Question about Televison & Video
Screen went blank. I have sound and images with flashlight test, no backlights. Now trying to determine it pwer supply / led board is bad or if leds are bad. Thanks
Your power supply board is working if you get audio and imgaes.
You test AC only the AC side of the transformer before the Rectifier Diodes. Everything after the Diodes will be in DC.
did you get to see any spec of backlight as shown in
