How To Prevent Electrocution When Trying To Repair Your Own TV?

“Where Could I Find An Engineer For TV Repair Near Me?”

“Would He Be Available At This Hour?”

“How Much Would He Charge?”

If these questions bother you too, there are ways to repair your TV on your own which you could try. Although it is always recommended that you hire a professional for the job but if you absolutely need to do it on your own, you can always take the help of online tutorials. Of course for you to be successful in your TV repair, you will have to invest in some tools and equipment and also learn how to use them. You will have to read the instruction manuals carefully and keep them handy whenever you need them.

But be careful when doing those TV repairs because more often than not those tutorials don’t really tell you the whole process of ensuring your safety and protecting yourself from sudden electric shocks. You need to be well aware of what you are doing and also what all risks you are going to expose yourself to. And for that you will have to read on.

First thing to do when you are about to begin a TV repair is to be sure that all the power inputs are shut off. Turn them on only when you are about to test it for the success of any repair done.

When you are in the process of reinstalling the chassis and placing its assemblies, make sure that you restore all the protective devices on it such as the compartment covers and shells and also the nonmetallic control knobs.

The next thing to take care of is the cabinet openings. There should be absolutely no openings or cracks or gaps through which your kids or anyone in your home for that matter can insert fingers and touch the electronic parts within. The spaces between the picture tube and the cabinet mask can be those areas and also the various ventilation slots. Don’t leave the shells and covers just lying on the setup. Tighten the screws in place and make sure that they don’t move or come off easily.

You will also have to do leakage current hot check and for this you will need a leakage-current tester or a metering system. Using an isolation transformer is not advised for this test.

Measuring The Current

For this the unit should be completely reassembled, with no part hanging out and about. You will begin by plugging in the AC line cord into the power outlet. You will then measure the current between a known earth ground and the exposed metal parts first with the unit’s AC switch ON and then OFF. The earth parts comprise the metal water pipe, conduit, etc. and the metal parts include metal cabinets and antennas, handle brackets, screw heads and control shafts. Make sure that the current measured does not exceed 0.5 milliamp. Now you need to repeat the test and for that you will reverse the power-plug prongs in the AC outlet. These were just a few tips on how to prevent electrocution when trying to repair your own TV.
