Thank-You goldenzrule for the reply.
The old second TV died. I added the Vizio IR database into the spot the old TV was on the remote, that didn't work. Then tried to learn the power, vol up, and vol down for the Vizio and that didn't work either but I dealt with it because I could still change the channel through the DTV receiver and manually power the TV on and off. The main TV always worked after trying to add the Vizio until recently when the macros and punch throughs stopped working for the Sharp. The macros work all other components. I've reset the Sharp and nothing. Tried downloading the original MX-900 software that I saved prior to making any changes, nothing. When the MX-900 is plugged into the computer the macros and the punch throughs work like normal. When its unplugged it doesn't work. Not sure what to do next.
