RESOLVING AN 8 BLINK ERROR
It’s possible that a customer may report an 8X blink error code even though
an 8X blink error isn’t an option in the Self Diagnosis Self Check list. An 8X
blink error is mainly used during TV software development. To verify that
there is an actual 8X error, view the TV’s Self Diagnosis Self Check list
history, specifically at the bottom of the list WDT (Watch Dog Timer) error
codes.
The 8X error code could be the result of:
The 8X error code could be the result of:
●
Software Issue
●
Network Issue
●
Skype Login Issue
●
Incompatible USB Device Plugged Inserted
●
Defective Main Board
Every time 3 errors are registered in the Self Diagnosis Self Check screen
the TV will shut down and activate an 8X blink pattern on the Standby LED.
If an error count is indicated, usually as an 103 HOST_WDT error, follow
these instructions to update the TV.
