I have Dish 622 DVR remotes and am unable to program my Hanspree 32" HDTV LCD,Olevia 37 inch HDTV, or my Insignia 20" CRT TV. Tried power search (no luck), tried Sansui, Tatung, RCA, Philips codes with no luck. There are NO codes for any of the 3 codes I have in the manuals for the remote. Any help on any of the 3 TV's would be appreciated.
