TV Power Supply Fixing Guide

By Ryan Sullivan


Certain reasons may drive you to repair your television. This includes your device powering itself off or taking a long time to get reception when you turn it on. The good thing is that such problems can be resolved by repairing the TV power supply. The process is not very hard when you have proper guidelines.

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 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 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.
