TV Power Supply Fixing Guide

By Ryan Sullivan


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.

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.

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.
