White display on ILI9341 red board

Other Hardware Displays
1

I have seen a few posts of this fault. none of those helped. I have tried using the Adafruit library and ran the graphics code. I managed to get the opening test data back with the following results. I am using a Nano and tried several of them.

Display Power Mode: 0x94
MADCTL Mode: 0x48
Pixel Format: 0x5
Image Format: 0x80
Self Diagnostic: 0xC0

This would suggest that the wiring is correct. Hopefully the returned data is correct. After this there is a slight dimming of the display but then back to full white screen. I have also tried sever other libraries with the same result. Some wouldn't compile crashing on the SPI calls.
Hopefully someone has had the same results and can help me out with this.
Thanks for any help.

The un- categorized section is not for your posts, you should never post anything in it. It says so in the description of the section. Therefore I have moved your post here.

You might want to look at this How to get the best out of this forum to refresh your knowledge since things have changed since you were last here, before you proceed any further.

Thanks for that. I hardly ever use these forum things, except when I have an issue and the search engine sends me here. Then I just read them until I find an answer
Thanks
