Fireflies E07 problems

I reviewed my FF E07 yesterday and after just a couple of hours of ha omg it the aux lights no longer work. One of the less burnt out. Because of the Corona pandemic I resorted to buying my FF E07 from eBay. The seller is a really nice dude, but he doesn’t do returns. And I’m not really willing to send it back to him and have him try to broker a resolution on my behalf with whoever he needs to. Any good advise will be greatly appreciated. He did suggest the possibility of buying the parts I need and attempting a repair myself( which I think I could do) but I’m not sure who has the aux board. Anyway help please lol

You could ask FF if they could send you a led board and solder it yourself. I think FF is a member here!

Mention that you are a member here and refer them to this thread

I am surprised this board works at all looking in the top section there is substantial mechanical damage to the Aux signal N-fet and C2 behind the LDO

I am able to make a replacement board or send you a prototype

How much would a replacement board be? I have sent a request for help to FF and am waiting for a reply from them, but I would greatly appreciate the alternative option. The light it’s self showed up with a couple of dings and scratches, I was surprised because the box appeared perfectly fine. But the light has minor seemingly superficial damage. But I didn’t think anything of it. I’ll update with pictures just to give you an idea. Either way please let me know how much your offer might cost me. Also do you happen to have or know where I can get a replacement lens. I VERY carelessly broke mine today showing a friend the board. I drop the lens on a concrete floor and it shattered(much like my hopes for a smooth process getting and using this light lol)

(Edit) the “damage” at the top is actually just thermal compound that smeared over the board when trying to reseat the optic. It was on the pegs of the optic from where it sits inside the board down in through to the main board.

That is not just thermal compound the parts are clearly almost torn off the board
