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 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, 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 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 purpose of the T-con board is to control the circuit and TFT, or thin film transistor, driver. Indications that you have trouble with the T-con board will be vertical or horizontal lines. You might also see a double image, a white screen or no display.
You'll find the inverter board on one edge of the back panel. You won't find it at all unless you have an LCD tv. The purpose of the inverter board is to convert the low voltage DC that is supplied by the switched mode power supply. It turns the low voltage into high AC. This is what causes the backlights to light up. The inverter board and the power board are sometimes found together. You may have a problem with an inverter board when you see a dim screen, or when the display completely shuts down.
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.
