Tweaking your HDTV

Troubleshoot Your HDTV - Popular Mechanics

So you just bought an HDTV. You laid down serious cash for your new set, upgraded your tuner box and hooked it all into your surround-sound system. Then you turned it on and tuned into a whole new era of disappointment. Those HD pictures don't look as good as they should. The image breaks up into little blocks. Fast-moving objects aren't crisp. And standard-definition TV programs look like garbage. Is it your TV? Is it the fault of your cable or satellite company? The truth is that it could be either, or both. HDTV is still an evolving technology and plenty of glitches make it onto the screen. Some problems can be fixed with a simple adjustment, while others should send you back to the store with receipt in hand. And many problems have nothing to do with your set at all. Here's your troubleshooting guide.
