There are a number of reasons why you might want to do a repair. One of it is that your television may be powering off on its own or it may take a long duration to get reception as soon as it is turned on. Lucky enough, this kind of issue can be solved by TV power supply repair. Before beginning, below are some of the crucial steps you need to look into.
You will need different tools to help you realize the task easily and quickly. Check if a capacitor, screwdriver, soldering iron, solder sucker, and solder are in your toolbox. If you do not have one, go to an electronics store to buy what you do not have. Use them to open the device and determine what is causing the issue. In most cases, the capacitors are the fault, and if they have leaked, the screen will not be powered.
After you have unplugged the television from the power source, place it with the monitor facing down on an area so that the screen is not damaged. Loosen all of the screws that you see on the back panel by use of a screwdriver. Once you have removed all of them, remove the back panel of your device and place it aside. You may have to wiggle it as there are no bolts securing it.
Check where the circuit board is by keenly following its connection to the power cord. You should then loosen the bolts and connectors attached on the board with the help of a screwdriver. You ought to take note on their connection so that you correctly reattach them. Take pictures of the connection to help you during reattachment to prevent you from forgetting. Once the connectors and bolts are loosened, disconnect the circuit board.
Find the malfunctioning capacitors. They are shaped like small cylinders and are different in height and width. Probably all of them appear normal. Search for those that have a brown to yellow fluid at the top or seem to have swollen at the surface. Such an appearance indicates that they have been overheated hence causing the problem. While you are getting rid of them, make sure that the copper pads are not destroyed.
After all of the bad ones have been gotten rid of, replacement with new ones ought to be done. Make sure you note the positive and negative polarity while doing the replacement. Mark negative leads using a soldering iron on the board. The negative side normally has a stripe colored in gray. The capacitors need to be correctly installed since they are polarity complex.
Once you have done the replacement, the device should be reassembled, and then the power checked. After the connectors have been interchanged and the bolts and back panel reattached, determine if the fault has been rectified. A power surge will definitely cause the fuse to blow. If you notice that the problem has not been fixed, consider checking its fuse. Ensure that you replace it with an appropriate one.
If the issue has not been resolved, consider replacing the circuit board. If the circuit board has been destroyed, your device will not be able to work effectively. Prior to replacing it, you need to know the correct steps to be followed. This prevents you from further damaging your television.
