i have D5720 which is bootlooping. I get the channel overlay and after a few seconds a restart. I read around the forum and tried these steps so far:
1) Factory Reset via service menu
2) Disable watchdog via service menu
I know that next thing would be the eeprom, but i wonder why the tv keeps restarting even with disabled watchdog?
Bye and Thanks
thanks for your reply.
its the tv of my grandparents and i guess they haven't done anything special. Maybe a over night firmware update, but the last one i found was mid last year...
Could it be that some caps on the motherboard are defective and does force that boot loop or do you have other things i should try.
Tv can restart if checksums of firmware partitions are wrong. This may happen (and often happens) because of firmware upgrade procedure failure/blackout/proccess interrupt for unknown reasons/internal flash failures etc.
