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.
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.
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.
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 you have removed all of them, you will have to replace them. Ensure you keep track of the negative and positive polarity as you replace them. Use your soldering iron by marking the negative lead on the board. The negative side has a gray stripe. The capacitors should be installed correctly as they are polarity sensitive. The board is clearly marked helping you to insert them correctly.
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 the issue has not been resolved, consider replacing the circuit board. If the circuit board has been destroyed, your device will not be able to work effectively. Prior to replacing it, you need to know the correct steps to be followed. This prevents you from further damaging your television.
