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 look at the back of your tv set, once it's been opened up, you will see the power supply board, also called the power supply module, sitting on the right side. This will be the biggest and heaviest of the boards on the back panel. The job of the power supply board is to convert the AC, alternating current, supply, which changes directions, into a DC, direct current, voltage.
The direct current will only move in one direction. This is what the circuit in LCD televisions uses. Depending on the model you have the power supply module and the inverter board may be combined. If you're not getting any power, or only intermittent power, the power supply board may be to blame.
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 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 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.
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.
