Hi everyone, I'm new here and I hope that we have a great time here in this forum!
I have a mp3player that has blown the led backlight of LCD, so I want to fix this.
I measured the input voltage for leds and it was 24volts for 3 LEDs! (new leds get very hot under load and I know they might burn too) so I want to reduce voltage to 9 volts if it's possible.
I was thinking about shorting this inductor :
(it converts 3.7v to 8-9volts )
also the inverter transistor (D256A) next to this inductor gets very Hot without LEDs connected.
