LG TV Random LED Backlight Failure, Power Supply or Faulty LED?
My tv is LG 55LB671V. After some time ago my tv started turning off in a random time…. I opened the back cover of my tv and the LD701 LED was blinking 3 times every some seconds… I thought that maybe was the power board, but i also red that if the LED on the power board blinks for 3 times that means that i have an open LED strip. Also when the problem starts i have slound qnd i have not video but when i go closely to the tv on the up left corner i can see the video on my screen with my screen brightness to be very weak. Furthermore, when the problem occurs, i close and i open the tv and the screen is perfect with no problems after the next time. Some times my tv before shut down the screen it creates darck areas on my tv (you can see the screen behind but it is darker than other areas) and eventually my video wi turn off (with the sound to be okay) until i reopen it.
Can I chip in here with a related question? Very similar fault on an LG 55LB700V
