Good evening friends.
This is my first post, and I have read several similar posts without a truly satisfying answer. So even though this has been **mostly** answered many, many times, I will repeat this in the sake of getting a clear answer:
- I have the Screen attached to the adapter board correctly
- I have the board attached to the RPi3 B, as per the guide as follows: the DSI ribbon flat cable to the adapter board and Pi, and the +5 and ground jumper cables to the GPIO in the Pi.
- I have an OFFICIAL 5.1v 2.5A Power Supply (not any other cheap, or kit supply, the official one!)
Things mostly work.
- If I power the system with the power inserted into the adapter board PWR IN (as per the instructions), I get a recurrent yellow 'thunder' on the right hand top side of the screen
- If I power the system (as NOT recommended in the instructions) directly to the Pi Power in, things work perfectly, no yellow bolt on sight.
Now, I am worried as, even though this works, the instructions clearly read:
"Do not power the setup via the Pi's micro-USB port: the input polyfuse's maximum current rating will be exceeded as the display consumes approximately 400mA".
What is happening? Why is the 'recommended' setup (and everything with the official components!) not working?
I would prefer not to use separate power supplies. But if that would be the case, do I need to unplug the jumper cables? Or do I just put two power supplies and leave the +5 and ground pins connected as well? (This is never clearly explained at all)
I really am worried and a bit upset that, even though I spent more for everything to be the 'official' product, things don't turn out as smooth as they should be.
Thanks for any feedback, best regards,
