Samsung TXN2745FP 27" EDTV Monitor/TV with DynaFlat Picture Tube
Amendment to previous post
After being unable to clear the splotches, and being too tired to return the second set, I spent much of the night researching the problem on the net and by speaking with electronics minded people that I know. The consensus opinion was that the splotches likely resulted from static or magnetic buildup on the picture tube. These are supposed to be cleared by a degaussing circuit when the set is turned on. The next day, before returning the second unit, I turned it on and, lo and behold, the splotches were cleared.  Since that time (and through the Super Bowl) the picture has been tremendous. I felt compelled to post this experience as it may be that the degaussing circuit on these sets may not clear the field when the set is first turned on. Perhaps Samsung should warn users about this. The initial rating of &quot;3&quot; is rising fast. Still watching for reoccurence of the problem, however.
