pi rebooting because of gearbest screen

[stef]

Hello everyone,

I recently had some problems with my gearbest screen, where a component would overheat after 20 minutes of use, destroying the controller board. Keep in mind my GBZ worked perfectly untill the screen died.

I recieved my new screen today, hooked it up the same way I did the first, and now my pi keeps rebooting, and screen is flickering. Powerboost is flashing red (low battery), green, and blue led like a maniac. I am powering my pi from a USB, and battery is disconnected.

I disconnected the screen ribbon cable as a test, and then the pi could boot normally (I heard the signature gameboy ping after boot).

My first thought is a shortage of power, because of the screenflicker and pi reboot.
I have the powerboost connected to the pi, and a second connection from the powerboost to a 'power strip', which only feeds the screen and audio amp.

Would it make sense to rewire the power from the powerboost straight to the screen? Or should I check my cables for some sort of damage?

Anyway, thanks to anyone taking the time to read this. And my best wishes to everyone for the new year!

Best regards,
Stef

Hey,

Topic can be closed.
I reconnected the battery and everything worked fine. Seems strange to me, i would think a power cable is enough... Maybe something to do with how safe shutdown switch works, I have no clue

If anyone in the future has problems with gearbest screens: I had a component of the controller board overheating, and I replaced the controller board, and the new controller board overheated after 20 minutes aswell. I replaced it a third time and again it started heating. So I switched the piback off and replaced the screen as well, nog the board does not heat. So for me it seems there was also a problem with the screen.
Now it's just the fun task of removing all the hot glue around the screen.

Best regards
