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.
Locate the faulty capacitors. They are cylinder-shaped and vary in width and height. Most of them appear normal and therefore look for ones with a brown-yellow liquid coming from the top, or it has bulged at the top. This is an indication that the capacitors have overheated and are the cause of the fault. Remove them ensuring that you do not damage copper pads.
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.
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.
