What Does a T-Con Board in a TV Do?

What Does a T-Con Board in a TV Do?

Televisions contain various complex parts that are imperative to the device’s overall function. The main component that falls into this category is the T-Con board. To better understand this impactful electronic device, read on to learn everything you need to know about the T-Con board in a TV.

What is a T-Con board?

T-Con stands for timing controller. Professionals may also refer to T-Con boards as a “controller board” or “control board.” It is the smallest board inside an LCD TV.

Where is a T-Con board located?

Manufacturers typically only include T-Con boards in LCD televisions.

What Does the T-Con Board in a TV Do? 

A T-Con board is responsible for generating the horizontal and vertical timing panel signals as well as providing panel bias and enabling signals. It controls the logic signal of gate and serves as a source for driving the thin-film transistor (TFT) liquid crystal display (LCD).

Simply, this board is in charge of video processing. It will convert the video signal into one that an LCD panel can interpret.

T-Con board components

The main part of a T-Con board is a T-Con chip. This chip receives pixels from the scaler in a sequential format before driving the LCD collection’s individual pixel components. This interface takes place internally. As such, there is a wide number of connections that can take place. Between a scaler and a T-Con board, there are often many parallel links—contrary to a typical monitor-source connection which usually requires just one single cable to carry an entire image.

Common T-Con board faults

If there is an issue with your T-Con board, it may impact your TV’s image quality in several ways. Common symptoms of T-Con board failure include:

  • Double image
  • Display distortion
  • White display
  • Various vertical or horizontal lines across a screen
  • No display
  • Black and white vertical bars across a screen
