Once upon a time televisions were mostly made up of tubes encased in wood, wires, knobs, scanners, and rabbit ears. As with most things, televisions have become much more complicated and technical in today's world. Even though you may not have any plans to become a television repair person, you might still be interested in learning about the boards, such as the T-Con d50ud1, inside LCD tvs, if the science of electronics intrigues you.
If you open up the back of your television set you will probably find the power supply board, or power supply module, on the right hand side of your unit as you are looking at it. It will be the largest and heaviest of all the boards on the back of the set. The purpose of this board is to convert the AC, or alternating current, supply, which can change directions, into DC, or direct current, voltage.
Direct current, or DC, moves in only one direction. The circuit located in the LCD television uses this. You may find the inverter board and the power supply module joined in some televisions. If you're experiencing a lack of power, or only intermittent power, the power supply board may be malfunctioning.
The timing control board, or T-con, is the smallest board in the television. It is pretty much only found in LCD tvs. You'll probably find it under a shield toward the top of the back of the television.
The purpose of the T-con board is to control the circuit and TFT, or thin film transistor, driver. Indications that you have trouble with the T-con board will be vertical or horizontal lines. You might also see a double image, a white screen or no display.
Inverter boards are found along the edge of your television back. Unless you have an LCD television you will not have an inverter board. The purpose of this board is to convert low voltage direct current supplied by the switched mode power supply into high voltage alternate current. This is what lights up the backlights. Sometimes it's included in the power board. If you have a dim screen or the display shuts down, you have a problem with the inverter board.
The main board is also known as the logic board, the digital board, the main module, and the mother board. You will recognize the main board because it is the one with the video and sound outputs and inputs attached to it. The main board takes in signals and converts the analog signals into digital. The main board may be malfunctioning when you don't have sound or color or a picture.
The jackpack or audio receiving board is sometimes separated from the main board. Its function is to take the sound signal to the processor and on to the amplifier which is what drives the speakers on either side of the television. If you don't have sound, or a high pitched one, or channels that change randomly, you need to have the jackpack checked out.
