I have a Panasonic 36PD30. Overall I'm happy with it - it is certainly much better than my first set. However, I still feel the picture could be improved. Are there any CRT calibration companies that cover Sevenoaks/Kent area and improve issues such as geometry, convergence, colour (reds are a bit garish), etc. I'm not confident playing around with the service menu myself. How much do such services cost?
