Screen problem

Post by Paxe87 » Wed Jan 09, 2019 10:57 am

Hi guys, I have a question for you
I just received my display unfortunately I have no idea how to convert it 12V to 5V
is very similar to those from the guide, however, it is not the same :(

If your board has the XL1509 chip responsible for converting the 12v input to 5v then read my GearBest Screen 5v mod post.

Thank you,
I read and look easy, but I did not find these components on my board. I have those

You could just google those numbers and find some data sheets on those chips. Also, if you have a 12V power source and a multi-meter. Power the screen with 12V and probe those chips and find a spot where 5V is being output, and connect your 5V power there.

This is exactly how I do the 5v mod to any 12V screen for Game Boy Zero. These screens use different dc regulators but they're all basically the same. They take 12v input and convert that to 5v.

I got a few of these too since they were running on special on amazon. The pin you want is pin 2 on the 2013s chip.

Btw. Nice photos... it took me quite a few tries in zooming and angling to try and get my phone’s camera to read the writing on the chips. Once I did that, I googled around with those various numbers till I found the schematics for 2013s which looked pretty promising, with 5v on it. Multimeter tests seemed to agree when I had it powered through the standard 12v in. I’ve wired up three like that and they worked like gangbusters.

For anyone with the same screen, the schematics is at http://img009.hc360.cn/m8/M07/AA/BB/wKh ... jTI860.pdf.

Connect your 5v directly to the RZC2013S' pin 3.

Thanks,

did this work with pin 2 because that is the 12v in, and the pin 3 is the 5v out? so pin 2 works the same as if you just use the input pad?
