Anyone experience this? Seems to only happen at night. System is connected to single HDMI and hardwired ethernet controlled by C4. C4 works flawlessly but when the TV turns itself on in the wee hours of the morning, C4 cannot turn it off - the OEM Sony remote must be used.

No help from Sony:

But some ideas in their forum - maybe Bravia Sync?:
