Black Screen on LG LED TV. From what I can see, I have not backlight, but I have sound and I can see the picture with a flashlight...TV flashes on start up. Is the LED panel or the T-conn board ??.


LED backlight of your TV might gone. If you are a good service technician and know about electronic repair, check LED Driver voltage, if voltages are normal then you can test your LED backlight by applying external voltage to the LED backlight to reconfirm.

Samsung monitor 2232bw plus backlight fade in black backgrounds scenes


Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once.

If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...
