Chosen Solution
Was given this TV when it wouldn’t come on and would love to get it working. It had audio and standby light, I replaced both boards and nothing changed. I’m not sure what the next option would be as I can’t tell what is left to replace related to the LEDs, or how realistic that might be. I can’t see anything doing the flashlight test, but I may not be doing it correctly. I don’t have a working multimeter at the moment but will get a new one soon. Also, the power button cover is broken off over the power LED, (came to me that way), could this have any impact? Thanks for any help!
@huskerhawk disconnect the main board from the power board and check to see if the backlight comes on. Since you already replaced the boards it is entirely possible that this is a backlight issue (possibly failed backlight strips). Let us know what you find. Here is a great video about the flashlight test.
