Hey,
I have a Samsung 55” 4K curves TV UN55KU6490F.
The TV started flashing it's backlights on and off. On for not even a second and stay off for up to a minute.
I pulled the back off and checked the voltages on the power board they seemed ok. I'll post a photo with them.
I pulled the panel off and checked the LEDs when they flash on they all flash on so I don't think it's the LEDs.
I started playing with the settings and found that when I have the backlights at 20 (scale is 0-20) the tv stays on and quickly flashes off once every couple of minutes.
The back lights are only at 71V across both sets when they are on. When measured individually set 1 is 43V set 2 is 41V. Doesn't seem high enough to me.
With the back lights at 10/20 (backlights off) there is still voltage on them set 1 34V and set 2 34V
Anyone had a similar issue or have any tips?
Sorry for the long winded message.
