Certain reasons may drive you to repair your television. This includes your device powering itself off or taking a long time to get reception when you turn it on. The good thing is that such problems can be resolved by repairing the TV power supply. The process is not very hard when you have proper guidelines.
There is certain tools that are required for you to do the repair easily. This includes a soldering iron, screwdriver, solder, capacitor, and solder sucker. Check whether your toolbox includes all of this equipment. If they are missing, you may have to visit an electronic shop to buy them. Check to see where exactly the problem is for you to know what should be repaired. For device power supplies, the capacitors are normally the problem and can leak preventing the monitor from being 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.
Check to see the capacitors that are malfunctioning. Capacitors assume the shape of tiny cylinders and only vary in their length and width. Since most of them may appear normal, search for those that have bulged at the surface or are removing a brownish to yellowish liquid on the surface. This means that they have been overheated leading to the problem you are facing. Make sure that no damage is done to copper pads when removing them.
After you have removed all of them, you will have to replace them. Ensure you keep track of the negative and positive polarity as you replace them. Use your soldering iron by marking the negative lead on the board. The negative side has a gray stripe. The capacitors should be installed correctly as they are polarity sensitive. The board is clearly marked helping you to insert them correctly.
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.
Once the fuse has been changed, and the problem has not been fixed, it may be time to substitute the circuit board. This is because if it has any faults, your television may not work properly. However, this process is crucial, and you should know the necessary steps you ought to follow.
