it cycles from 2 to 4 to 5 and back to 2 etc. works but the up and down rocker button for the chanel changing does not work. tried 0463 and no luck but a 2 blink feedback. Tested with non Mitsubishi codes and no feedback so I figured I at least have brand right (Is this a good assumption?) then came back to this site/thread and jotted down some codes. I tired the codes from the remotes documentation for Mitsubishi and they at least gave me a two blink feedback as suggested by the documentation. trouble is the remote wants 4 digits so I then tried adding a '0' in front and behind the codes (Precision or Mitsubishi - 218 or 102). Well no luck there so I got a 'ONEfor all' model URC 6131n remote and tired the 3 digit codes at the Insignia web site.
Got an IS-TV040928 - HDTV ready box at a discount with no remote or manual being told I could order one on-line.
