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 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'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.
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.
