SOFTWARE UPGRADE

MSD6308 Upgrade Instruction
6308 including 6308RT, 6308RTE, 6308RTEB and 6308RTEC, you should make sure the main chipset correspond to the upgrade program before upgrading. This manual provides 3 upgrading methods with 6308RT as the example, the three methods are: User menu upgrade, Power on upgrade, TFTP (network) upgrade.

At the beginning of upgrading, if prompt “PWM-REF doesn’t match”, please make sure the new software PWM-REF won’t damage the panel, and then change the file name into AllUpgrade-6308-SOS.bin and power on to upgrade.

User Menu Upgrade
A Operation Procedure
• Turn on the TV set
• Copy the bin file to the root directory of USB device
• Plug the USB device to the USB port
• Select “Software Update (USB)” on the OSD and follow the instructions. TV will switch-off automatically after upgrading finished.

C Upgrade Flashing Status
You can judge the upgrade progress by flashing of the remote control LED light.
Upgrading
Red 1000ms Green1000ms alternates, the TV set will turn to Upgrade succeed or Upgrade Failed status after the upgrading process.
Main program upgrade succeed
Red 250ms Green 250ms alternates, flashing before power off.
Main program upgrade Failed
Red 1750ms Green 250ms alternates, flashing before power off.
• Notes:
• In the upgrade process, as timer software is used to control flashing, situations such as LED light stuck when creating partition of flash, is normal phenomenon.

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.
