Working on a huge project with multiple TVs. Most are Sharp LC-52LE830UN, and the LC-70LE732UN. The rest are SONY. For some reason, the discrete power on and off were not working for the 3 TV's that were LC-42D69U. So I collected about 9 sets of codes from everywhere possible - this board, RTI library, URC library, etc. 9 sets of power on and off codes - and NONE worked. I cant figure out why this model is not accepting any. I used to have issues with Sharp a long time ago and thought the problems were over.

Does anyone out there work with or own this model? I am not sure what to do at this point - for the nature of this job discrete codes are vital and there is no chance for sensing equpment or any other way to deal with it. If anyone has any information on why this would happen or best case can vouch for codes that work I would be forever grateful. Very confusing problem.
