where to get a new board?

  • erirohvel Saturday, February 16, 2013 10:44 AM Reply
    looks like the chip behind the led is dead because the lamp doesnt turn on... where to get a new one?

    it says hx-1105b1 on it and looks like this:

    also some "on A27 13540-" and "d436 ba7l1a" on 2 chips

    the switch and wires both give a beep on the multimeter....
    or is there a way to fix it?

    By "chip" do you mean the driver is dead? Does your multimeter have a diode test function you can use to test the LED?

    diode test gave ~0.540 ?
    the led did flash couple of times when i half-pressed the button down, but mostly the lamp is dead...

    by chip i prolly mean the board(driver?)... there are also two yellowish chips on the board... fuses perhaps?
    there are also 3 rings at the back... 2 of them beep, the middle one not...

    diameter is 26mm... this one will do then? -> sku.106303
    wonder if the original is 3kmA at all or something like 2.3?

    The small brown rectangular things are capacitors.

    "3kmA" is normally written 3A. The k and m cancel each other out (kilo and milli are opposites).

    Have you read the sticky in the Flashlight forum? It has links to threads about how to fix torches. What happens when you connect the battery negative directly to the torch body?

    Would you like to try reading those two again and tell me if you see a problem there? Hint: I didn't mention a multimeter or the tail cap switch.

    @desolder, all yours, if you like.

    bang your head against the wall and see if you get any different result for your regular day?

    desolder, for your reference:

    i have the xb-866 multimeter from dx, but dunno how to use a diode test.. it did flash couple of times tho when i half-pressed the button down, but mostly its dead.

    Without notice was changed to:

    diode test gave ~0.540 ?
    the led did flash couple of times when i half-pressed the button down, but mostly the lamp is dead...

    And the original title where to get new chip? has been changed to where to get a new board?
