By mistake I happened to use button A for programming the learn function for philips equipment.After doing so the remote control ceases to communicate with the DSP-AX2 AV amplifier.Then I proceeded the clearing learned functions (including removing the batteries for 24 hrs).Normally the remote will reset to factory preset and should function accordingly.
Infact I got the following results:
1.the remote only communicate with the AX2 with the
source display switched to zone2.
2.All functions are communicated except input-
selection, volume control & mute.

Can anyone help me to solve the problems.

Thanks.
