My Tv remote just stopped responding mid watch!  The tv was about to go into standby mode but I couldn’t continue as the remote wouldn’t react.  Changing the batteries didn’t work.  Did a tv update on settings using google app .after a lot of messing Ended up doing a full factory reset on the tv. At this point the tv remote is no longer paired and the app is also no longer connected.

spoke to Sony and have done a remote reset with them . Ended up buying a new control.

I am now at the stage where I have the welcome screen on the tv and need to select English to proceed. Which I can’t as the remote doesn’t work and with only 3 buttons on the back of the tv operating channel and volume. 
I can see the infrared flashing on both old and new control via my phone camera. 

tv is Sony Bravia KD-49XF9005.   Remote RMF-TX310E

can anyone help please ?
