1. Power-cycle the box

Unplug the Magenta TV box from power, 30 seconds, plug in, wait a few minutes while it boots and reconnects. Standby off/on does not count — it must be the power plug.

2. HDMI and source

Box lights on, screen black? Check the TV input source and reseat the HDMI cable on both ends; try a different HDMI port on the TV. Cables and ports fail far more often than boxes.

3. The line behind the TV

Magenta TV rides on your internet connection. Internet also down? Fix that first — including the postcode outage check. Internet fine but TV dead: Magenta service 0676 200 7777 (daily 8–22) can reset the TV service on their side.

Freezes and pixelation

Recurring stutter at peak times points to the connection between router and box — a LAN cable beats Wi-Fi for TV boxes every time. We install that cleanly if drilling and trunking scare you.

Frequently asked questions

Black screen but the box has lights.

Check the TV source (HDMI input) and swap/reseat the HDMI cable first — the most common cause and the cheapest fix.

TV stutters every evening.

Peak-time load on a Wi-Fi-connected box — connect it per LAN cable or improve coverage. That ends it in almost all cases.

Internet works, TV does not, restart done.

Then Magenta should reset your TV service remotely: 0676 200 7777, daily 8:00–22:00.

Can you help in English?
