Mine has been switching itself off and on for a few months, now. There will be a series of clicks, and the light is on and off, on and off. Normally, after a few seconds, it switches itself back on though i sometimes have to give it a helping hand. Then, last Thursday, whilst watching the afternoon's racing, it switched itself off and would not come back on no matter what i did with the remote. Not being technically savvy, and having checked all the connections, etc, i assumed that my ty had gone to that great broadcasting house in the sky. So i went through the very difficult task of bringing the 'spare' one from my bedroom. It is about as big as a house, weighs the same as a baby hippo and is quite an unsightly box, hence being hidden away upstairs; where it serves no other purpose than gathering dust, i can't watch tv in a horizontal position:-). Anyway, the only way to get this thing downstairs, because of it's width and weight, was backwards and step by step, a most arduous and hazardous procedure. By the time i reached the foot of the stairs, i was well cream-crackered. And, as i heaved it into the living room, i was greeted by the sight - and sound - of horses jumping over fences. And, if pushed, then; yes, i also heard the sound of my tv chuckling away!!
