Have any of you seen the tests on T.V. that either shows red if your tv is not ready for dtv and requires the converter box for which you get coupons for that or green to indicate that you need not take any further action? last week i saw one of those tests and it showed RED, that my tv was not dtv ready and that i needed one of those nifty converters. just now, another test happened and it showed GREEN, that my tv was just fine as it is. has anyone else had conflicting results from said tests? i do not have cable, satellite, dish or any other mode of tv reception other than the standard networks and PBS.
