Hi this could be lots of things, a dirty lens, a dirty lamp, or may be its the colour temperature settings, the colour temp as it is known will give a blueish or reddish colour to the white areas, maybe this is the problem, f you have a manual just check page 40, to 41 in the user manual you will find the settings there to adjust the colour temp, obviously do the normal things to, like clean the rear of the lens and the front, make sure you have not accidentally touched the lamp, just rub them over with a dry soft cloth the eliminate any finger marks that could have accidentally been put on them, if you still have problems get back to me and i will see if there is anything else that could be at fault....hope this helps

If the colors seems to be permanent in the picture the possibility off the LCD imager being faulty is high.
So as the color patch is from the start up , it seems to be a failure or burn up on the LCD.
Need to confirm if this happened when the lamp was changed or was it there before the lamp was replaced.
You can remove and care fully check the display and board settings, fix back all connectors on the main board. If there was an absence of colour we could have assumed the processor board but the patch seems most likely with the LCD.
Be very careful and attempt only with proper tools in dust free enviourment. removing and connecting cords and wires must be done with care.
