recently completed a factory data reset after been advised to do so by a technician. (Our tv constantly had to be reset
for an unresponsive remote, Black screens with sound and no image, and problems with the screen freezing)
I have completed the reset- by going in to the settings on the TV (- Storage and Reset - Factory Data Reset)
The Tv then turns on, displays the Sony and Bravia icons, completes the Andriod icons and then only displays a grey background and the touchpad remote, with a thumb indicating that you need to press and select the command on the remote.
My TV is unresponsive to the remote. I only have one remote which is new RMF-TX100U
