How to Protect Your TV During Load-Shedding
Load-shedding does not just interrupt your viewing. The repeated off-and-on cycles, and especially the voltage spikes when power is restored, are a leading cause of TV power supply failures in South Africa. The encouraging part is that protecting your TV is mostly about a few inexpensive habits and one or two well-chosen pieces of equipment. Here is what actually works, based on the damage patterns we see in the workshop every week.
Unplugging: still the best protection
No device protects your TV as completely as removing it from the wall socket. When your schedule says load-shedding is coming, switch the TV off and pull the plug, or switch off the wall socket if it has a switch. After power returns, wait five to ten minutes before reconnecting, because the first minutes of restored supply are when spikes and fluctuations are most likely. Make it a household habit, the same way you lock the front door.
Choosing a surge protector that earns its keep
For the surges you cannot plan around, a plug-in surge protector is worthwhile insurance. Choose a reputable brand with a stated surge rating and, ideally, an indicator light that shows the protection is still active. Remember that protectors are sacrificial: every surge they absorb uses up capacity, so replace them after a known major surge or every few years in a heavy load-shedding area. A cheap multiplug with no surge rating protects nothing.
UPS and inverter backup for your TV
A small UPS or trolley inverter keeps the TV, decoder and router running through an outage, and it also smooths the switchover so your equipment never sees the raw restoration surge. Check the wattage of your TV and connected devices against the unit's continuous rating, and favour units with a pure sine wave output for sensitive electronics. This is the most comfortable option, though the unplugging habit still costs nothing and remains worth keeping.
A simple load-shedding routine for your lounge
Put the TV, decoder and sound equipment on one surge-protected multiplug so a single switch isolates everything. Before scheduled outages, power down and switch off at the wall. After restoration, wait a few minutes, then reconnect. Once a month, glance at the surge protector's indicator light and replace the unit if protection has expired. If your TV ever behaves strangely after an outage, restarting, clicking or refusing to start, have it checked before the fault gets worse.

Is it enough to just switch the TV off with the remote?
No. Standby mode leaves the power supply connected and exposed, so a restoration spike can still damage the TV. Switching off at the wall, or unplugging entirely, is what actually isolates the set. The remote only puts the TV to sleep; it does not disconnect anything.
Do I need a UPS specifically for my TV?
Need is a strong word, but a correctly sized UPS or inverter is the most convenient protection because it bridges outages and buffers the restoration surge. If that is outside the budget, disciplined unplugging plus a quality surge protector covers the biggest risks at a fraction of the cost.
My TV survived load-shedding for years. Why worry now?
Surge damage is cumulative. Each spike stresses capacitors and protection components a little more, and a supply that shrugged off surges when new becomes fragile as it ages. Many of the dead TVs we repair worked fine through years of outages before one ordinary restoration finally pushed a worn component over the edge.
