The batteries dies in my W10000 remote control.
I replaced them and now the remote stays illuminated and won't work.
The batteries were NOT placed in reverse polarity.
I check the PCB and the 455KHz ceramic resonator was not running so I replaced it.
The remote still doesn't work.
Your site says these are not in stock: https://www.benqdirect.com/benq-projector-remote-for-pe8720-w10000-w9000.html
Where can purchase and new remote?
Sorry to hear about your remote not working. Unfortunately we do not repair remotes. That projector is EOL or End of Life.
We no longer carry the remote or accessories for it. You may be able to find a replacement on eBay.
Sorry about that
