It is 21:40, the owner's TV has gone black, and the ETO is ashore. You can see a power button on a device behind the screen, and a small voice says: just try it. That small voice has taken more yachts offline than any storm. The professional move is to work a ladder - and to know exactly which rung is your last.
The ladder, in order
Work top to bottom. Stop the moment it works, and stop completely at the bottom rung.
- Check the source. Is the source actually playing, or is the film paused, the channel dead, the console asleep?
- Check the input. Is the TV on the right input for the source the panel selected?
- Check volume and mute. The single most common "no sound" cause, in every industry, forever.
- Check the zone. Is the panel controlling the room you are standing in, or the one next door?
- Check the panel and the network. Is the panel awake and responsive? Is the app-controlled tablet actually on the wifi?
- Power-cycle the endpoint - only if your yacht's procedure permits it. That means the TV or the room device, following a documented method. If your yacht has no such procedure, this rung does not exist for you.
Then stop and call the ETO.
The hard stops - no exceptions, no matter who is asking
- Never reboot, power down or open the rack, a server, the matrix, a switch or the control processor.
- Never re-cable, unplug or "just swap" anything.
- Never factory-reset a panel, TV or device.
- Never change network settings, wifi configuration or device names.
- Never let a guest, contractor or visitor into a technical space.
- Never keep trying things in front of a guest because you feel embarrassed.
A guest saying "go on, just restart it" is not authority. The ETO and the captain are authority.
| Fault | Likely cause | Interior can safely try | Call the ETO |
|---|---|---|---|
| One TV black, panel fine | Wrong input, display asleep | Rungs 1-6 | If still black after rung 6 |
| No sound, picture fine | Mute, volume, wrong zone | Rungs 3-4 | If zone and volume are correct |
| Panel dead, others fine | Panel offline | Wait, try the keypad | If it stays dead |
| Every screen black | Matrix, server or rack | Nothing | Immediately |
| Internet down for everyone | Link outage | Nothing | Immediately |
| Burning smell, hot rack, alarm | Serious fault | Nothing - report at once | Immediately, and the bridge |
Onboard Notes
- Learn your yacht's endpoint power-cycle procedure - or learn that it does not have one.
- Whole-boat symptoms are never an interior fix. One room is a maybe; the whole boat is a phone call.
- Escalating early is not failure. It is the job.
- Guessing with a six-figure AV system in front of a guest is how a small fault becomes an outage.
