I’ve got 55’ lg tv (model 55lw5600) and it recently stopped showing anything. the reason is backlight LEDs but im not sure if its led tapes itself or something in motheboard that is responsible for LED backlight.
starting screen (big logo) is backlighted normally but after 3 seconds its completly shut down. (rest of tv working fine, under da flashlight i can see what screen shows. audio is fine too)
if im not using tv for a while it can light the backlight for maybe 10 minutes and light shuts down
im finally not sure if LED strips got burn or some backlight hardware is damaged
for what i should look for?
