I'm running a Samsung 511 DVD player (replacement for the 709) with a Sherwood Newcastle R-925 dolby receiver. (The DVD player has no decoder... but the receiver does.) I'm experiencing dark banding on the TV screen which leaves only about a 2" horizontal area that is somewhat recognizable as a picture. This along with a chirping / clicking noise of about 250 cycles per minute or so. I find the receiver works just fine in all modes except DVD regardless of surround mode used.Not having spare components to try, I'm not sure if the DVD player's engine is biting the dust or if I have a dolby digital decoding issue within the receiver. These are my first DVD related components so I have no experience with symptoms that might obviously correlate to the offending circuitry.
If anyone has either a clue as to what has gone south or has experienced a similar problem, I'd sure appreciate a post here.

Follow Ups:
I forgot to mention that this "banding" seems to occur after the system has been running for 10 minutes or so. Sometimes shutting things down and restarting gives me clear pictures for a few minutes... more often no joy.To better describe the "banding" I'm not talking about any compression of the picture that might point to a monitor. I'm describing where the top third and bottom half of the screen darkly fog over leaving only that 2" wide horizontal band viewable with only that portion of the full picture recognizable... kinda like dark masking everything but the chest of a full figure.
Again, my TV, and all other modes of the dobly digital receiver work just fine... hence my thoughts that it's either the DVD player or the 5.1 decoding circuitry in the receiver.
Laser alignment had occured to me too but I've simply never heard / read of this type of problem at all, let along attributing it to the laser.
HELP please!!!!!!!

Everything you've said points to a problem with the DVD player. But, just to be sure, try a diiferent souce plugged into the DVD inputs on your receiver preferrably digital like Satelite TV or at least a VCR. Swap out cables if you have extra or just use some temporarily from another source. How are you connected ie video? 75 ohm coax or toslink? If 75 ohm are you sure that you are using a video cable and not an audio cable? Try the above just to be sure but I really think that you'll have to replace the DVD. Have you ever run your hand over the top of the DVD player to feel for heat? If so then do it again. Is it a lot hotter than it used to be? This could indicate a bad power supply.
Good Luck,
Bob
Try the composite video out and tha analog audio out from your DVD player.
