In the early days television sets were not made up of much more than a set of rabbit ears on top of a tube enclosed in wood with fuses, knobs, a scanner, and wires. Like everything else in the world today, television sets are a lot more complex. If the electronics involved is of interest to you, understanding the functions of the primary boards in your tv, like the timing control D50ud1, might help you figure out what's going wrong with it.
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 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.
