My Samsung LED Has Dead Pixels

Most consumers don't understand that a light-emitting diode television is really a liquid crystal display television with LED backlighting. The backlighting serves to provide the sub-pixels colored red, green and blue with the power needed to deliver the image to the screen. Each pixel consists of these three sub-pixels. Sometimes, when you get your new Samsung LED television out of the box and hang it on the wall, you might experience dead pixels.

Video of the Day

Analog TVs had single resolution; not so with HDTVs offering multiple resolution formats.

Dead Pixels

Dead pixels happen when electrical voltages coming through the transistors to power the sub-pixels aren't recognized or received. Because the pixel, a small dot on the screen, helps define image resolution and provide color to what moves across the screen, it may be hard to avoid seeing a dead pixel when it's showing up as a black pimple on your favorite actor's nose.

Manufacturers and Dead Pixels

Most manufacturers won't replace a television without a set number of pixels burnt out or not working. They consider it perfectly normal to have a few pixels dead, even when the television is brand new. Unless you have significant pixel damage, don't expect the majority of manufacturers to be willing to replace your television. It takes more than five to seven dead pixels to get a response from a manufacturer.

Fixing Stuck Pixels

Pixels may not be dead, but stuck instead. Revive them by placing a microfiber cloth on the bad pixel spot and gently hold the cloth in place with your thumb. Activate the television's power supply and see if this doesn't correct the problem. Another solution is to take the microfiber cloth and gently swipe down the screen of the television. Start in one corner and work you way across the whole screen, lightly pressing as you go.


The Samsung LED television comes with a warranty and as early as 2005, Samsung made a commitment to not deliver televisions with bad pixels. In the case of a television with a bad pixel, especially ones less than a year old, contact Samsung or the place you purchased the television. Most electronic stores will exchange your television with a new one if you are not satisfied with your purchase and you return the television during the "exchange period."
