Selecting a Power Supply Board for Your TV
Every television set has a power supply. This apparatus is responsible for providing electric power to the TV. The power board converts the electrical current from the power grid to the correct electric currency, frequency, and voltage required by the television.
How To Select The Right Power Board?
Every Samsung TV can only work properly with a specific power supply board. If you are looking for a replacement board for a TV you currently own, you need to ensure you are shopping for the correct repair unit.
- By part number:To ensure you are looking for the right replacement board, you will need to obtain the part number of the existing power supply in your TV. This may require that you open the back of the TV in order to access the board and read the part number printed on it. You may want to take a photo of it for easy reference once you have replaced the back cover.
- By model number:Another way to narrow down the specific power board you need for your television would be to shop by manufacturer and model number. This process will require you to obtain the model number of your television. Most manufacturers have a web site where you can enter your model number and search for replacement parts.
How Do I Determine If My Power Supply Is Bad?
LCD TVs have several parts that can go bad and prevent the television from operating properly. It is always good to try to diagnose the issue prior to purchasing any replacement parts and attempting the repair. Some of the symptoms that may indicate a bad power supply in need of repair include:
- The Samsung TV does not power up or it immediately shuts down after you attempt to turn it on.
- Upon attempting to turn on the LCD television, you hear clicking but it never comes on.
- Any flickering, dimming, or unusual colors and color bands across the screen is another sign.
A lot of times the point of power failure on the board are the capacitors. The capacitors' function is to store and alter electric charge as per the device specifications. Blown out or swollen capacitors can no longer function properly and need to be replaced. Sometimes it may be simpler to replace the entire power supply board rather than attempting repairs.
