Chosen Solution
Hello, 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 Edit - adding another image:
Hi @randomrodder , It could be high resistance inside the component that is causing the voltage drop It’s a thermoswitch I’m not sure but I think that the 80B code might refer to its’ operating temp / reset temp. Here’s just one supplier of a compatible component if you can’t get just 1 from the first link
