I am having the same problem between the older WD-***37 model and the newer WD-***38. I can not find discretes for the WD-73638, that is replacing the WD-73637 in our store. Mitsu's old "discretes only" setup of the factory remote no longer works. Anyone else have any ideas?

Thanks in advance.


*edit* I have discrete codes for the WD-***37 models, and the power codes do not work...

*update* After ongoing research, we have found that Mitsu WD**638 TVs do not support discrete power & input codes, only WD-**738 and WD-**838 TVs do.
