SECTION 1 SELF DIAGNOSIS FUNCTION
LE-4B Self Diagnostic Software
LE-4B chassis TV’s contain a self diagnosis function. In the event of an error occurring, the STANDBY LED indicator will automatically begin
to flash. The number of times the STANDBY LED indicator flashes translates to a probable source of the problem. If an error symptom cannot
be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often
these problems occur.
