Hi, I have a problem with my screen. When I turn on the battery, the screen turns white. I know the Raspberry Pi is working because I have successfully hooked it up to a TV. I have tried the following:
-Taking out the orange ribbon cable and putting it back in.
-Disconnecting and re-connecting the HDMI cable.
-I also removed the screen and put it back in.
Any help would be appreciated. Thank you.
