Unable To Power On GPA 2.0
#1
Hello. I was hoping that I wouldn't have any major issues during my GPA 2.0 build, however, I seem to be have one now . . . If anyone can please assist, it would be incredibly appreciated.

I can plug my GPA 2.0 into a wall outlet and USB and a blue light glows. I believe that my 14500 3.7v Li-Ion batteries are charged enough to at least do a test. The green light on the GPA 2.0 board glows green temporarily and then fades slowly. The screen never powers on. I'm not sure what the issue is, does anyone know?

Thank you in advance for any assistance that you are able to provide.

Well, if the LCD doesn't come on, I would first suspect one of the following issues:
- The LCD ribbon is not secured. See: https://www.youtube.com/watch?v=sch5ZW1idz4
- The SD image you are using is not the one we provided on the Google Drive. If you use the one supplied by RetroPie, you will not get support for the LCD, Power Button, or built-in GPA buttons.
- You aren't holding the power button on long enough. Hold it until the green light comes on (but you must be using our SD image).
- Your Raspberry Pi is upside-down (which seems unlikely).

Do you have a way to plug in via HDMI? That can help track down the problem.

If you plug in power directly to the Raspberry Pi, does it power up?

Maybe the first thing would be to post some photos of the setup, so we can see if there's anything obviously wrong.

Thank you for your response!

When I plug it into the wall, it does not power up -- I just see a blue light that stays on.

As for the image that I'm using, it is the one from the Google Drive. Smile I even wrote it to the SD card using ApplePi Baker. Is there a different format that I should be using for the SD card?

I'll attach some pics tomorrow, right now I'm hesitant to take it apart since I've been working on the build almost all afternoon.

The blue light will indicate that it's charging. When it is fully charged, it should change to green.

Maybe post a picture of the cartridge opening, so we can see how the Pi is situated in there.

I was just able to take it all apart and the screen cable was a bit 'katty-wampus'. I corrected that and now the screen at least powers on . . . it only shows a white screen though.

Woohoo

This is good progress. The screen should be white while it's booting, and about halfway through booting it should come on completely with the RetroPie logo.

Hold the power button down until the green light comes on, and then let go of the power button. The screen should still be white for a few seconds, and then it will say RetroPie and finally boot all the way up.

Thank you for getting me this far! I'm pretty excited!

About how long should it take for it to boot? I've been waiting for about three minutes . . . which in other builds that I've done, my Pi Zero would have booted in about 30 seconds or so. Maybe I'm missing something?

No it's like 30 seconds. Does the green light come on?

This would be the green light would normally be just above where the X and Y buttons would be? If so, then no, that light does not come on.

Yeah, I'm talking about the LED above the X/Y buttons.
If you watch this video, you'll see how the bootup should look.

If that LED isn't coming on, then there's something wrong between the GPA and the Raspberry Pi, because the green light is a signal from the Raspberry Pi. It basically means that the Raspberry Pi has taken control of the power (On/Off).

If the Raspberry Pi is installed/soldered upside down, it may exhibit this behavior. Otherwise, I'd guess maybe a faulty solder joint (or broken pin) between the Pi and GPA.

This is where photos would really help.
