Why is my TV not displaying? Three LED blinks.
Hello Community,
ANSWERS:
"Hi @ericlg
I’m assuming that the LED voltage measurements are between the pins and Earth, is this correct?
Did you try measuring between LED1+ & LED1- and LED 2+ and LED 2- to see what it measures?
I would check that all the strips are working OK. You may have to access the strips and check that the power is getting to or through the middle LED strips.
Try using a TV backlight tester to make it easier. That way you won’t have to have power on the TV to check the LEDs and you won’t have to disassemble the TV to get to the LEDs if they all work when a tester is connected to power them. If they all work with the tester it is back in the power board. If they don’t it’s in the LED array somewhere"
