I own a 48OLED808 running the latest firmware (TPM231WW_R.001.001.091.215).
I found that the TV sometimes does not come out of standby. Neither by CEC, when another device is turned on that should turn on the TV, or by pressing the Standby button on the TV’s remote. It stays off. This has happened several times during the past few weeks. I had to remove power from the TV in order to fully restart it.
Is this a problem that others also experience, and is it something that can be fixed in firmware?
