What it means
Sony describes a blinking red LED as a warning that the TV is not working correctly and gives a sequence to follow in order. Seven blinks call for an overheating check first; for any other number, Sony's steps are a power off and on, disconnecting connected devices, unplugging for 30 seconds (a power cycle), a software update and a factory or forced factory data reset. If none helps, Sony asks you to contact customer support. The blinking does not identify which part has failed.
