Electrocution is a distinct danger you expose yourself to when working with electronics. It’s quite nice to save a few hundred bucks by learning to repair your TV but if it will land you in hospital because you didn’t the necessary precautions, then you would have defeated the purpose of your DIY TV repair project- which is to save some money while at the same time acquiring a new skill that you may or may not use to earn more money.
I’d say that common sense is still the best weapon against any accident involving electronics. Making sure that your test or work area is safe should be a priority and if you think you can’t make it an acceptably safe area to work in, then don’t work in it. Find and go to an area where you can confidently exercise the following precautions:
1. Wear appropriate TV repair clothing. A rubber-soled shoes and gloves are advisable.
2. According to the UK’s Health and Safety Executive (HSE) guideline for “Safety in electrical testing: Servicing and repair of audio, TV and computer equipment”,
The most significant danger to people carrying out electrical testing work is that they might suffer an electric shock. Any simultaneous contact of a part of the body with a conductor that is live at a dangerous voltage, eg one that is connected to the mains supply, while another part of the body is connected to an earth, will result in an electric shock. There is also a risk of burn injuries resulting from arcing when conductors are accidentally
Where possible, the work should be done while the equipment is not connected to any electrical source (i.e., equipment is dead).
3. If you’re on location or in a customer’s home performing your repair service, then you should make sure that you have ample space to work in and that the members of the household are well-briefed about the dangers. Create a temporary barrier around your work area to prevent kids and pets from getting into it. Allow plenty of space to work in so you’ll have enough safe space that you can use to break contact (in case of shock).
4. Never leave an equipment unattended and exposed when it’s in a dangerous condition (e.g. wires exposed)
5. If you’re in a workshop setting (not a home location), then the preceding precautions may also apply. Brief everyone about the dangers and allow for ample work area that is protected from unauthorized access.
6. When in doubt, don’t do it! You can refer to the HSE guidance on electrical testing safety for a more detailed info on the safety precautions you can take. Don’t be afraid to ask questions either!
