I have a KD-49XD8305 and I recently updated my TV firmware to 8.0 (oreo). Since then, every other day the TV wont turn on. It wont turn on with either the remote or the button on the TV. The only way I can get this to turn on is to unplug at the mains for about 15 seconds and when I plug it back in, it will allow me to turn on again. Anyone else having a similar issue since the update or know of any solution?
