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.
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.
You should then determine the location of the circuit board on the device by following closely the board connected to the power cord. Detach all the connectors and screws from the board with a screwdriver. Make sure that you clearly note how they are connected for reattachment to be easy. It will be better if you take images to prevent you from being confused when reattaching them. After the screws and connectors have been detached, you can take away the circuit board.
Locate the faulty capacitors. They are cylinder-shaped and vary in width and height. Most of them appear normal and therefore look for ones with a brown-yellow liquid coming from the top, or it has bulged at the top. This is an indication that the capacitors have overheated and are the cause of the fault. Remove them ensuring that you do not damage copper pads.
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.
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.
