Solving Issues With a PiBoy DMG Build

This tutorial covers several problems you might encounter with a newly built PiBoy DMG kit and how to troubleshoot them. Potential sources of trouble are: the two ribbons cables inside the case, a low battery and an improperly flashed RetroPie image. It is always possible that the PiBoy hardware itself is damaged but it is the least likely source of a problem. If none of these troubleshooting steps solve your problem contact Experimental Pi's support.

After turning the PiBoy on the LCD screen is dark and the power light never comes on

a. Check that that the battery is connected.
b. Plug in the USB charger. The power light should light up even if that battery is not connected.
c. If the power light is still not on check that the 18 pin ribbon cable in the case is connected.
d. If the power light still does not come on the PiBoy is damaged. Contact support.

After turning the PiBoy on the power light flashes green and then flashes red, finally the power light goes out. This means the PiBoy cannot communicate with the Raspberry Pi

a. Make sure the micro SD card has been properly flashed with the software. See our tutorial for instructions.
b. Hold the select button down while powering on the PiBoy. The LCD sceen will turn on and display the boot process. If the boot process freezes or fails contact support.
c. If the LCD screen still does not turn on check the following:
- LCD screen cable is correctly connected.
- 18 pin ribbon cable is correctly connected
- If both cables are correctly connected but the LCD screen still does not turn on, contact support.
d. If the LCD screen comes on but displays garbage:
- Check that config.txt has not been modified.
- Check that the LCD sceen cable is connected correctly.
- Check that the 18 pin ribbon cable is connected correctly.
- If none of the above problems are found contact support.
e. If the LCD screen comes on and the text is legible note when the boot fails. If the boot process does not fail and Emulation Station launches there may be a battery volatge reading problem causing a false shutdown. If this is the case contact support.
f. If booting fails before launching Emulation Station there may be a problem with the image. Reimage the SD card and try again. If booting still fails note where it failed and contact support.

If the LCD screen does not come on but the power light is solid red or green.

a. Force power off by turning off power switch and pressing the L3 button. The power light should turn off when L3 is released.
b. Hold the Start button while turning the PiBoy on.
c. The LCD screen should turn on and the boot process displayed. If booting failes re-image the SD card and try again.
d. If the Pi does not boot after re-flashing, turn off the PiBoy and remove the battery. Open the back of the PiBoy and lift if off. Plug the battery in, noting proper polarity, and turn the PiBoy on. Note the flashing of the red and green LEDs on the Pi. If the green LED flashes 4 times it means the Pi cannot read the SD card.
e. Open the latch holding the SD card adapter ribbon cable in place and removed the cable. Reseat the cable and close the latch. Once again try turning the PiBoy on and watching the LEDs on the Pi. If the Pi is booting normally the LED will blink sporadically.
f. If booting fails after the above steps contact support.
