When you use a projector it automatically keeps a timer of how long the lamp has been used for. The message that comes up on screen saying "please replace the lamp" comes up not because it's some how sensing that the lamp is getting old, but because the lamp hours gets to a certain number (usually up around 1500 hours). Because of this when you replace the lamp you need to reset the lamp hours counter, or the projector doesn't even know you've changed it. Every projector does it this way, and they all do it a different way, I googled the model you gave us and found this set of instructions on how to do it, so give it a go.

Reset the lamp counter hours of operation for the projector SONY VPL-CX61
Using the remote commander while the unit is powered up, press "ENTER", "ENTER", "LEFT"
and "ENTER" in sequence. A prompt will appear on the screen asking if you wish to enter the factory mode.
Press the "UP" key on the remote and the unit is now in service mode. This sequence will add two new groups
to the customer setup menu. Press the "MENU" button to view.
Whenever the lamp is replaced, the lamp timer should be reset. With the unit in the "factory" mode, press
"RESET", "LEFT", "RIGHT" and "ENTER" on the remote commander. Verify the lamp hours have been reset to
zero in the service menu.

Hope this worked for you,
