Hello, I had aSony 61HS20 TV that had a few different problems that the technician could not resolve. One thing I noticed was that the green CRT seemed out of focus. In other words, when in the PJE grid, on the right 1/4 of the screen from top to bottom, the green line was double the thickness of the blue and red. This caused a very noticeable blurriness. It also appears on the bottom left of the screen to a lesser degree. I had the set replaced (not because of this) The new set, has a very similiar issue. But this time it is the red CRT and it is on the left 1/4 of the screen from top to bottom. The red lines in the PJE grid are 2x-3x the size of the green and blue. This makes adjusting convergence a pain since red peeks out on both sides of the lines and everything is again very blurry in this area. Seems like a focus problem. But my question is....is this normal? Do all sets do this when they are not properly focused? I suppose this could be one of those "comprimise" issues in which I have to adjust focus to look decent across the entire screen, but how do I know for sure? My concern is that the store I am buying from is selling second-hand factory refurbed units. The price I paid for a new set seemed much less that what others have mentioned for the same set, so I guess this could be the case.
