Samsung UN55hu7200fxza dim top half of screen

[nwelec]

This one the top half of the led strips are dimer than the lower half when the main board is plugged in. With the main board plugged into the power supply the voltages at pin 2 is 193v and pin 10 is 234v. When I unplug the main board from the power supply both pin 2 and 10 are 234v. I removed the panel and all of the led's look the same brightness so I am not sure if I am dealing with a bad set of led's or maybe a bad power supply. Any help would be appreciated.

I'd swap the 2 led strings around on the connector, plug it back in and retest. See if the problem moves.

Weak or dim Backlight strips at the top. Open up the Panel and replace ALL the Backlight strips wit NEW strips.

Do CapLeaker's test, remember what bud says, opening the panel is the last thing you want to do.
