Once upon a time televisions were mostly made up of tubes encased in wood, wires, knobs, scanners, and rabbit ears. As with most things, televisions have become much more complicated and technical in today's world. Even though you may not have any plans to become a television repair person, you might still be interested in learning about the boards, such as the T-Con d50ud1, inside LCD tvs, if the science of electronics intrigues you.
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.
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 known as the logic board, the digital board, the main module, and the mother board. You will recognize the main board because it is the one with the video and sound outputs and inputs attached to it. The main board takes in signals and converts the analog signals into digital. The main board may be malfunctioning when you don't have sound or color or a picture.
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.
