Hi, I am wondering about manually adjusting the convergence on my sony KP53HS30 rp tv. I have a download of the service manual and I think I could follow the procedure ok, however the manual appears to require some type of test generator for grid patterns, test dots and the like. Are they talking about an electronic device or can I get a DVD with the test patterns on it? Also some of the adjustments require capping two of the three lenses. Any adjustment of one color gun with the other two capped would have nothing to do with convergence would it? Nothing in the service manual specifically says anything about convergence but I gather that it is the same as alignment, is this correct? Also is the "Avia home theater set up" disk worth getting?
