the direct resistor fix did not work.

nor did the wire to the Vgh port on the driver board with a resistor

Re: samsung un65nu6900f common problem, digging deeper

I was gifted a non-working UN70NU6900F - same symptoms. I've determined that it is the right side of the driver board set (4 pieces) when viewed from the back. I can disconnect the flat cable between the two boards and start the TV with sound, and more often than not when I reconnect the flat cable (power ON) the picture comes on and TV works great until I shut it off.

I will try this fix (just replace the resistor) tonight and reply back.
