Problems With Vizio LED Televisions

Television picture quality improves every year. As of July 2011, the best possible picture comes from an LED high-definition television. Vizio is one company that produces LED TVs. Occasionally, owners of Vizio LED TVs might run into setup or functionality problems, but most of these types of issues can be easily resolved.

LED TVs come in flat panel displays.


LED technology is new to the television market. It's used in conjunction with LCD technology. Previously, LCD TVs used florescent lamps to light the LCD display. This produced a clear picture, but it also reduced some of the deep tonality found in some other technologies like plasma. The reason for this was that the fluorescents needed to remain "on," which caused light to escape, and as a result, deep black colors suffered. By lighting an LCD TV with LED, this problem was rectified.

No Signal

One common problem type is the Vizio TV displaying a "No Signal" message. This message is meant to indicate to the user that the TV can't find a content source. When this occurs, start by determining what type of media you're trying to play. Are you trying to watch cable? Are you trying to view a DVD? Next, press the "Input" button on the remote control and toggle to the appropriate input source. Also, ensure that all the devices you're trying to use are turned on, appropriately connected and running.

Image Quality

Poor image quality is another common issue. Your LED TV is a top-of-the-line piece of media equipment, but to receive the best image possible, you'll need other items to work in conjunction with it. For the best results, you'll need a cable subscription with an HD package, a Blu-ray player and an HDMI cable. If you're missing one of these items, your picture quality will suffer. Also, remember if you're viewing cable with an HD package, make sure you're tuned into an HD broadcast.


A less common issue is the appearance of “dots.” This is often mistaken as a manufacturer's defect, but it's not. If there are dots on your screen that appear dark or continually lit, this is just part of the TV's technology. While it's annoying, it unfortunately occurs sometimes with LED TVs. As Visio doesn't view it as a “defect,” there's no direct way to rectify the issue. However, if you wait, the pixels should eventually display correctly.
