Error 105 on Hisense TVs

What error 105 usually means on a Hisense TV

On some Hisense TVs, “error 105” is linked to a DNS resolution problem: the TV is connected to the network, but can’t translate the site/service name into an IP address, so pages or preinstalled apps won’t load. This matches browser messages such as net::ERR_NAME_NOT_RESOLVED (-105).

A very common pattern is:

• Netflix/Prime may work, but the browser or other system apps fail.
• The error appears when creating an account or opening services that rely on a specific domain.
• Wi-Fi shows as “connected,” but web content stays blank or returns 105/(-105).

How to fix 105 step by step

Because 105 typically points to DNS, the most effective approach is to tackle router + DNS + saved network in this order:

1. Full power cycle (TV + router)
   • Unplug the TV for 60 seconds.
   • Unplug the router for 30–60 seconds, then power it back on.
   • Once the router is stable, turn the TV on.
2. Forget Wi-Fi and reconnect from scratch
   • Remove the saved network and enter the password again.
   • If you can, avoid “mixed” networks and try the 2.4 GHz band if 5 GHz is weak (or vice versa).
3. Change DNS (the key point for 105)
   • If your Hisense allows it, set manual DNS (for example 1.1.1.1 / 8.8.8.8).
   • If it doesn’t, change DNS on the router (this affects all devices).
   • The ERR_NAME_NOT_RESOLVED error is specifically associated with name resolution (DNS) failures.
4. Test with an Ethernet cable (to rule out Wi-Fi)
   • Connect directly to the router via Ethernet and repeat the browser/app test.
   • If it works over cable, the issue was Wi-Fi stability or interference.
5. Update the TV system
   • Check for a firmware update in Settings.
   • With “odd” network errors (only some apps), an update can fix network libraries or certificates.
6. Reset network settings / factory reset (only if it still persists)
   • First, reset network settings (if that option exists).
   • If nothing works, do a factory reset.

If the error you see is literally net::ERR_NAME_NOT_RESOLVED (-105) inside the TV browser, it almost always goes away once you fix DNS (manual on the TV or on the router) and rebuild the saved connection.
