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 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 T-Con board is there to control the TFT, thin film transistor, driver and the circuit. If you're experiencing horizontal or vertical lines you may be having trouble with the timing control board. Other indications are a white screen, a double image, or no image at all.
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 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.
