Hello, 

My Samsung QN82Q70RAFXZA Flat 82-Inch QLED 4K Q70 Series just started flickering one day and wont respond to inputs from the remote. It also wont turn off from the power button on the TV. Once plugged in, it just flicker intermittently. 

The light at the power button continuously flashed twice, pauses then twice again, then once then starts the sequence all over again.

I've changed the following parts:

Samsung BN59-01314A (WCP730M) Wi-Fi and Bluetooth Wireless Module
Samsung BN44-00983B Power Supply / LED Board
Samsung BN44-00991A VSS LED Driver Board
Samsung BN94-14037E Main Board for QN82Q7DRAFXZA (Version FA01)

But nothing changed.

what other component would cause this behavior?
