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.
Remove the device from its powering source and place it on a working area that is flat ensuring that the screen faces down to minimize damage. All of the bolts should then be loosened by use of a screwdriver to remove the back panel. Once they are loosened, separate the back panel from the main unit by wiggling it and safely keep it aside.
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.
Once you remove the faulty ones, use the new ones to replace them. Take note of the positive polarity and negative polarity when substituting them. You should then indicate the negative leads that are on the board using the soldering iron. The negative section is characterized by a grey stripe. Since the capacitors are polarity sensitive, make sure they are installed well.
After replacement, you ought to reassemble your television to check power. When you have substituted the connectors and have reattached the back panel and the bolts, check if the problem has been rectified. A power surge is the likelihood of the fuse blowing. Therefore if the issue has not been settled, check the fuse. Look for a suitable fuse for your device for replacement.
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.
