Hi. I have Sony SA-VA10 speakers, but have lost the original remote -- a RM-J10. I have:

1. Looked for a replacement on-line, but only found one for $75, which is too expensive.

2. I have a good Sony universal remote, RM-VZ320, but I can't find the correct remote code for the speakers, even though I've scoured the internet for it. (One guy somewhere said 0689, but that's a 4 digit code and my remote seems to want 5 digits.)

3. Tried the 991 trick, but that didn't work. (How many times do I have to push Aux/power?)

Any suggestions greatly appreciated.

Tony
