I adjusted my convergence on my hdtv, but there is still a blurred picture. I have a digital cable box hooked up to the television that was professionally installed. I used the manual convergence settings as well as the automatic settings. With the digital cable box the picture is a little better, but I still don't have a totally clear picture.

Your convergence circuit has most likely failed. This can be a problem with the convergence power supply, convergence amp bd. or even the deflection/power bd. I would suggest a qualified tech to determine which is te problem.
