Re: Sony XBR-65X810C Not Powering on

The update file (sony_dtv0FA50A09A0A9_00014300_153b00b8.pkg) must be copied or moved from the folder location to the root of your drive.

I have the same model with backlight not working. Mine is testing open from the connector plug(ch6801). I will work on it next week and let you know what i find.
