Hey everyone,

I just built this as my first pi project and I’ve run into similar power issues. I used the alternate HDMI cable linked on prerunnerseth’s website how to guide. For some reason the pi will loose power randomly and not reboot until I unplug and plug in the usb from the power injector again. Other times it will boot up repeatedly until it just stops and I’ll have to plug/unplug like before.

I know the pi itself is good because it runs great when powered by its micro usb. I’m not really sure what to do now.

Build complete, but, power issues. I got the recommended cord and USB power adaptor. I have completed all the wiring and setup on the Pi zero W but when I try to run the unit on HDMI ( with the USB power inline from my TV) it just hits the retropie screen and then reboots.

I have tried also plugging the USB power adapter into an outlet (2.1a source) and it does the same boot and reboot cycle. As I understand it this rebooting is indicative of a power issue, and as i have read on here there seem to be quite a few people with power issues.

Anyone have any ideas for a solution that do not requite me to run a seperate power cord? ( when i plug into the power outlet on the Pi it runs fine). Any help would be greatly appreciated.

If with a wall plug and 2.1A you can’t make it boot, it’s more likely a short somewhere. I can believe HDMI powering to be defective, but from wall plug... sounds just too much.
Just in case, did you try with another USB cable plugged for example in the PC USB port ? Just to really be sure

hey YaYa,

ok so i have firuged out how to make it work and what does not work. if i plug the power port on the pi into any power source it works. when i use the usb power adaptor through HDMI it does not work. i have now tried every HDMI cable in my house and none of them work. but again if i just plug the Pi into any normal power and HDMI into any normal TV, boom works fine. so im sure the Pi is not shorted as i can make it work fine. just seems to be when i try to get power through HDMI.

i guess it could either be i have no HDMI that will carry enough current, or that the USB adaptor is not functioning properly.

I finally got a USB port in from Digikey to add to mine- does anyone have any pictures of one added to their build? Also- which test pads on the pi do the jumpers need to be soldered to- just the two pads below the onboard USB on the pi itself?

EDIT: Nevermind - found images online. My test pads on the pi I am using do not have labels. PP22 is towards the power port - PP23 is towards the SD if anyone else runs into this.

Here's a link to the how to guide: https://www.sudomod.com/forum/viewtopic.php?f=22&t=2753

If you don't know how to solder those headers that tells me that you should practice soldering some things before you get invested in a project.

I had the same problem. Turned out my TV didn't like the power setup. On my TV I had to turn off anynet+. JLo
