All 3 indicators is noted about page 12 of the manual. http://www.fixyourdlp.com/manuals/Samsung/2eed9f9407e8137b3588.pdf
If you got your lamp from Samsung (and even if not) I'd call and check. In the US I start with 1800SAMSUNG.
Also, try unplugging the AC then removing and installing the lamp again. Sometimes.
I replace a new Philips bulb and TV still not work. There are humming noise (not high pitch grinding sound) and lamp light flashing when I turn TV on and when I turn it off, it start the clicking noise as TV try to turn on and off for a while and stop the noise and the front indicator (timer/ lamp/ standby/temp) start flashing.
I found out the new lamp is 100/120W and original is 120/132W. Is the original ballast will work? Or its a bad ballast need to be replaced?
