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.
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 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 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 called the main module, the digital or logic board, or the motherboard. The video and audio inputs and outputs are attached to it. The main board converts signals from analog to digital. If you're having trouble with the sound or the color, it may be the main board.
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.
