malfunctioning bw screen

[TehCookie]

Hey, so I just got a bw display for my gbz build. I couldn't identify the variant so I decided to just hook 5v up to the Vin .
Picture of the board(thin red wire is composite signal): https://drive.google.com/open?id=1uI13d ... dEcscMWue5
All I got was this: https://youtu.be/PskXTBQ2N4Q
Then I hooked up 5v to pin 6 of the step down converter on my board. datasheet: http://www.ti.com/lit/ds/slvsaz6a/slvsaz6a.pdf
I didn't get anything on the display and the chip responsible for video got too hot to touch.
Any help would be appreciated

Update: I connected the display up to 12v and got this: https://drive.google.com/file/d/1M6ymah ... sp=sharing
I have confirmed the pi is working.

its looks like....
(from the video)
that the Raspberry Pi isn't getting enough power....
thats why its looping when booting up....

if you feel the power provided is enough....
(i'd still double check the power provided is enough/sufficient)
then also try with a fresh install of RetroPie...

Thanks, turns out it was the pi not getting enough power. Do know how to mod it to work off of 5v though? connecting 5v to pin6 of the boost ic didn't work because I used the wrong datasheet. Ill update this post when I find the right one.
