WHERE's THE RESET SWITCH ON THIS THING?? (if any)

[theone999]

SAMSUNG DLP HL-S4676S

I replaced the bulb and this thing is still messed up. Hear some digital sounding beeps. Green lamp bulb flashes. Power on, more beeps, then ALL THREE lights in bottom right of unit flash. Sometimes it will stay on for a minute or two. Tried the menu+8+2+1 power code and still nothing. Is there some kind of reset switch on this??? Anyone? PLEASE and THANK YOU! <><

my service menu code was: with the set off, push menu, 1, 8, 2, power. Then scoll down to options, push enter. Power off after choosing lamp reset, and wait 2 minutes for fan to power off. My model is HLS4266W
