Hi
I bought a USB lamp, connected it to a 12V battery (by cutting the cord) and ruined it
Is it possible to fix/replace the borad which I assume was fried by my experiment, or some creative idea to wire it differently (preferably for 12v)? The on button is touch (no press) because it has several intensity settings (but willing to get rid of this as well if needed...). Here is a picture of the back side with board exposed.

Thanks

 

The chip is blown up, so it's dustbin time,, you could wire the light up to work on 12V if its an Led lamp by putting a resistor in series with it.

Is the lamp led or a bulb?

 

@Dodgydave - It's a led lamp, can you elaborate your suggestion? I guess you mean cut out the board & replace with something else.

 

So looking at the circuit, on 5V there are two 6.2 ohm resistors for the Yellow and White wires, I would say that the Red wire is the common Anode connector and the Yellow and White wires are for the Cathodes, to select the brightness, is there one or two leds in the lamp?

So if you want to run it on 12V , then you need a resistor value of 12 ohms to 15 ohms, and change the switch for a two way type or just on/ off.

All assuming the LEDs survived.
