I have the upgraded model of the Dbpower RD-810 projector. This one is advertised 3500 lumens. However, it quit working. The two wires to the COB do test at 12vdc. However, the COB will not illuminate.

After removing the COB and heat sink from their unit (de-soldered at the motherboard) I applied 12vdc to the wires - nothing. There's a little silver component that I've yet to identify. Has the markings ‘KAVASS BW-80B' - that seems to not exist on the internet.

Can anyone identify what this is, and/or recommend a suitable replacement?

Thanks,

Brian
