I replaced the power board, Tcon, main board. Still black screen. Can't see back light and cannot see image on screen with a flashlight.
Hi, the led or leds in the panel may shorted, thanks

Testimonial: "The LED driver has 266.9VDC on 1st Red wire, .090VDC on white wire and .160VDC on other red wire. I have a pic of wire layout but not sure how to upload. We can see an image on screed so def not backlighting. Replaced every board and didn't fix. Still sound like a short? Thanks for your help."
