I have a Proscan replacement HDTV. There are several problems with the picture...appears out of focus...in 4:3 material there is a bending of the picture on the left side(pincushioning?)...in the service mode, all of the various test patterns are shifted to the right about 2 inches...and there seems to be a convergence problem with phase grids on the right side. This poor convergence seems apparent when viewing any type of picture material. Has anyone experienced a degradation in picture quality from the original set? I'm also having a difficult time finding an authorized tech who knows anything about the set. The tuner seems better and the fan is not as loud as the original.
