In the early days television sets were not made up of much more than a set of rabbit ears on top of a tube enclosed in wood with fuses, knobs, a scanner, and wires. Like everything else in the world today, television sets are a lot more complex. If the electronics involved is of interest to you, understanding the functions of the primary boards in your tv, like the timing control D50ud1, might help you figure out what's going wrong with it.
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, 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 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.
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.
