VIEWING THE SELF CHECK DIAGNOSIS HISTORY
When an error is detected, the Self Check screen records the error that 
occurred. This is helpful in confirming past occurrences of an error, and for 
determining if an error is intermittent when the customer is not sure what 
is causing the television to shut down. If the screen displays a “0”, no error 
has occurred.   
You must got into Service Mode to access the Self Check menu.
1.  TV must be in Standby mode.
