Samsung UN40H5203AF LED backlight is blinking on and off. Set doesn't turn on.
If I unplug the LEDS from the power LED driver board, the set turns on, has sound and it passes the flashlight test.
On the BN44-00769C Power Supply / LED Board shows the LED supply voltage should be 151.8v at 425ma with the LEDs connected but I can't get good measurements on the LED connector with the LEDs blinking.
With the LEDs disconnected the open circuit voltage on pins 1 and 2 (D+) to chassis is 211v.
I thought I'd post to ask if the problem is more likely to be the LED strips or the Power Supply / LED Board.
