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 look at the back of your tv set, once it's been opened up, you will see the power supply board, also called the power supply module, sitting on the right side. This will be the biggest and heaviest of the boards on the back panel. The job of the power supply board is to convert the AC, alternating current, supply, which changes directions, into a DC, 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 T-Con, or timing control board, will be the smallest board on the panel. LCD televisions are the only ones that have them. These boards are usually covered by a shield and are located on the top back of your panel.
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 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.
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.
