HDMI is a standard interface for standard and high definition video signals and is independent of the equipment that is connects. Ensure that any HDMI cable is HDMI 1.3 compliant. All licensed HDMI cables have been tested and approved for a maximum length. If the cable is properly licensed, it will operate without problems. Remember that price makes little difference - either the cable works or it doesn't. Make sure that the cable is bought from a reputable retailer and has the HDMI logo on it to ensure it is compliant.

HDMI cables should be manufactured to the HDMI standard and have the HDMI logo on the cable or packing. The logo should guarantee that the cable will operate correctly. Because HDMI is fully digital, a cable will either work or it won't. There will be no improvement in quality by purchasing more expensive cables. Claims by manufacturers that their cable must be used for "full quality" or "best quality" are misleading. Certain manufacturers offer cables in excess of $300. Be assured that they will provide EXACTLY the same quality of image and sound as a $10 cable. Of course, the $300 cable might look better! Although some cables may be more robust than others, this is only likely to make a difference if the cable will be repeatedly connected and disconnected. Other than that, expect the lowest cost cables to perform as well and last as long as the most expensive.
Assuming you have already tried unplugging the hdmi cable, and re-attaching it to make sure it is tight..... First, I would figure out if the hdmi output is bad on the DVD player, or if the hdmi input is bad on the tv, or if the hdmi cable is bad. Of course to do this, you would need a second hdmi capable tv, another hdmi source device and another hdmi cable. Once you figure out the source of the problem, decide it that component is worth replacing. Or, just run component.
