I just purchased a Panasonic TC-P42X5 plasma tv. I have an HR20-700 with an RC65 remote. I cannot get the on and off buttons on the remote to turn the tv on or off with the HR20. Volume up/down, mute, and tv input all work. If I slide the selector switch on the remote to tv and press the pwr button, the tv will toggle on/off. I tried an RC24 remote and get the same results. I checked http://www.directv.com/DTVAPP/global/contentPageIF.jsp?assetId=P6420119#h:620.558. Tried all the codes provided as well as stepnset with no luck. I had an older Panasonic LCD TV that operated correctly with the same remote. Anyone been able to get later generation Panasonic tv's to respond correctly to the Directv remote on and off buttons?
