I just purchased a KDL-32W653A from John Lewis at the Trafford Centre in Manchester. I bought the TV as a Handwritten Branch markdown and have spent most of the evening trying to get the damned thing to work but all it does is switch off after 10 seconds whether it's playing anything or not.

I've searched the troubleshooting guide for answers and get the following response

TV turns off automatically.
1. Check if [Sleep Timer] is activated, or check the [Duration] setting of [On Timer].

A. If the sleep timer is activated it resets itself when the unit is turned off so it can't be that one.

2. Check if [Idle TV Standby] in [Eco] is activated.

A. Can't find any reference to any of these in the troubleshooting guide and besides how on earth am i going to be able to find all of this in 10 seconds.

Is there a factory reset button or another solution?

Am sorely tempted just to take the damned thing back and get a Samsung instead but thought i'd try here in case anyone had any clues as to an easy fix.

Thanks for reading
