Samsung LED TV UN55FH6030FXZA Screen Flickering

[mmagyvr]

I have a Samsung UN55FH6030FXZA and the screen is flickering even after replacing the power supply. I have tested the power supply output with and without LEDs plugged in, with the main board disconnected and with only the TCON board disconnected. With only the supply connected the i can still see the LEDs flicker through the back panel. I cannot locate the issue. The only consideration was the LEDs are going bad but was trying to diagnose without complete disassembly of the TV. Thoughts?
