Philips 27PT830H 27" Flat-Screen HD-Ready TV
Dave's right ladies and gents.
And here I thought that the reviewer above had just grabbed the short straw.  Turns out I've got the exact same problem.  The TV, right out of the box mind you, does not turn on.  It's not that it has no picture.  It just literally doesn't turn on.  Philips hasn't returned any emails, and the local shop (which is 40 odd miles away) doesn't even know where to start with this.  <br />Stay away from this product.  It's cursed.
