While watching my Zenith roundie which gets very light usage, the vertical collapsed for a second then came back. It often jitters at the top an bottom as though the raster is about to collapse the vertical. This is about the fourth time I have had vertical problems with this set caused by varoius things. My tube type black and white sets while not immune to breakdowns are far more reliable with even more use. Also I noticed that the convergence needs touching up and the greyscale needs to be tweaked as well. I'm thinking it is just a little bit too maintenance intensive.
