    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.

    Convergence drifts over time ... much like your car's performance changes.

    Touch up convergence every 3 to 4 months is very reasonable.

    Michael,

    Thanks for the input. Can you tell me what modes need to have convergence set. I have the following equipment attached to the set


    Progressive DVD Video 5 Component 480p
    DishNetwork Receiver Video 3 S-Video 480i
    JVC S-VHS Video 1 S-Video 480i

    Is there just a single convergence, or is there one for each input and input mode.

    There is only one. Just make sure your set has been warmed up for 20-30 minutes prior to adjustment.

    On the HS30 ... you'd likely need to do the 4:3 mode ... then the 16:9 mode and double check the 1080i mode too.

    480i/p should be the same ... "should" be.

    You may have to manually go to 16:9 after you enter the service menu in order to do that part of the convergence.
