I have a KD—55A1, working fine until I updated to the latest Oreo update (6.6520), all off a sudden has an issue were when it is on standby for a while, usually over night, it won't turn on without a power cycle.

No response when trying the power button on the remote or on the TV itself.

After tunring the power at the outlet off and back on, the TV responds normally to the remote or power button.

Is this in anyway related to known issues with other Bravia TVs? Does this happen with the latest Oreo update?
