I have a Sony KP-53HS30 that I purchased in July. I have set it up with Avia, and I had a service call on it in October to set convergence and focus. I just replaced my DVD player so this weekend I used the Avia to reset audio and video. While I was at it, I put up the Avia convergence grid, and I noticed that the blue was way off on the vertical (2-3 pixels or more). I have recently pulled all of the equipemt away from it's normal position to re-cable and put in cable management, but I rolled the TV only about 2' across carpet so this should not have affected the convergence. What I am wondering is whether or not this is normal to have the convergence be off after 4 months, and how often should convergence need to be touched up. I have a service contract on my set so I am going to have them come back out and set the covergence again. BTW when they set convergence, do they set it for different inputs, different resolutions (480i, 480p) or is it just a single mode, I know that last time they only set the convergence one time. Thanks in advance for any information on this it will be helpful for when I schedule the service call so that I can make sure that convergence is set correctly.
