Re: sharp aquos LC-80LE632U led tv lamp error
The mainboard must generate only one signal the power supply gives it if backlight is in error. All other errors are generated from mainboard. Off the error pin if it goes high it generates a power supply fault codetwo quick flashes 5 slow flashes. The error pin stays low all tje time. Without or with the backlights working I believe the mainboard monitors this by the balancing of the data and clock signals generated by the backlight driver. The pins are called adl and acl
