    Kenwood RC-R0825 remote failure

    Hi, I have this remote not working for the AV amplifier, is it fixable?

    The red led not works with any button, no IR emissions at any key stroke. Stopped working without a drop as far I know.

    Changed bateries, opened to clean pad, checked for broken welding joints, nothing found.

    Any other check that could be done or is definitely dead.

        I have opened one RC-R0730 and inside is the same board, perhaps only different eprom, because external are identical except the three pin Y1 component (don't know what it is)

        Will make readings to compare the visible resitors if I find some difference.

        If some one could point me some instructions.. any help is appreciated

          R9=180,4 ohms
          R5=1,2
          R4=100K
          R10=10 ohm
          R6=100Ohm
          C2= 122-- 96nf
          R35=1,09
          R54=0,002

          On the visible components there aren't much differnces, only the C2 is slightly different. The TP1-TP2 values and others TPx measured are different, but I don't know what they are.
          From the Y1s I unsoldered them and no readings could get on neither one.
