Sony Smart TV No Display Red LED Blinking Issue Fixed

This KD-60X6700E smart tv had no display and there was a quickly flashing sony logo when I keep the TV in a dark room (If not it is very difficult to see). The standby LED was flashing 6 times in red color after flashing the logo. The issue was that two LEDs are weak in the backlight LED array. They were emitting little blue color light and all other LEDs were emitting white color. Then I replaced those two bad LEDs and the issue was fixed. When LEDs are getting old some LEDs starting blue light emitting and we can see them as blue light spots on the screen in some TVs (Specially in old Samsung tvs). But this Sony Tv detects it as a fault and completely turn off the tv by it self as a result of the error detection circuit. KEEP IN MIND TO REPLACE ALL BLUE LIGHT EMITTING LEDS AS DEFECTIVE, WHEN YOU CHECK THE BACKLIGHT LEDS.
