It took me awhile to scrounge these up. About a year ago, these codes were known, but not really posted anywhere I could find. I walked into an install I inherited and uploaded the remote file to find some hideous work around someone had used when they could only locate a couple discretes. I needed all 4 HDMI input calls. (I know, crazy right, how often does this happen).

URC pushed an update to CCP/TC recently (last couple weeks) that said they updated their DB for new sharp TVs. I have not looked at them to see if they work. I know the codes I have here do work.

I should mention, if you don't want to dig through the rhetoric on those links. I fired these codes at nearly a dozen sharp tvs. The LE650/550 series TVs did NOT respond the same way as all the others. I haven't encountered the LE643 series yet. I hope it's not the same as the 650/550, because there were some things I was unable to find discretes for, despite firing the entire 255 code set at it.
