After I watch for awhile the picture will go away (both on a recorded disc and through the tuner) but the sound remains fine. Then the picture will come back and go away, etc. Any idea if a DVD lens cleaner will help or is it just a waste of money? Any idea what the problem would be (the connections and all seem just fine).

DVD lens cleaner would be a waste of money.

Well 99.99% of the time the symptoms you've described are due to loose or faulty Scart Lead connection.
But if you're certain the Scart connection is good and secure, it's best that you contact Panasonic Customer Support for service to this product.
