Pi 3B will not power on with TFT50 v2 connected


Recommended Posts

I have a Raspberry Pi 3B with OctoPi up and running with no issue. it is using a 2.5A canakit power supply.

I purchased a PI TFT50 v2.0 screen and when the screen is connected to the Pi, it won't power, the Pi won't power on. If I disconnect the ribbon cable for the screen from the Pi, it will power on. I have tested this with no other accessories connected. No camera and not connected to the printer, just the Pi and the screen.

Could this be a power issue? Do I need more power than the 2.5A power supply will provide? If so, what should I get?
