If a factory reset doesn’t fix error 600 on your Sony TV (usually a streaming‑app or network‑reference code such as Netflix error 600), it means the problem has moved beyond simple software or account‑level issues into network, router, or possibly hardware territory. At that point, the next steps are more systematic checks and, if needed, service‑level intervention.
1. Confirm the exact meaning of error 600
On Sony Bravia TVs, error 600 often appears inside Netflix or other streaming apps when:
-
The TV has an internet connection but the app cannot refresh or reach the service properly.
-
The error may also show in some older models as a network‑related reference code that appears when the TV has internet but cannot access certain servers.
If the error goes away from other devices (phone, laptop, tablet) on the same network, the fault is likely tied to the TV’s network stack or Wi‑Fi hardware.
2. Restart the router, modem, and TV again
Even after a factory reset, intermittent router or DNS glitches can still cause 600‑type errors.
-
Unplug the router and modem for 60 seconds, then plug them back in and wait for full lights.
-
Unplug the TV for one full minute, then plug it back in.
-
After both return, open the streaming app again and see if the 600 error persists.
This clears temporary router‑session‑tables, DHCP issues, and app‑caches that may not have fully reset with the TV alone. If the code vanishes, the root cause was a router / ISP or router‑to‑TV handshake glitch.
3. Re‑connect to the network and test the apps
A factory reset wipes the TV’s settings, so you must treat it like a new setup.
-
Go to Home → Settings → Network and reconnect to Wi‑Fi or Ethernet.
-
Re‑enter the Wi‑Fi password carefully and then open the streaming app that showed error 600.
-
If the app still shows 600, try signing out of the account (Netflix, etc.), then signing back in, because the factory reset does not always fully clear app‑layer tokens.
If the error stays, the TV may still be reaching the internet, but either the app is blocked by the router/firewall, or the TV’s Wi‑Fi hardware is marginal.
4. Check router‑side restrictions and DNS
Persistent 600‑type errors after a factory reset often trace to router configuration, not the TV itself.
-
Log into your router admin page and check for:
-
MAC‑address filtering or Access Control that might block the TV.
-
Aggressive parental controls or site‑blocking that includes Netflix or related domains.
-
DHCP or firewall settings that interfere with streaming‑service traffic.
-
-
Consider changing the router’s DNS to Google DNS (
8.8.8.8/8.8.4.4) or Cloudflare DNS (1.1.1.1/1.0.0.1) and restarting the router.
If the TV shows 600 before or after DNS changes, the Wi‑Fi or network‑path issue is still present.
5. Test with Ethernet or a different network
If the TV is on Wi‑Fi:
-
Plug it into the router with an Ethernet cable (if the TV has a LAN port) and repeat the app test.
-
If the 600 code disappears over Ethernet, the fault lies in the TV’s Wi‑Fi module or router‑Wi‑Fi configuration, not the software.
Alternatively, connect the TV to a different network (mobile hotspot or another Wi‑Fi) and see if the error 600 repeats. If the code vanishes on the other network, your primary router or ISP is the culprit; if it stays, the TV itself is more likely the problem.
6. When hardware‑level repair is likely
If:
-
Multiple factory resets
-
Router‑restarts and DNS changes
-
USB‑to‑Ethernet or mobile‑hotspot tests
still leave the TV flashing error 600 or repeatedly failing to load the app, the TV may have:
-
A failing Wi‑Fi module or mainboard that cannot sustain stable traffic to the server.
-
Corrupted firmware or app‑partition data that is not fully cleared by a normal factory reset.
In that case, the next realistic step is professional diagnosis and repair or Sony service (if under warranty). A technician can either:
-
Perform a deeper firmware reload or partition‑level erase, or
-
Replace the Wi‑Fi / mainboard section if testing shows it is hardware‑faulty.
For Sony TV owners in Nairobi or similar areas, a factory reset is only the first line of defense against error‑600; if the code persists, treating the network setup, router, and Wi‑Fi hardware as possible culprits gives the best chance of a clean, long‑term fix.
