Keyboard model being used would help people solve your query?
I have seen that the Samsung KBD1000 & 1500 don't work with older models, and those below 6350!
I have a samsung ue32ts5500kxxu version 1. I haveconnected it to the network and everything works via the remote on the smart hub but it is so slow. I have just purchased the smart wireless keyboard and the pairing has been a problem. The on off to the tv works but the rest hows on the screen as not available then goes into pairingmode again. Cant seem to gert it to work, any ideas what I am doing wrong?
