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 moves in one direction only and is what the circuit inside the LCD television uses. In some televisions the power supply board and the inverter board are joined together. If the power supply board malfunctions you'll get no power or intermittent power.
The T-Con, or timing control board, is the board on the television that is the smallest. Only LCD tvs use it. You should look for it under its shield which will be on the top back of the television.
The T-Con board is there to control the TFT, thin film transistor, driver and the circuit. If you're experiencing horizontal or vertical lines you may be having trouble with the timing control board. Other indications are a white screen, a double image, or no image at all.
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.
Sometimes the audio receiving or jackpack board is separated from the mother board. The jackpack takes the sound signal to the processor and moves it to the amplifier. The amplifier drives the speakers located on both sides of the television. The jackpack may be your problem if you experience no sound, high pitched sound, or channels that randomly change.
