What are your temps? Temps that are too cool will slow a turtle down. Also, if the water is cool but the basking area is toasty warm, your turtle will be more inclined to bask - they are heat-seakers. For a grown RES, water temp of 75 degrees fahrenheit is good, basking temp of 90 degrees. For a RES under 4", water temp should be a few degrees higher.
Also, a light bulb that is irritating a turtle's eyes will make him avoid the basking area. With the irritating light is gone, he may feel more like basking.
On the other hand, I usually trust people's instincts on these matters. You know your turtle's behavior better than anyone else. If it's worrying you, then by all means take him to see a vet. The worst that can happen is that he gets a good report.
For people taking their turtles to the vet's, here's a standard caution. If the vet offers to give a vitamin A shot, first make sure the vet is positive your turtle really needs vitamin A and then discuss other alternatives to shots with the vet like eye drops with vitamin A, cod liver oil or food supplements. Several turtles have recently had very bad reactions to vitamin A shots and I think it's best that if vitamin A is needed (and often it's not) the safer methods be used instead.
