Now I have tried with a tft shield with components and only with wires (see my post just above) and I only get this screen.
Have seen in previous posts that others have had the same screen, but my being introduced only after I started to use O2's shield (ver. From 09.12.2014).
If I only use Arduino Mega with tft shield and screen works fine with touch screen.
Someone bid on what I might have done wrong.
