No backlight but has power, did some tests
I have a LG 55lw5600 that's has no picture. It also has no backlights when powered on. I found a service manual online and started checking voltages. From the tests I have done so far I can tell the smps is good and the inverter is good (by tests that use jumper wires), the led lights come on during this test when ac power is applied. I have done the flashlight test and see nothing. Any ideas on which board or components may need to be replaced or what I should check to narrow it down farther.
Thanks for your time,
Third pic has my voltage results. The DRV-ON voltage is very low. And the t con fuse is not getting 12 volts. The last pic the the test I did, and that is the one when the backlights came on. I am just lost on where to go next.
Is this a good question?
