3.5 Inch Screen Converting to 5V Help

[BMO_16]

Do you use the same powersupply on the screen and the pi?

I don't get your question. I connected the screen red and black wire to the 5v and ground on the pi. I use a micro USB to power the pi from a samsung phone charger which outputs 2 amps. For now, that is how I power the pi as my power booster is not shipped yet.

Aren't the pp1 and pp6 pins on the pi for power input to the pi, not power output to another device as they are on the microusb which you will connect to a power socket... try putting the red 5V wire and black GND wire as indicated in picture below (or on any other pinhole which says 5V or GND, respectively)

Update: I tried the method you mentioned where the red 5v and black GND is on the GPIO. The screen still does the same behavior. I got my power booster in the mail today. I tried connecting the red 5v and black GND to the power booster V+ and V- instead of the Pi. I get the same behavior just as before.The 5v method should work, it feels hot and I tried multiple methods of powering on the screen. I'm going to assume the screen came me to broken and buy another one at this point.

Did this ever work out? I have the same screen but haven't done any modifications yet.

Me too I'm at a hault because of this screen

[Brandonmel]

Brother I'm having the same exact problem I've tried everything. When you turn it on it is a very very dim screen that just read no signal

[McGyver]

You need a signal! The Pi needs to run with config.txt configured to use composite output.

Is this how you guys are hooking this up?

[TheDeviantZen]

I have one screen exactly like this one. Had the same problem, and I just discovered that the wire bridge didn't work for me, I did like the picture below and worked fine

[Brandonmel]

I've tried everything that the wiki and the form has suggested i've never heard of anyone changing the video composite from HDMI to Video comp has anyone tired this ?

How do I configure it ? What do I need to change
