There was a time when television sets were not comprised of much more than a tube encased in wood, fuses, wires, a scanner, some knobs, and a set of rabbit ears. Like most things in today's world, televisions are more complicated now. You may never want to be a television repair person, but if you have any interest in electronics, it can be instructive to learn about the primary boards, like the T-Con d50ud1, found in LCD tvs.
When you open the back of an LCD television, you will most likely find the power supply module, or power supply board, located on the right side the back when you're looking at it. The power supply board is going to be the heaviest and biggest board on the back of your set. The function of the power supply board is to convert alternating current supply, or AC, which has the ability to change directions, to direct current voltage, DC.
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 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 function of the timing control board is to control both the circuit and the TFT driver. If the T-Con board malfunctions you might see horizontal or vertical lines or a double image. There might also be just 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 motherboard, the logic board, the main module, and the digital board. This is going to be the board on the back of the television that has the sound and video inputs and outputs attached to it. The main board is what takes in the signals and converts analog into digital. If you don't have color or sound, have vertical lines, or no picture, the main board may be the culprit.
The audio receiving board or jackpack can be separated from the motherboard. The jackpack moves the sound signal to a processor and then to the amplifiers that are on either side of your television. If you can't get any sound, or hear a high pitched tone, the jackpack can be the culprit. You should check out the jackpack if the channels start to change randomly.
