24v DC to 12v DC converter for LED backlight

[PJALM]

If I try connecting 2 LED strips in series the internal power supply just clicks and turns off and on. Maybe this whole time there was nothing wrong with the original backlights and was the internal power supplies at fault the whole time lol. Too late now, I allready converted them all to LED backlights.

Well the power supplies seem to be fine so I am going to continue with this project. Until I manage to get the 24v-12v DC/DC converters I am going to use the external 12v PS and start building the PWM control board and see if I can start writing the code.
