Sony KDL-40XBR4 Service Manual page 10

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED automatically begins to fl ash. The number of times
the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY LED fl ash indicators is listed in the instruction manual for
the user's knowledge and reference. If an error symptom is diffi cult to reproduce use the Remote Commander to display the record that is stored at the
internal NVM to specify the cause.
- One flash is not used for self-diagnosis.
