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.
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 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.
You will find the inverter board at the back along the television's edge. If you have any tv other than an LCD, there will be no inverter board. This board is on the tv in order to convert the low voltage direct current, that the switched mode power supplies, into high voltage alternate current. Backlights are lit up with this. Inverters boards are sometimes combined with power boards. If your inverter board goes bad, you may see a dim screen or a display that shuts down entirely.
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.
