Re: Sony XBR75X850C won't power on, no LEDs
Unplug Tv. Remove all hdmi and usb from tv. Then push volume down and power button at same time on the tv, then plug it in and keep holding those buttons until you see the light turn white, then solid green. Sometimes it takes 60-90 seconds. Once you get the solid green insert a USB memory stick with the latest software installed on it and re-install the software. Follow the instructions and remove usb stick when it prompts to do so. If that doesn't work this model also has a history of bad backlights.
