Hi John,
I am working on the same Toshiba TV as mdnitehk. I also received the codes from Toshiba, but cant get the conversion to Pronto to work. I've tried using the makehex with nec.irp, nec2.irp and some others and then testing the codes with the Pronto TSU3500 with no luck. Reading your posts with mdnitehk it souds like you were able to get the conversion to work. I am currently using a macro for on/offs , but would like to get the discreets working. I thank everyone in advance.
