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 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.
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.
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.
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.
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.
