thanks for that response, it is something i will check and see if it helps. I have had a good response from the replaced LED's. The other thing i did think of was that maybe there is some sort of delay after selecting which device you want. If you learned say 20 buttons for the TV functions, and then you were on dvd, and decide to switch to TV, I was thinking that there was a delay before all the buttons would actually function. Of course i dont know the first thing about the programming of this remote, so who knows.
All I know is the new LED's did help me a lot. Havent had any problems since, so I doubt there is a delay.
