Well...I was NOT!!! able to find discrete codes for this Sharp HDTV set....I was however able to use an "anchor" command followed by a toggle in a macro to simulate discrete input and it works pretty well....Still no power discrete though....just power toggle....oh well...

I ream'ed Sharp tech about this and they were fairly understanding and apologetic.....Maybe they will do a "firm-up" that will correct the problem....I am confident it is a software/firmware issue and not a hardware issue..it can be corrected...and with any luck....it will be....
Installers beware!!!...Sharp is not including discrete codes in all there HDTV's....and as any pro installer knows...this can be a BITCH!!!

Thanks for all the responses and suggested code sets/hex (which didn't work BTW....but Thanks just the same....)
