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.
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.
Remove the device from its powering source and place it on a working area that is flat ensuring that the screen faces down to minimize damage. All of the bolts should then be loosened by use of a screwdriver to remove the back panel. Once they are loosened, separate the back panel from the main unit by wiggling it and safely keep it aside.
Check where the circuit board is by keenly following its connection to the power cord. You should then loosen the bolts and connectors attached on the board with the help of a screwdriver. You ought to take note on their connection so that you correctly reattach them. Take pictures of the connection to help you during reattachment to prevent you from forgetting. Once the connectors and bolts are loosened, disconnect 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.
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.
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.
