Panasonic TVs, including Viera and the newer Android/Google TV models, are dependable, but they occasionally display error codes or warning messages. Most Panasonic TV error codes relate to network connectivity, app servers, or a software glitch — and the majority can be resolved at home. This guide lists the common codes, explains them, and gives you clear fixes.
Quick Answer
For most Panasonic TV error codes, start with a power-cycle: unplug the TV for 60 seconds, hold the power button 10-15 seconds while unplugged, then plug back in. Restart your router for connection codes, clear or reinstall the app for streaming errors, and update the firmware to fix system glitches. Persistent hardware codes need a technician.

| App Error / 3000 | App or content server fault | Clear cache, reinstall app, update firmware |
| H / Blink codes | Hardware self-diagnosis (blink count) | Count blinks; power-cycle; note code for service |

When to Call a Technician
A repeating blink-code on the standby LED with no picture, backlight failure, or errors that return after a factory reset usually mean a power supply or panel hardware fault. These require professional service. If repair is uneconomical on an older set, compare upgrades with our best smart TV in India guide and see how to sell your old TV for the best price.

Frequently Asked Questions
How do I factory reset a Panasonic TV?
Go to Menu > System > System Reset (or Shipping Condition), then confirm. This clears most software error codes.
What do the blinking lights on a Panasonic TV mean?
They are diagnostic blink codes. Count the number of blinks and note the pattern — it identifies the failing component for a technician.
Why won’t my Panasonic TV connect to Wi-Fi?
Weak signal, wrong password, or DNS issues are common. Restart the router, re-enter the password, and try a manual DNS of 8.8.8.8.
Why does my Panasonic TV say software update failed?
The update was interrupted, often by an unstable connection. Retry on a strong network or perform a USB firmware update from Panasonic’s support site.
