Westinghouse Model LTV-32w3 HD goes green with the look of a negative image intermittant. Comcast tech checked it on and off the box. Used our DVD player and same results. Bought it at the Moffet Field Navy Exchange which has since closed. Any suggestions?

  I am having this problem also with my westinghouse model LTV-32w3 HD.  In all other respects I like it, but the problem starts about 20 or 30 minutes in, then flickers intermittently sometimes going normal sometimes not.  
  I did notice that adjusting the contrast and brightness have an affect on it, reducing some of the effect but not resolving it.   It seems that its worst in the blacks and some places will look perfectly normal but the surrounding image is filled with green and jittery video noise. Perhaps were contrasts are higher?
  Occassionally the picture will also 'Roll' swiftly with blue and black horizontal bands in 3 or 4 columns.    Sometimes if I leave it on anyway it will eventually come back.   Sometimes it comes back for hours, sometimes it starts going green again.

We bought our TV from HSN it worked fine for awhile with a great picture after awhile it started to roll for awhile then straighten out for awhile with a good picture but then starts rolling again.
