SMART TV TROUBLESHOOTING

TV cant connect to wi-fi network.
Steps to fix this issue:
• Set on your wi-fi router/access point WPA or WPA2 encryption. WEP is not supported.
• Set on your wi-fi router DNS to
8.8.8.8 (Google DNS server)
• If above does not help, try to upgrade software again.
2. Entering AQUOS NET+ is not possible
• Most probable cause may be missing or wrong MAC address.
Steps of test validity of MAC address:
1. Press
MENU + 1147 to enter factory menu
2. Go to 11 SW Information and press OK (Pic.1)
3. Check item 10 Sraf Valid MAC
4. If there is (OK), it means everything is ok (Pic. 2)
Note: It may take few seconds until “OK” shows after turning TV on.
5. If there is (NG), means either MAC address is missing or is not supported by current SDK (Pic.3).
In case of NG test result:
1. Check 7 Mac Addr
2. If value is FF:FF:FF:FF:FF:FF – this means MAC was not added during production of mainboard.
Solution to fix this issue: Request new MAC addresses from TV manufacturer.
3. If value is different than FF:FF:FF:FF:FF:FF – Means current address is not supported by software.
Solution to fix this issue: Upgrade TV software to the latest version.
