Summary: I have owned this TV for almost 2 years to the day when it decided to die on me. The TV will power on for a few seconds and then the standby light will blink 4 times and won't power on again. I have tried everything to try and get it up and running again and it just doesn't want to work. I called the sony repairman and he told me that the LCD/LED panel went bad and that it would be cheaper to purchase a new TV rather then fixing it.
Summary: My husband and I bought Sony BRAVIA KDL46HX820 for $1393.00. First shipment we received within 2 months, we saw green strips along the bottom of the TV. Thank god Amazon was kind enough to replace it with no shipping charge. Fast forward 14 months later, one day the TV was playing fine then the system shut down with 4 blinking lights. We called Sony, which they were no help referred us to an authorized service center.

Summary: Stay away from this tv. Within 60 days, the screen had vertical lines and no picture. Phoned Sony and they said they would replace the tv or have it fixed. Customer rep said they had received numerous complaints against this model. Later they phoned and said the repair man said it could not be fixed. No repair man had even looked at the tv or even called. When the replacement came it was a refurbished model.

The set turns off after a few seconds and its little light blinks 4x followed by a pause and then 4 more blinks. Search online and you'll find out about what the number of diagnostic blinks signify.
