KLV-46XBR9, KLV-52XBR9 - Sony TV Service Manual (repair manual). Page 10

The units in this manual contain a self-diagnostic function. If an error occurs, the POWER/STANDBY LED indicator will automatically begin to fl ash. 
The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the POWER/STANDBY LED fl ash indicators is 
listed in the instruction manual for the user’s knowledge and reference. 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.

When an error occurs, the POWER/STANDBY LED indicator will fl ash a set number of times to indicate the possible cause of the problem. If there is 
more than one error, the indicator will identify the fi rst of the problem areas.
