Sorry, but it certainly does say in the DDJ-1000 quickstart manual:

Unfortunately this is not something covered by warranty, but the good news is you can replace the jog window with this part (DAH3189), which is the same part as on CDJs. If you're in Canada / USA, you can order it here. Unfortunately we can't provide instructions or information on disassembling the DDJ or performing this repair as we always recommend you have an authorized service shop perform any repairs or fixes.
