my main living room for HD and movies. Love them both. Never had one problem with either one and the picture quality on both are unreal.

Picked up an Ahanix 32" LCD HD at ecost.com for $505 less a $75 rebate for $430, shipping was only $33. No problems thus far.

In regards to the Samsung lcd's. I have been researching them and I like what I have seen. I am looking for a replacement for my bedroom tv. I only need about a 32". I read that there are problems with the newer models in regards to sound problems. Anyone heard of this?

are these LCD's worth buying the extended warranty? I'm thinking of picking up a TV and not sure if I should spring for an extra 10-20% of the TV for this

No problems with mine. I have a 32" Samsung in the bedroom and It's the only brand I would own, it's awesome.

Harrington, I'm looking at the LN-T3253H. On one of the review websites there are quite a few owners who are complaining of a "sound drop-off". It appears to be related to the HMDI connection. I talked with customer service and they stated that they just send out a dvd with info on how to fix it. I wonder if it's just related to this model.

Samsung BY FAR the best, most reliable, best quality, etc.

Uh oh. that figures. Wife came home yesterday with new flat screen Vizio for the kitchen. I t has 90 day warranty but after reading all the negativity think i will take back and get a Sharp or Magnavox.
