Hello,
The display does not respond to sample codes from the manufacturer's libraries. The only response is to illuminate the entire display in white. Connected as instructed: https://learn.adafruit.com/2-2-tft-display

Re: TFT LCD 2.2'' 320x240px color graphic display with micro
It could be a soldering issue. Looks like several pins are cold soldered and not wetted out enough:
https://learn.adafruit.com/adafruit-gui ... n-problems
Try reflowing them to see if you can get better adhesion to the pads. The amount of solder looks OK. So as a first attempt, don't add any more solder. Just reheat the existing with your iron and focus on getting *both* the pin and pad hot so the solder will flow on to both.

Thanks. Soldering looks much better.
Are you running the graphicstest example sketch from the library?
https://learn.adafruit.com/2-2-tft-disp ... 2978724-10
If not, what sketch are you running on the UNO?

Yes, I am running the example libraries from the example you uploaded.

Upload the sketch again and open the Arduino Serial Monitor. Do you see any output there?

That output does not match the example test sketch. Please make sure you are running the example from the library:

I checked again with the Adafruit_ILI9341 library - there is still a white screen.

What output do you get in the Serial Monitor when running this sketch?

Re: TFT LCD 2.2'' 320x240px color graphic display with micro
Hmm. All 0's in the responses - the 0x0 value reported for Display Power Mode, etc. So most likely still a connection issue of some kind.
Can you post another photo of your current setup showing how everything is connected. As much as possible, connect everything directly back to the main board. Don't use the power rail on the breadboard, etc.

The connection is the same. There is the same problem all the time.

Wire things directly pin-to-pin. Don't use the power rails on the breadboard.
Are the connecting wires themselves known to be good?

The customer needs a wired connection and this is the setting we are checking. The wires are working we also checked on others earlier (photo sent earlier).
