    Hello, I have a laser helmet for hair growth. One of the components has overheated and failed. The company wont sell me a replacement circuit board or tell me what the component is. Do you know? Is it even available?

    I can see a copper coil inside it. Here are the numbers on it but I couldn't find anything on the web

    Hi there Zapper
    welcome to EP :)

    Well its says BZ on the circuit board and that would indicate that it is a buzzer ... your observation of a coil inside
    supports that conclusion

    Thank you.

    I think you have pointed me in the right direction. It does indeed appear to be a a buzzer from a Nokia Lumia 820 but only one set of numbers match. This one:

    0091V 1.3

    What are the chances that the "1.3" indicates voltage?

    Pretty slim. :D
    I guess it's possible, but I reckon it's just a bit of the part number.
    I doubt if they have a fixed voltage like that - they're sort of like a little speaker, driven by an AC waveform. (I think.)

    Quite possibly. I considered that, but it's unusual that there's a space between V and 1.3

    I don't think the meaning of the number is too important in terms of using it. I'll bet that any near-identical buzzer would work fine.

    It's very unusual to see a buzzer burn up like that. Makes me wonder why, and if there's another underlying fault.

    I agree regarding burned up condition-there is more wrong to cause that

    Yeah, I thought I'd better mention that, so Zapper doesn't think that simply replacing the buzzer will necessarily fix the unit.
    Looks like the buzzer has had a pretty decent blast of DC, maybe. (Or worse - AC mains or lightning strike?.)

    Edit: I have no idea whether it's a battery or mains-operated device.

    Oh, really? How well did that work before the "buzzer" failed? Looks like a lot of circuitry just to grow some hair. Can you post "before" and "after" pictures? Where can we buy one?

    If you want your hair to grow, QVC is your world.
    They really work..
    I personally buy the in the ear and eye brow growers.
    I have yet to use the nose hair grower.
    Have you tried that?
    Please keep us informed.

    And here is a link... now on SALE for US$545.00! Save US$150.00! Looks like it includes ear hair attachment at no extra cost. No mention of nose hair or eyebrow option though.

    That is so funny, You cannot even joke without somebody with a forehead larger than mine selling a fix!!
    Reseeding hair is one thing, believing you can fix it! That is another thing.
    Going on National TV with a hair product!! And lacking hair to boot....
    Priceless..
