A TV is an electronic device that can break or malfunction either because a component wears out or the TV sustains damage from impact. In some cases, repairs require a certified technician, especially with more technologically advanced TVs, such as LCDs, plasma and other flat-panel models. However, it's possible to do some minor repairs yourself with the right tools.

Screen Diagnostic Tool

It's possible for a pixel on an LCD or plasma television to stick or die. When a pixel sticks, a bright coloured dot appears on the screen that is visible on a black screen. A dead pixel is visible on a white screen as a small black dot. In certain cases, a stuck pixel repairs on its own over time, but in other circumstances you need to repair it. Diagnostic tools that come in the form of a DVD work to calibrate and correct issues related to pixel performance. The tool relies on test signals that enable you to adjust the screen settings on your TV to achieve the most desired picture presentation.


The multimeter is a measuring tool. It's generally used to measure volts, currents and ohms, although more advanced multimeter tools also test capacitors, diodes and transistors. According to LCD TV Repair and Plasma TV Repair, a do-it-yourself TV repair guide, the multimeter is a vital TV repair tool for diagnosing a problem with a flat-panel TV. While these tools come in digital and analogue versions, digital multimeters tend to provide more accurate measures than the analogue multimeters.

TV Cables

A fuzzy picture can indicate a problem with the TV cables. A damaged cable wire can lead to poor reception or impact the picture quality. Made Man, an electronics repair guide, suggests checking the cable wires in the back of the TV. If you notice any damage or fraying, then the cords need to be replaced.
