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.
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.
Once the television has been unplugged from its power source, ensure you place it on a flat area with the screen facing down to prevent any damages. You can then detach all screws that have attached the back panel with a screwdriver. After all of them have been removed, you can detach the back panel by wiggling it a little bit since it is not secured with bolts and then 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.
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.
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.
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.
