Here is the procedure for resetting the lamp timer.

This is a quick reference guide to show you how to reset your Samsung DLP TV’s lamp hour meter or hour counter. Resetting the counter is a very simple procedure.
Begin with the TV powered off.
Point your remote towards your TV.
Press:
Mute + 1 + 8 + 2 + Power.

Your TV set should now say “Loading Factory”.

Browse down to “Option” then press Enter (or the right cursor button).

NOTE: The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterwards!).

I hope this information allows you to resolve this issue.

push and hold the menu button on the front panel of the tv.
Do both actions simultaneously. Of course you have to be close to the tv to do this: pointing with the remote at the sensor AND holding the menu button of the tv panel.
Do this for some seconds and the screen is going to tell you the timer was reset sucesfull and ask you to push exit in the remote control to finish
