Hitachi 42" 100Hz Freeview HD LED TV - (42HXT12U)

This has been a great TV it has been wall mounted since new and recently the screen has gone black but we can hear sound and even programmes are working , everything normal but no picture! I had a play around with the remote to try and find settings but I can’t get a screen to show a picture I have changed batteries and switched on and off etc to no different result. I have a new tv - this may be a simple fix for someone - open to offers
