Can a DLP Lamp Be Tested Using Multi Meter?

I heard a pop sound on my Samsung DLP TV HL50A650C1F and picture went off while I am watching TV. I unpluged power for 5 minutes and turned on TV. The indicator light still steady light up like normal, but no sound and no picture. I took off lamp and use multi meter to test it just like I am testing regular light bulb. No connectivity! I went ahead to buy a new lamp and the new lamp has no connectivity, too. However, after installing the new lamp, TV is back. I visually checked old lamp and it looks like it is connected like new lamp. I am wondering does anyone knows can a DLP lamp be tested using multi meter? Thanks!

The only thing you can test for is voltage going to the lamp with a multimeter.

A DLP lamp cannot be tested with a multimeter in the fashion that you would test an incandescent lamp (common light bulb).

The meter will read "no connectivity" or nearly infinite ohms.
