This sounds like a likely software fault on the TV, to better understand the fault can you clarify what you mean by half picture, is the picture resized to half of the screen or is half the TV blacked out?
Secondly when the TV turns itself off, does it come back on by itself?
Finally when you press the menu button on the remote does this display as expected without being distorted in any way?
I now understand, this isnt a tuner fault hence why the retune didnt work. I assume you have already tried a factory reset, this is unlikely to resolve the fault, however as this is only a 10 minute job and potentially save you a costly visit to the service centre its working doing, and can be access by going to Menu and then selecting the Support sub menu.
This sounds like a main PCB failure, which is resulting it producing a fault and the TV restarting itself. With this type of problem the only option is to replace the faulty board.
If the factory reset didnt work, please provide me with your post code I can recommend a suitable service centre, depending on your location it may well be worth repairing it.
No problem, appreciate if you can rate the service received.
