Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.
If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.

Well, I have had the same exact problem and since my hlp6163w is still under warranty, I had a technician come out to repair it. And...the winner is a bad ballast. The Ballast has also affected the bulb. So, the answer is you need to change the Ballast and the lamp to get the problem resolved. A faulty Ballast will always destroy a a lamp. Sorry for the bad news as this will cost you a total of $400.00 to replace. It sounds like there is a defect in the ballasts that were made for this particular set and a recall should be made. Hope this helps!
