How to remove a large black dot on a TV screen

When you buy a new HDTV, it is essential that you look for any instances of dead pixels. Dead pixels are commonly found as static grey or black spots on your television screen. Initially, these spots may be tiny, but they will grow over time as more and more pixels become faulty. Although there are no fixes you can do for this at home, there are a few troubleshooting techniques you may try before sending your HDTV or plasma TV for repair.

Turn off your television. Unplug the power cord from the television for a few hours. Powering off the television may force a pixel to become "unstuck" upon plugging the television back in, returning it to a working status.

Verify that the problem is not with any of your components that are plugged into your television, such as your cable box. Unplug all the cables leading into your television and component. Reconnect them to ensure a secure connection. A loose connection may cause distorted images on your television akin to a dead pixel.

Contact your television's manufacturer or a repair shop to schedule a repair. Repairing a dead pixel will require the entire screen to be replaced on your television.
