Overview
- Modern LED, QLED and OLED televisions are highly vulnerable to storm‑driven voltage spikes that can burn internal boards even without a nearby strike.
- Technicians advise full disconnection: unplug the TV, remove HDMI links to decoders or consoles, and detach antenna or cable‑TV leads.
- Routers and modems are frequent casualties because surges can enter through telephone or internet coax lines and propagate over Ethernet to connected devices.
- Practical steps include unplugging the router, removing internet or phone cables, avoiding Ethernet use during the storm, and waiting a few minutes after activity subsides before reconnecting.
- INTI warns basic stabilizers offer limited protection; quality UPS units or IRAM‑rated surge protectors improve safety but are not foolproof, and TV repairs can cost an estimated 40%–70% of the set’s value.
