Hi,
I recently bought two Raspberry Pi 3’s and having trouble with one of them.
It will not boot up past the ‘rainbow’ screen.
I have swapped over all the pieces from the Pi that is working (SD Card, HDMI, Power supply, TV) but cannot get it to work.
Had a look at the SD card pins to see if there was any broken, but they looked okay to me.
What else can I try?
