The edge LEDs backlight flashed twice and then dark.
I have checked each of the LEDs one by one, they all flash twice with an interval of 5 seconds. It seems the LEDs are OK, but why they only flash and dark again? I used black tape to cover 55 LEDs (total 56 edge LEDs in one line), just left one LED out. So I switched on the TV by using the remote controller. Each LED flashed twice. BTW, when the LEDs flash, the total voltage reads about 80 volts, then it decreases to 23volts.
Could you please help? BTW, I can read German, but my writing is not great
