The power board model is BN44-00774A. Backlight should light up with the main board cable disconnected from the power supply. If they don't, suspect LED strips though shorted LEDs have been known to cause failure in Samsung power supplies as well. Tricky to confirm without a LED tester. Tried, no backlight. A Samsung TV might have a dark screen because of either a failing backlight, incorrect PWM settings, or because of Eco Mode/Motion Lighting. You can change PWM settings in the Service Menu, usually accessed by pressing Mute + 1 + 8 + 2 + Power on your remote. Eco Mode and Motion Lighting can be changed from the Expert Settings in the Picture
POV: You’re watching Ted Lasso, and you can’t help but notice the picture on your TV seems unusually dark.Why does your Samsung TV keep dimming?Your Samsung TV Keeps Dimming due to the Ambient Light Detection function, a contrast imbalance, or maybe a weak signal.Turn up your brightness setting to 100% or turn the Energy Saving Mode off to help improve the dimness.

replaced the power supply board twice and still has no backlightBLU on/off voltage goes to 5 volts when turned on and to zero when turned off That means your TV panel is shutting down the power supply inverter due to a shorted LED array in the panel most likely.BN95-00883A is the panel, your VERSION number should be TS01 listed on the model stickerlI don't see any company stocking it, you
