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.
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.
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.
The next step is to locate where the circuit board is by following the board that the power cord is linked to. Disconnect the screws and connectors by using a screwdriver from the board. Ensure you note where they all came from as you will have to reattach them as they were. It is imperative you take pictures so that you do not get confused during reattaching. After the connectors and screws are unattached, remove 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.
Reassemble the device and the check power. After replacing connectors, back panel and screws, confirm whether the issue has been resolved. A power surge probably may have caused the fuse to blow. If the problem is not yet resolved, test the fuse. You will have to look for the appropriate fuse and replace it with the old 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.
