KDF-E42/50A12U RM-ED002 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.
