LG LED Model 47LN5750-UH Would like to know what part to try and replace. *Flashlight needed to view video (screen remains dark) *Audio ok *LG logo "flashes" very briefly on screen when tv is turned on, but after which nothing is visible without a flashlight. * No LED visible with back cover removed.
If you have good knowledge of repairing electronic equipment then check back light voltage in the power supply, if it is normal then you have to test the LED back light with external power. If it doesn't glow, dismantle LCD panel and follow the instructions how to check LEDs according to these links: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg... and https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor
