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.
You should then determine the location of the circuit board on the device by following closely the board connected to the power cord. Detach all the connectors and screws from the board with a screwdriver. Make sure that you clearly note how they are connected for reattachment to be easy. It will be better if you take images to prevent you from being confused when reattaching them. After the screws and connectors have been detached, you can take away 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 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.
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.
