Try to adjust the "Color convergence".
I don't know exactly where these settings are.
Go to Menu -> Advanced -> Page2:
Try to change the "Auto Adjust" to Off, then try to manually trim the "Horizontal", "Vertical", "Phase".
I suggest you to take a photo of the settings screen before changing the values for a possible return to the original state.

Model Nec VT47 wykonany jest w technologii LCD (układ 3 matryc RGB oraz pryzmatu). Usterka pokazana na zdjęciach, spowodowana jest przestawieniem matryc względem pryzmatu w torze optycznym projektora. Przyczyną przestawienia matryc może być np. upadek projektora, nieumiejętne czyszczenie toru optycznego. Często popełnianym błędem podczas konserwacji urządzenia jest demontaż matryc w celu ich wyczyszczenia. Ponowne, ich prawidłowe ustawienie jest możliwe do wykonania, jednakże jest to pracochłonna i wręcz chirurgiczna robota. W menu modelu VT47 nie ma możliwości korekty ustawień matryc. W tym przypadku najlepszym rozwiązaniem będzie wymiana projektora na nowszy egzemplarz lub kupno takiego samego modelu, np bez lampy.
