12V Screen to 5V screen

[Jman11]

Yep, that was me that added the jumper cable. I had a 6V charger and did an A/B test between that and the 5V from USB and when it was on the USB, there was some slight video phasing. It was very minor and most people could probably live with it without modding it, but I decided on adding the jumper. Now there's no phasing on USB 5V and works great.

You're model looks exactly the same as mine. If you use a knife to gently remove the double sided foam tape, the board has this written on the backside: (that way you know for sure)

Make sure you have an active video source and at least 5V power or else your display will appear black/blank.

Also, lucky you. I didn't get the button daughter board with mine.

Do you have any suggestions on soldering that cable Popcorn? Ive done some soldering here and there but nothing that small.

Basically do you have any tips on connecting the wire to such a small area?

Well, pretty disapointing but it turns out that i have not the same/right screen as wermy showed.

This is what i got on the back of my screen: YZ035AU33

That screen on the right looks a lot like this one

Yeah my board does not look like the board from popcorn either.

No, you can cut the end of an old usb cable and solder the wires to the cable that most of the time comes with the screen, then plug this into the screen and the usb cable into a sufficient power source like an active USB Hub or a Wall Charger.

I tried to wire up my screen to an USB cable and connect the video cables like this:



I plugged in the USB cable to my notebook and the white and yellow video cable to my old gamecube.
Unfortunately the screen kept beeing black. It does not seem to me to turn on. There was only some sound coming from the board when i plugged in the USB cable.

Have i done something wrong in my wirering? Is it even possible to get this particular screen working with 5V?

Since my Rapberry Zero arrived today i tried to wire up the display like Wermy did:


When i powered up the rapberry zero the screen stared to flicker and i saw retropie boot up.

Has anyone an idea on how to fix that with this board?


I think the problem really is that the voltage is insufficent but how to fix that?

If you go here: http://www.sudomod.com/forum/viewtopic.php?f=8&t=15 I was posting some information about my screen I got from NiceShopping on amazon. It does run off 5v for mine, but it is poor quality and I do not get all the colors. It does seem like it needs 12v from reading amazon reviews. I ended up getting a 12v step up (http://www.amazon.com/Pololu-Step-Up-St ... ge_o00_s00) and will be installing it this week once it arrives.

My screen is different from popcorn I cause the displays US amazon folks are different.
