Not me. When I bought it, I left my 50A2000 at its factory-set settings for a few days, and even then the picture seemed pretty good. Tuned it with DVE, and it seemed even better. In both cases (pre-calibration and post-), I've never had yellow (or any other colour) coming across as hot, which leads me to wonder if yours is defective.
Have you calibrated the picture at all? It might help a bit, but having Sony take a look at it would be a better choice.
