    maybe it has 2 problems.
    not turning off fully could be a leaky fet or a bad resistor on the fet,
    lets see the boards

    the other thing is the leds not all lighting together - it could be uneven leds but i would resolder those smd resistors

    white and something else - red?
    the resistors on the led panel look like they arent properly soldered.
    that doesnt explain it not turning off though!
    Sorry I’m mistaken, there are led’s where the orange lines are. There’s a knob that lets you adjust the light to a white/orange color as it turns on both the white and dim orange leds. But yeah I don’t know why when powered off the orange ones are still lit on 3 of the rows.

    LED light issue

    Hi, I'm trying to fix my buddies rechargeable led work light made by olight and the model is odiance. For some reason now after a couple years of no issue, when powered off now, the led is faintly lit on 3 of the orange rows but as you can see from the first pic that's not where the leds are. The part that is faintly lit is beside the leds? Anyone know how that is possible? Is there small voltage still coming in somehow? The third pic is with the cover off.
