Samsung TXN2020 20" TV
unfixable problem!
This TV has a misaligned picture tube!  It is not fixable.  We were unable to reach Samsung by any means to have them rectify the problem; we could only return it, which we will as soon as our next one arrives.  We are very disappointed, although the picture quality is excellent and it's probably a great TV, but this is a manufacturing defect that spoils the TV's good qualities.  And Samsung's unavailability only compounds the problem. Next TV: not a Samsung!
