I have a UN65NU8000 working with serial over EX-Link but the TV won't turn on sometimes. Looks like some kind of a power saving issue. I turned on IP Control in the regular menu to get serial going; anything else I'm missing? Something in the service menu?

Same issue with 2018 Q9
RS232 Codes confirmed and working for Power On and Power Off, when TV is on.
However, if TV is off for over 30 seconds, it will not come back on with "Power On" RS232 command.
Sharp TVs RS232 use to have a "wake up" RS232 command to send before "power On" would work.

Same issue with the 2018 Q9, Q8 and Frame 65 and 55.
I will post the solution when I figure it out.

Has anyone found a fix for this?
I looked in the service menu but could not find anything to do with ExLink/RS232

At least for Samsungs that use MDC Protocol (ME Series, and others), you have to retry to send command for "PowerOn" or "PowerOff" 3 times every 2 Seconds until ACK command. If there is no ACK within 3 times, It means failure.
Also check tv menu:
System -> Eco solution and System -> General
