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 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.
The direct current will only move in one direction. This is what the circuit in LCD televisions uses. Depending on the model you have the power supply module and the inverter board may be combined. If you're not getting any power, or only intermittent power, the power supply board may be to blame.
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 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 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.
