Hi all,

So I've got an LED lit LCD monitor which I'm attempting to power.

I'm a little confused by the spec sheet which states a max input voltage of 42V, typical current of 18.5mA and max power consumption as 5.57W. There are two strings of LED lights, I would assume these specs are for both sets in parallel, correct?

What would an appropriate power supply to run these from a 110/230VAC source and also a second option for when I want to try for portability of 5VDC source. I figure since USB 3.0 can supply 5VDC at 0.9A that it should be able to power the backlight at roughly 80% duty.

Thank you all !

Edit: Sorry, the title should read "How to power..."

Do you have the original converter board from the monitor? - it is the power supply for the backlight. It'd be easier to rig a custom input to that.
