My Sony Bravia tv (not sure of the exact model as I don’t have the booklet) won’t stay switched on, it keeps coming up with the “Sony” load screen, then will stay on with a blank screen for 24 seconds before switching itself off and continuing to do the same process until you switch it off at the plug. I’ve tried doing a manual reset (holding the volume down and on button on the back in the tv) and this will solve it until the next time you turn the tv off at which point the next time you turn it on again it continues with the same issue. 

The TV is no more than 2 years old and for the price of it, should not be having these kinds of issues. Any solutions? Thanks
