Have you tuned the output voltage yet. There's a little trimmer you can tune with a screwdriver and a voltmeter. TUNE THAT TO 12V

There is not screw anywhere on my Pololu 12v stepup.

What is the voltage output?

Hmm.. something definitely is not correct here. I am only getting 3-4v out of VOUT.

Here is a video in case I did something incorrect. The first connection i tested was VOUT and the second one was VIN. VIN gets up to 4.5 something which should be fine. https://goo.gl/photos/JKZT3rDLmYrPFmbSA

+[mention]Felder[/mention] Maybe something is wrong with mine?

Felder did recommend to first connect it to a USB power source and then test the voltage to see if there is any difference. I will be doing this and report back. He also suggested that my step up puts out 200mA which may not be enough for my screen.

I am still Fleder, not Felder
Updated the other thread and it works for me.
Battery to PowerBoost to Step-Up to LCD.

Well if it's only outputting 3v it doesn't matter what mA it is. TBH best plan of action would be to buy another screen from a different place.

Why would this be the best plan?
He just needs to work out his wiring and it works, as you can see here.
Buying a new LCD just because you got the wiring wrong is not that smart.

Sorry as far as I knew I thought the screen had more issues than power. I thought it was broken.
