Your television may not be able to function properly causing you to do check ups where the fault is. If it as an issue with power, it may exhibit characteristics such as shutting itself off or using a longer time frame to get reception as soon as you power it. This is not a very big challenge as it can be solved by TV power supply fixing. Here are the steps you ought to follow.
There are a number of tools you will need to effectively do the job. They include a capacitor, soldering iron, solder, screwdriver and a solder sucker. Confirm that your toolbox has all these items, and if not, you will have to go to the store. You should first determine if the problem is really what you want to repair. In television electric supplies, capacitors normally go bad causing them to leak and bulge hence the monitor will not get power.
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.
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.
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.
If none of these solves the problem, your last option is to replace the main circuit board of the device. This is because if it is damaged, the television would not work correctly. Before doing this, you should have guidance on how it should be replaced so that you do not cause further damage to the device.
