Panasonic TV 'An Error has been detected and recovered' Fix

What it means

'An Error has been detected and recovered' on a Panasonic TV is a pop-up that the TV is passing through from a connected source device — most often a cable or satellite box, a Blu-ray player, or a games console.
The TV itself didn't generate the message; it's just displaying what the source sent.
The phrase means the source device noticed an internal error, handled it on its own, and is letting you know.
Most cases clear by power-cycling the source device; if it keeps appearing, the source device is the place to look — not the TV.

Affected Models

Panasonic Viera LED TVs (TX series, 2015 onwards)
Panasonic OLED TVs (GZ, HZ, JZ, LZ, MZ ranges)
Panasonic Smart TVs running My Home Screen 4.0–8.0
Older Panasonic plasma sets pairing with cable / satellite boxes
Any Panasonic TV with HDMI input from a set-top box, Blu-ray player, or console

Common Causes

Source device (cable box, satellite receiver, Blu-ray) had an internal error
HDMI handshake glitch between the source and the TV
Source device firmware bug that's been fixed in a newer release
Loose HDMI connector at the source end — signal dropping briefly
Source device overheating and throwing a recoverable error
Cheap or damaged HDMI cable corrupting the signal
Power supply issue on the source side (failing wall adapter)
Source on the same circuit as a noisy appliance — transient interference

How to Fix It

Identify which source is sending it.

Switch through the HDMI inputs one at a time and watch for the pop-up.
It only appears on one source — that's the device you need to focus on (the cable box, console, Blu-ray, etc.).
Once you know which source is throwing it, the rest of the troubleshooting belongs to that device, not to the TV.
Power-cycle the source device.

Unplug the source device (cable box, satellite receiver, Blu-ray, console) from the mains for one full minute.
Plug back in.
Most one-off internal errors clear with a hard restart on the source side.
If the pop-up doesn't return after the restart, no further action needed.
Reseat the HDMI cable both ends.

Pull the HDMI cable from the source device and from the TV.
Push it back in firmly until you feel the click.
A loose connection causes brief signal drops that the source device flags as an error.
If you're using HDMI through a soundbar or AV receiver, reseat both links — source-to-receiver and receiver-to-TV.
Try a different HDMI cable.

Cheap or damaged HDMI cables corrupt the signal in ways the source device picks up as an error.
Swap to a known-good Ultra High Speed HDMI cable (for 4K HDR sources) or High Speed (for 1080p).
If the pop-up stops with the new cable, the original cable was the cause.
Update the source device's firmware.

Many 'detected and recovered' messages come from firmware bugs the source device's manufacturer has since patched.
Check the support site or settings menu of the source for a software update — cable boxes update over the air, consoles via system settings, Blu-ray players via internet or USB.
Apply the latest firmware and the pop-up usually goes.
Check the source device's vents and surroundings.

If the source device sits in a closed cabinet or has dust over its cooling vents, it may overheat and throw recoverable errors.
Pull it forward, give it space for airflow, vacuum dust off its top and sides.
For older boxes, even a five-minute cool-down helps.
Move to a different HDMI port on the TV.

Although the message comes from the source, swapping to a different HDMI input on the TV sometimes clears it — different ports can have slightly different HDCP behaviour.
Move the source's HDMI cable from HDMI 1 to HDMI 2 (or whichever is free) and watch for the pop-up.
Contact the source device's manufacturer.

If the pop-up persists after a power cycle, a fresh cable, a firmware update, and an HDMI port change, the source device itself has a fault.
Contact the maker of the cable box, console, or Blu-ray for warranty repair or replacement.
The TV is innocent here; chasing this through Panasonic support won't reach the right team.

When to Call a Professional

This is owner-territory and the TV itself almost never needs a technician.
Call the manufacturer of the source device (your cable provider, Sky, Virgin, the Blu-ray brand, the console maker) if the pop-up keeps appearing on the same source even after a power cycle and a different HDMI cable.
The TV is just the messenger here — Panasonic support can't fix an error that's coming from another company's hardware.

Frequently Asked Questions

Is 'An Error has been detected and recovered' a problem with my Panasonic TV?

No — and that's the most important thing to know.
The TV is just acting as a screen for whatever device is plugged into the HDMI port at the time, and the pop-up is coming from that source device's own software.
Panasonic's support page for this exact message even says so: the message originates from the connected source, not from the TV.
The recovered part is the clue — the source device noticed something wrong, handled it itself, and is informing you that everything is OK now.
If the pop-up keeps appearing, the source device's manufacturer is the right place to start; the TV doesn't need looking at, doesn't need a firmware update, and doesn't need a service visit for this message alone.
