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 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.
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.
